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)

Heavy Secure Mode
Entry
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
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
Under certain circumstances, it is possible to observe sigcmp being briefly written to TSEC_SCP_CMD as "csigcmp $c4 $c6" while the opcodes in TSEC_SCP_STAT2 are set to "cxsin" and "csigcmp", respectively.
Via TSEC_SCP_DBG0 it can be observed that a 3-sized macro sequence is loaded into cs0 during a secure mode transition.
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.

sigcmp

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.
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 ACL mask to set.
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.
ACLs
Each crypto register has an associated access control list with the following format:
Bit
|
Description
|
0 |
Secure key. Forced set if bit1 is set. Once cleared, cannot be set again.
|
1 |
Secure readable. Once cleared, cannot be set again.
|
2 |
Insecure key. Forced set if bit3 is set. Forced clear if bit0 is clear. Can be toggled back and forth.
|
3 |
Insecure readable. Forced clear if bit1 is clear. Can be toggled back and forth.
|
4 |
Insecure overwritable. Can be toggled back and forth.
|
On boot, the ACL is 0x1F for all $cX.
Loading into $cX using xdst instruction sets ACL($cX) to 0x13 and 0x1F, for secure and insecure mode respectively.
Spilling a $cX to DMEM using xdld instruction is allowed if (ACL($cX) & 2) or (ACL($cX) & 8), for secure and insecure mode respectively.
Loading a secret into $cX sets a per-secret ACL, unconditionally.
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.
