Registers from 0x54500000 to 0x54501000 are used to configure the host interface (HOST1X).
+
The TSEC's MMIO space is divided as follows:
−
 
+
* 0x54500000 to 0x54501000: THI (Tegra Host Interface)
−
Registers from 0x54501000 to 0x54502000 are a MMIO window for communicating with the Falcon microprocessor. From this range, the subset of registers from 0x54501400 to 0x54501FE8 are specific to the TSEC and are subdivided into:
+
* 0x54501000 to 0x54501400: [[#Falcon|FALCON (Falcon microcontroller)]]
−
* 0x54501400 to 0x54501500: SCP (Secure Crypto Processor?).
+
* 0x54501400 to 0x54501600: [[#SCP|SCP (Secure coprocessor)]]
−
* 0x54501500 to 0x54501600: TRNG (True Random Number Generator).
+
* 0x54501600 to 0x54501680: TFBIF (Tegra Framebuffer Interface)
−
* 0x54501600 to 0x54501700: TFBIF (Tegra Framebuffer Interface).
+
* 0x54501680 to 0x54501700: CG (Clock Gate)
−
* 0x54501700 to 0x54501800: DMA.
+
* 0x54501700 to 0x54501800: BAR0 (HOST1X device DMA)
−
* 0x54501800 to 0x54501900: TEGRA (miscellaneous interfaces).
+
* 0x54501800 to 0x54501900: TEGRA (Miscellaneous interfaces)

==== Entry ====
+
{| class="wikitable" border="1"
−
From non-secure mode, upon jumping to a page marked as secret, a secret fault occurs. This causes the CPU to verify the region specified in $cauth against the MAC loaded in $c6. If the comparison is successful, the valid bit (bit0) is set on all pages in the $cauth region, and $pc is set to the base of the $cauth region. If the comparsion fails, the CPU is halted.

−
==== Exit ====
+
Base address of the external memory buffer, shifted right by 8.
−
The CPU automatically goes back to non-secure mode when returning back into non-secret pages. When this happens, the valid bit (bit0) in the TLB flags is cleared for all secret pages.
 
  
−
==== Implementation ====
+
The current transfer address is calculated by adding [[#TSEC_FALCON_DMATRFFBOFFS|TSEC_FALCON_DMATRFFBOFFS]] to the base.
−
Under certain circumstances, it is possible to observe [[#csigauth|csigauth]] being briefly written to [[#TSEC_SCP_INSN_STAT|TSEC_SCP_INSN_STAT]] as "csigauth $c4 $c6" while the opcodes in [[#TSEC_SCP_AES_STAT|TSEC_SCP_AES_STAT]] are set to "cxsin" and "csigauth", respectively.
 
  
−
Via [[#TSEC_SCP_SEQ_CTL|TSEC_SCP_SEQ_CTL]] it can be observed that a 3-sized macro sequence is loaded into cs0 during a secure mode transition.

 +
=== Secure BootROM ===
 +
Certain Falcon CPUs may have an optional "Secure BootROM", but contrary to the common purpose of bootrom code, this doesn't execute while booting the CPU. In fact, being a microprocessor, Falcon is designed to execute user supplied code right off the bat in a clean slate state. However, Falcon can be paired with a [[#SCP|secure co-processor]] and provide a cryptosystem for any hardware block that may require it, originating what is known as a "secretful" unit.
 +
 
 +
Secretful Falcon CPUs have [[#TSEC_FALCON_HWCFG1|TSEC_FALCON_HWCFG1_SECURITY_MODEL]] set to 3, which means they support "Heavy Secure" mode (or "HS" for short). While in HS mode, the Falcon's DMEM and IMEM regions are protected from read and write operations, which effectively hides code and data from attackers.
 +
 
 +
Entering HS mode first requires uploading code marked as "secure" to Falcon, which can be done from MMIO using [[#TSEC_FALCON_IMEMC|TSEC_FALCON_IMEMC]] with the [[#TSEC_FALCON_IMEMC|TSEC_FALCON_IMEMC_SECURE]] bit set. Upon jumping to a page marked as secret, the [[#TSEC_FALCON_EXCI|INV_INS]] exception is raised which tells the Falcon to start executing the secure bootrom code.
 +
 
 +
The secure bootrom lives in a hidden ROM region, instead of IMEM, and is mapped as --x at address 0. On Falcon v5 CPUs its size is 0x367 bytes.
 +
 
 +
==== Initialization ====
 +
The first instructions of the secure bootrom simply save each [[#REG0-REG15|GPR]] to the stack and check the contents of the [[#SEC|SEC SPR]].
 +
 
 +
==== Authentication ====
 +
The main purpose of the secure bootrom is to authenticate the code pages marked as "secure". This is done by first extracting the base address and size of the region to authenticate from the [[#SEC|SEC SPR]], then calculating a signature over this region and finally comparing it to the value of the [[#SCP|SCP]] register $c6.
 +
 
 +
If the comparison is successful, bit 18 of [[#SEC|SEC SPR]] is set (which is mirrored in [[#TSEC_FALCON_SVEC_SPR|TSEC_FALCON_SVEC_SPR]]), the signature comparison result in [[#TSEC_SCP_STAT1|TSEC_SCP_STAT1]] is set to 3 and each page from the region to authenticate is marked as valid. Bit 19 of [[#SEC|SEC SPR]] is also automatically set, preventing any interrupts or exceptions from being raised while in HS mode, but contrary to bit 18 this one can be manually cleared by authenticated code.
 +
 
 +
Below is the authentication algorithm's pseudocode:
 +
<syntaxhighlight>
 +
...
 +
// This runs in a loop for each 0x100 bytes page.
 +
cs0begin 0x03
 +
cxsin $c4
 +
cenc $c3 $c5

==== Decryption ====
 +
If bit 17 is set in the [[#SEC|SEC SPR]], the secure bootrom will additionally attempt to decrypt the region to authenticate.
 +
 
 +
Below is the decryption algorithm's pseudocode:
 +
<syntaxhighlight>
 +
...
 +
// Use secret 0x06 as key.
 +
cs0begin 0x03
 +
cxsin $c3
 +
cdec $c4 $c3
 +
cxsout $c4
 +
csecret $c5 0x06
 +
ckexp $c5 $c5
 +
cs0exec 0x10
 +
ckeyreg $c5
 +
...
 +
</syntaxhighlight>
 +
 
 +
==== Exit ====
 +
The secure bootrom finishes by restoring each [[#REG0-REG15|GPR]] from stack and returning from the exception state. This will result in the authenticated code region being executed in HS mode until the current [[#PC|PC]] points to an address outside of the authenticated region. When this happens, each page from the authenticated region is automatically marked as invalid without any involvement of the secure bootrom, meaning that the secure bootrom is only invoked when entering HS mode.
 +
 
 +
== SCP ==
 +
"SCP" (Secure Co-Processor) is a proprietary coprocessor which can be found inside every [[#Falcon|Falcon]] that supports [[#Secure BootROM|Heavy Secure Mode]]. On the Tegra X1 these are TSECA, TSECB, NVDEC and the GPU's PMU.
 +
 
 +
=== Hardware ===
 +
SCP is subdivided into several specialized hardware blocks and interfaces.
 +
 
 +
==== LOAD ====
 +
Block for handling memory reads from SCP to Falcon. It communicates with Falcon over a dedicated interface.
 +
 
 +
The interface can be enabled or disabled by register [[#TSEC_SCP_CTL0|TSEC_SCP_CTL0]].
 +
 
 +
==== STORE ====
 +
Block for handling memory writes from Falcon to SCP. It communicates with Falcon over a dedicated interface.
 +
 
 +
The interface can be enabled or disabled by register [[#TSEC_SCP_CTL0|TSEC_SCP_CTL0]].
 +
 
 +
==== CMD ====
 +
Block for translating Falcon crypto operands into SCP commands. It communicates with Falcon over a dedicated interface.
 +
 
 +
The interface can be enabled or disabled by register [[#TSEC_SCP_CTL0|TSEC_SCP_CTL0]]. The status of the current command is reported through register [[#TSEC_SCP_CMD|TSEC_SCP_CMD]].
 +
 
 +
==== SEQ ====
 +
Block for recording and executing sequences of crypto operations in the form of macros.
 +
 
 +
Can be enabled or disabled by register [[#TSEC_SCP_CTL0|TSEC_SCP_CTL0]].
 +
 
 +
==== CTL ====
 +
Overseer block for controlling certain SCP features.
 +
 
 +
Can be enabled or disabled by register [[#TSEC_SCP_CTL0|TSEC_SCP_CTL0]].
 +
 
 +
Registers [[#TSEC_SCP_CTL_STAT|TSEC_SCP_CTL_STAT]], [[#TSEC_SCP_CTL_LOCK|TSEC_SCP_CTL_LOCK]], [[#TSEC_SCP_CTL_SCP|TSEC_SCP_CTL_SCP]], [[#TSEC_SCP_CTL_PKEY|TSEC_SCP_CTL_PKEY]] and [[#TSEC_SCP_CTL_DBG|TSEC_SCP_CTL_DBG]] refer to this block.
 +
 
 +
==== AES ====
 +
Block for providing AES-128-ECB functionality.
 +
 
 +
==== RNG ====
 +
Block for encapsulating and controlling the internal random number generator.
 +
 
 +
Can be enabled or disabled by register [[#TSEC_SCP_CTL1|TSEC_SCP_CTL1]] and reports the status of the internal random number generator through registers [[#TSEC_SCP_RNG_STAT0|TSEC_SCP_RNG_STAT0]] and [[#TSEC_SCP_RNG_STAT1|TSEC_SCP_RNG_STAT1]].
 +
 
 +
===== RND =====
 +
Internal random number generator.
 +
 
 +
Can be configured by the [[#TSEC_SCP_RND_CTL0|TSEC_SCP_RND_CTLx]] registers.

TSEC (Tegra Security Co-processor) is a dedicated unit powered by a NVIDIA Falcon microprocessor with crypto extensions.

Driver

A host driver for communicating with the TSEC is mapped to physical address 0x54500000 with a total size of 0x40000 bytes and exposes several registers.

Registers

The TSEC's MMIO space is divided as follows:

  • 0x54500000 to 0x54501000: THI (Tegra Host Interface)
  • 0x54501000 to 0x54501400: FALCON (Falcon microcontroller)
  • 0x54501400 to 0x54501600: SCP (Secure coprocessor)
  • 0x54501600 to 0x54501680: TFBIF (Tegra Framebuffer Interface)
  • 0x54501680 to 0x54501700: CG (Clock Gate)
  • 0x54501700 to 0x54501800: BAR0 (HOST1X device DMA)
  • 0x54501800 to 0x54501900: TEGRA (Miscellaneous interfaces)

CCR

This is a SPR (special purpose register) that holds configuration bits for the SCP DMA override functionality. The value of this register is set using the "cxset" instruction which provides a way to change the behavior of a variable amount of successively executed DMA-related instructions ("xdwait", "xdst" and "xdld").

Bits Description
0-4 Number of instructions the override is valid for (0x1F means infinite)
5 Crypto source/destination select 
0: Crypto register
1: Crypto stream
6 Bypass mode 
0: Disabled
1: Enabled
7 Internal memory select

Secure BootROM

Certain Falcon CPUs may have an optional "Secure BootROM", but contrary to the common purpose of bootrom code, this doesn't execute while booting the CPU. In fact, being a microprocessor, Falcon is designed to execute user supplied code right off the bat in a clean slate state. However, Falcon can be paired with a secure co-processor and provide a cryptosystem for any hardware block that may require it, originating what is known as a "secretful" unit.

Secretful Falcon CPUs have TSEC_FALCON_HWCFG1_SECURITY_MODEL set to 3, which means they support "Heavy Secure" mode (or "HS" for short). While in HS mode, the Falcon's DMEM and IMEM regions are protected from read and write operations, which effectively hides code and data from attackers.

Entering HS mode first requires uploading code marked as "secure" to Falcon, which can be done from MMIO using TSEC_FALCON_IMEMC with the TSEC_FALCON_IMEMC_SECURE bit set. Upon jumping to a page marked as secret, the INV_INS exception is raised which tells the Falcon to start executing the secure bootrom code.

The secure bootrom lives in a hidden ROM region, instead of IMEM, and is mapped as --x at address 0. On Falcon v5 CPUs its size is 0x367 bytes.

Initialization

The first instructions of the secure bootrom simply save each GPR to the stack and check the contents of the SEC SPR.

Authentication

The main purpose of the secure bootrom is to authenticate the code pages marked as "secure". This is done by first extracting the base address and size of the region to authenticate from the SEC SPR, then calculating a signature over this region and finally comparing it to the value of the SCP register $c6.

If the comparison is successful, bit 18 of SEC SPR is set (which is mirrored in TSEC_FALCON_SVEC_SPR), the signature comparison result in TSEC_SCP_STAT1 is set to 3 and each page from the region to authenticate is marked as valid. Bit 19 of SEC SPR is also automatically set, preventing any interrupts or exceptions from being raised while in HS mode, but contrary to bit 18 this one can be manually cleared by authenticated code.

Below is the authentication algorithm's pseudocode: 

...
// This runs in a loop for each 0x100 bytes page.
cs0begin 0x03
cxsin $c4
cenc $c3 $c5
cxor $c5 $c3
ckeyreg $c4
cxor $c5 $c5
cs0exec 0x11
...
// Use secret 0x01 as key and $c7 as seed.
csecret $c3 1
ckeyreg $c3
cenc $c3 $c7
ckeyreg $c3
cenc $c4 $c5
csigcmp $c4 $c6
...

Decryption

If bit 17 is set in the SEC SPR, the secure bootrom will additionally attempt to decrypt the region to authenticate.

Below is the decryption algorithm's pseudocode: 

...
// Use secret 0x06 as key.
cs0begin 0x03
cxsin $c3
cdec $c4 $c3
cxsout $c4
csecret $c5 0x06
ckexp $c5 $c5
cs0exec 0x10
ckeyreg $c5
...

Exit

The secure bootrom finishes by restoring each GPR from stack and returning from the exception state. This will result in the authenticated code region being executed in HS mode until the current PC points to an address outside of the authenticated region. When this happens, each page from the authenticated region is automatically marked as invalid without any involvement of the secure bootrom, meaning that the secure bootrom is only invoked when entering HS mode.

SCP

"SCP" (Secure Co-Processor) is a proprietary coprocessor which can be found inside every Falcon that supports Heavy Secure Mode. On the Tegra X1 these are TSECA, TSECB, NVDEC and the GPU's PMU.

Hardware

SCP is subdivided into several specialized hardware blocks and interfaces.

LOAD

Block for handling memory reads from SCP to Falcon. It communicates with Falcon over a dedicated interface.

The interface can be enabled or disabled by register TSEC_SCP_CTL0.

STORE

Block for handling memory writes from Falcon to SCP. It communicates with Falcon over a dedicated interface.

The interface can be enabled or disabled by register TSEC_SCP_CTL0.

CMD

Block for translating Falcon crypto operands into SCP commands. It communicates with Falcon over a dedicated interface.

The interface can be enabled or disabled by register TSEC_SCP_CTL0. The status of the current command is reported through register TSEC_SCP_CMD.

SEQ

Block for recording and executing sequences of crypto operations in the form of macros.

Can be enabled or disabled by register TSEC_SCP_CTL0.

CTL

Overseer block for controlling certain SCP features.

Can be enabled or disabled by register TSEC_SCP_CTL0.

Registers TSEC_SCP_CTL_STAT, TSEC_SCP_CTL_LOCK, TSEC_SCP_CTL_SCP, TSEC_SCP_CTL_PKEY and TSEC_SCP_CTL_DBG refer to this block.

AES

Block for providing AES-128-ECB functionality.

RNG

Block for encapsulating and controlling the internal random number generator.

Can be enabled or disabled by register TSEC_SCP_CTL1 and reports the status of the internal random number generator through registers TSEC_SCP_RNG_STAT0 and TSEC_SCP_RNG_STAT1.

RND

Internal random number generator.

Can be configured by the TSEC_SCP_RND_CTLx registers.

rnd

00000000: f5 3c 0X 90 crnd $cX

This instruction initializes a crypto register with random data.

Executing this instruction only succeeds if the RNG controller is enabled for the SCP, which requires taking the following steps:

Otherwise it hangs forever.

chmod

00000000: f5 3c XY a8 cchmod $cY 0X or 00000000: f5 3c XY a9 cchmod $cY 1X

This instruction takes a crypto register and a 5 bit immediate value which represents the ACLs mask to set.

sigcmp

00000000: f5 3c XY d8 csigcmp $cY $cX

Takes 2 crypto registers as operands and is automatically executed when jumping to a code region previously uploaded as secret. This instruction does not work in secure mode.

sigclr

00000000: f5 3c 00 e0 csigclr

This instruction takes no operands and clears the saved cauth signature used by the csigenc instruction.

ACLs

Each crypto register has an associated access control list with the following format:

Bit Description
0 Secure Keyable
1 Secure Readable
2 Insecure Keyable
3 Insecure Readable
4 Insecure Writeable

On boot, every crypto register has an ACL value of 0x1F.

In HS mode, STORE can always write to a crypto register. In NS and LS modes, STORE can only write to a crypto register if it has the Insecure Writeable access mode.

In HS mode, LOAD can only retrieve a crypto register's value if it has the Secure Readable access mode. In NS and LS modes, LOAD can only retrieve a crypto register's value if it has the Insecure Readable and Secure Readable access modes.

Loading a secret into a crypto register sets a per-secret ACL, unconditionally.

Secure Keyable

Controls if a crypto register can be used as key in HS mode.

Forced set if the crypto register has Secure Readable access. Once cleared, this access mode cannot be set again.

Secure Readable

Controls if a crypto register can be read in HS mode.

Once cleared, this access mode cannot be set again.

Insecure Keyable

Controls if a crypto register can be used as key in NS and LS modes.

Forced set if the crypto register has Insecure Readable access. This access mode cannot be set if the crypto register doesn't have Secure Keyable access.

Insecure Readable

Controls if a crypto register can be read in NS and LS modes.

This access mode cannot be set if the crypto register doesn't have Secure Readable access.

Insecure Writeable

Controls if a crypto register can be written to in NS and LS modes.

This access mode has no effect in HS mode.

Secrets

Heavy Secure Mode has access to 64 128-bit keys which are burned at factory. These keys can be loaded using the $csecret instruction which takes the target crypto register and the key index as arguments.

Secrets are specific to each Falcon unit with the exception of secret 0x3F. This secret is effectively empty (all zeros), but is configured to be overwritten with the KFUSE private key once the KFUSE clock is enabled. The KFUSE private key is console-unique.
