RSA and ECC Plaintext Key Injection not supported on SCE7 and SCE9 devices #258

Open michaelthomasj opened 1 year ago

michaelthomasj commented 1 year ago

Issue

In FSP v4.3.0, v4.4.0, and v4.5.0, the RSA and ECC plaintext key injection is supported on SCE7 (RA6M1, RA6M2 and RA6M3) and SCE9 (RA6M4, RA6M5, RA6E1, Ra4M2, RA4M3 and RA4E1) based devices via the SCE Key Injection module. However, the injected keys are not yet supported by PSA Crypto so are unusable for cryptographic operations. AES keys are supported.

Workaround

  1. Do not use ECC or RSA key injection on the SCE7 or SCE9 based devices.
