Secure-IC Hash & MAC Functions IP provides hardware IP cores for cryptographic hash and message authentication code (MAC) functions. The product implements hash functions as mathematical operations that transform long messages into fixed-size digests for integrity validation. Hash functions supported include SHA-1, SHA-2 variants (SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256), SHA-3 variants (SHA3-224, SHA3-256, SHA3-384, SHA3-512, SHAKE-128, SHAKE-256), Whirlpool, SM3, and MD5. The product also implements MAC functions that use hash functions combined with cryptographic secret keys to validate message authenticity and integrity. MAC implementations include HMAC variants based on SHA-1, SHA-2, SHA-3, and SM3, as well as CMAC and GMAC functions based on AES and SM4 block ciphers. The IP cores offer configurable throughput and area optimization, optional protection against side-channel attacks, and support for combining multiple hash functions within the same HMAC implementation. The product provides AMBA interface compatibility including APB, AHB, and AXI bus protocols for integration into system-on-chip designs.
