The DAES core at Digital Core Design is a groundbreaking solution that leverages the Rijndael encryption algorithm, a cornerstone of modern cryptographic standards. Integrated into systems via APB, AHB, and AXI buses, this core supports both 128-bit and 256-bit key lengths, providing flexibility in encryption standards compliance. Its internal mechanism includes an advanced key expansion module, supporting various block cipher modes such as ECB, CBC, CFB, OFB, and CTR, ensuring secure encryption processes across multiple applications.
