== Registers ==

−

~~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 ~~Co-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) and~~ CG (Clock Gate).

+

* 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)

+

=== 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:

+

+

...

+

// 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

+

...

+

</syntaxhighlight>

+

==== 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:

+

+

...

+

// 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 ~~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~~.

+

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.

−

+

==== ~~Implementation~~ ====

+

== SCP ==

−

~~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~~.

+

"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.

−

−

~~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~~.

==== rnd ====

+

+

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:

+

* Write 0x7FFF to [[#TSEC_SCP_RND_CTL0|TSEC_SCP_RND_CTL0]].

+

* Write 0x3FF0000 to [[#TSEC_SCP_RND_CTL1|TSEC_SCP_RND_CTL1]].

+

* Write 0xFF00 to [[#TSEC_SCP_RND_CTL11|TSEC_SCP_RND_CTL11]].

+

* Write 0x1000 to [[#TSEC_SCP_CTL1|TSEC_SCP_CTL1]].

Otherwise it hangs forever.

<code>00000000: f5 3c XY a8 cchmod $cY 0X</code> or <code>00000000: f5 3c XY a9 cchmod $cY 1X</code>

+

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

+

==== sigcmp ====

+

<code>00000000: f5 3c XY d8 csigcmp $cY $cX</code>

+

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.

+

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

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

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

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

~~For example, if override type=0b000, then the "length" argument to <code>xdst</code> is instead treated as the index of the target $cX register~~.

This access mode has no effect in HS mode.

=== Secrets ===

−

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

+

[[#Secure BootROM|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.
