mbedTLS Crypto acceleration for CAT1A, CAT1B & CAT1C MCUs v2.5.0

What's Included?

Please refer to the README.md for a complete description of the CAT1A, CAT1B & CAT1C acceleration for mbedTLS library.

New in this release:

  • Added mbedTLS PSA HW accelerated driver support for CAT1B MCUs.

Limitations

Currently Cypress CAT1A & CAT1C acceleration doesn't support:

  • RSA
  • ECP NIST-B curves
  • ECP NIST-K curves
  • ECP 25519 curve
  • CHACHA20
  • SHA3
  • POLY1305

Currently Cypress CAT1B acceleration supports only

  • SHA256
  • ECC curves, ECDSA (Sign, Verify of curves P192R1, P224R1 & P521R1), ECDH

Currently Cypress CAT1B PSA acceleration supports only

  • AES-128 ECB and CBC (Encrypt), CFB and CTR (Encrypt, Decrypt), AES-CCM (AEAD)
  • RSA (Encrypt, Decrypt, Verify)
  • Elliptic Curve Cryptography (ECC) Key generation (Sign, Verify Hash)
  • SHA-256, HMAC-SHA256, HKDF, TRNG

Supported Software and Tools

This version of the CAT1A, CAT1B & CAT1C acceleration for mbedTLS library was validated for compatibility with the following Software and Tools:

Software and Tools Version
ModusToolbox Software Environment 3.2
mtb-pdl-cat1 Peripheral Driver Library (PDL) PSOC Control C3
