Secure-IC Block Cipher IP is a hardware intellectual property solution that provides cryptographic functions for encrypting data. The product implements block cipher algorithms that divide large amounts of data into fixed-size blocks for encryption. The IP cores support multiple block cipher algorithms including AES, SM4, DES/TDES, RC4, and Kasumi. The product offers combined implementations such as AES/SM4-GCM and AES/SM4-XTS that allow multiple ciphers to share the same mode overlay. The solution supports various modes of operation including ECB, CBC, CFB, OFB, CTR, CMAC, CCM, GCM, GMAC, and XTS. These modes enable different use cases such as stream cipher transformation, data authenticity protection, and combined confidentiality and authenticity. The IP cores include optional protection against side-channel attacks and offer tunable throughput and area parameters for optimization. The product provides AMBA interface support including APB, AHB, and AXI bus protocols for integration into system-on-chip designs. The block cipher IP is designed for hardware implementation in integrated circuits and FPGAs, targeting applications that require data confidentiality and authenticity at the hardware level.
