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

Registers from 0x54500000 to 0x54501000 are used to configure the host interface (HOST1X).

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:

  • 0x54501400 to 0x54501500: SCP (Secure Crypto Processor?).
  • 0x54501500 to 0x54501600: TRNG (True Random Number Generator).
  • 0x54501600 to 0x54501700: TFBIF (Tegra Framebuffer Interface) and CG (Clock Gate).
  • 0x54501700 to 0x54501800: DMA.
  • 0x54501800 to 0x54501900: TEGRA (miscellaneous interfaces).

SCP

Part of the information here (which hasn't made it into envytools documentation yet) was shared by mwk from reverse engineering falcon processors over the years.

Authenticated 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 csigauth being briefly written to TSEC_SCP_INSN_STAT as "csigauth $c4 $c6" while the opcodes in TSEC_SCP_AES_STAT are set to "cxsin" and "csigauth", respectively.

Via TSEC_SCP_SEQ_CTL it can be observed that a 3-sized macro sequence is loaded into cs0 during a secure mode transition.

csigauth

00000000: f5 3c XY d8 csigauth $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.

csigclr

00000000: f5 3c 00 e0 csigclr

This instruction takes no operands and appears to clear the saved cauth signature used by the csigenc instruction.

cchmod

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.

crnd

00000000: f5 3c 0X 90 crnd $cX

This instruction initializes a crypto register with random data.

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

  • Write 0x7FFF to TSEC_TRNG_CLK_LIMIT_LOW.
  • Write 0x3FF0000 to TSEC_TRNG_CLK_LIMIT_HIGH.
  • Write 0xFF00 to TSEC_TRNG_CTL.
  • Write 0x1000 to TSEC_SCP_CTL1.

Otherwise it hangs forever.

ACL

Bit Meaning
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.

Initial values

On SCP 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.

cauth

$cauth is a special purpose register in the CPU.

Bits Description
0-7 Start of region to authenticate (in 0x100 pages)
8-15 Unknown
16 Use secret xfers
17 Region is encrypted
18 Unknown (set in HS mode)
19 Block traps and interrupts (set in HS mode)
20-23 Unknown
24-31 Size of region to authenticate (in 0x100 pages)

cxset

cxset instruction provides a way to change behavior of a variable amount of successively executed DMA-related instructions.

for example: 000000de: f4 3c 02 cxset 0x2

can be read as: dma_override(type=crypto_reg, count=2)

The argument to cxset specifies the type of behavior change in the top 3 bits, and the number of DMA-related instructions the effect lasts for in the lower 5 bits.

Bits Description
0-4 Number of instructions it is valid for (0x1f is a special value meaning infinitely many instructions -- until overriden by another cxset)
5 Crypto destination/source select (0=crypto register, 1=crypto stream)
6 External memory override (0=Disabled, 1=Enabled)
7 Internal memory select (0=DMEM, 1=IMEM)

DMA-Related Instructions

At least the following instructions may have changed behavior, and count against the cxset "count" argument: xdwait, xdst, xdld.

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

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.

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.
