CC2642R: ECC encryption API support

Shuyang Zhong

Part Number: CC2642R

Does CC26x2 has an API for ECC encryption and decryption (not for key exchange, but the stand-alone algorithm to encrypt a plain text)?

A customer is using the ECIES api as below from BouncyCastle library on their mobile app side in Java, and they want to find out does the similar api is supported on CC26x2.

void EncryptECC(uint8_t *in, uint32_t inlen, uint8_t *out, uint32_t *outlen, uint8_t *publicKey)

void DecryptECC(uint8_t *in, uint32_t inlen, uint8_t *out, uint32_t *outlen, uint8_t *privateKey)

Thanks!

Best regards,

Hi Shuyang,

The ECC functionality on the CC2642R is part of the Public Key Accelerator (PKA) hardware engine, a similar E2E post verifies that the ROM code is for verify/sign only. Here is a link to all TI Driver Runtime APIs. Another relevant E2E thread provides the location of ECC ROM functions in source\ti\devices\cc13x2_cc26x2\driverlib\rom_crypto.c

Ryan
