Detailed Description

RSA component.

The mcuxClRsa component implements the RSA functionality supported by CLNS. This includes RSA signature generation and verification, and encryption and decryption, according to PKCS#1 v2.2. The RSA component relies on the mcuxClMath component for modular arithmetic operations as well as the secure and non-secure exponentiation. It further relies on the mcuxHash component for the execution of hashing operations. The component offers the following functionality:

RSA signature generation and verification:
1. RSA signature generation using RSA keys in private plain or private CRT format together with the PKCS#1 v1.5 padding or PSS padding functionality, according to to RSASSA-PSS-SIGN or RSASSA-PKCS1-v1_5-SIGN of PKCS #1 v2.2.
2. RSA signature verification using RSA keys public format together with the PKCS#1 v1.5 padding or PSS verification functionality, according to to RSASSA-PSS-VERIFY or RSASSA-PKCS1-v1_5-VERIFY of PKCS #1 v2.2.
3. RSA signature generation primitive RSASP1 (exponentiation with public exponent) according to PKCS #1 v2.2.
4. RSA signature verification primitive RSAVP1 (exponentiation with RSA keys in private plain or private CRT format) according to PKCS #1 v2.2.
5. The bit-length of the modulus can vary from 1024 bits to 4096 bits.
6. The bit-length of the public exponent is limited to: of 2 <= e < N.
7. The bit-length of the private exponent is limited to: d < N.
RSA encryption and decryption: TODO CLNS-7925: update documentation for RSA.
