The DAES processor is an ultra-secure cryptographic co-processor that efficiently implements the Rijndael encryption algorithm. This processor provides robust support for both 128 and 256-bit key lengths, while also facilitating a variety of block cipher modes such as ECB, CBC, and other standards. It incorporates an internal key expansion module to guarantee prompt and secure data encryption processes, positioning it as a vital asset for environments where data confidentiality is paramount. By integrating smoothly via APB, AHB, and AXI bus interfaces, it adapts seamlessly across differing systems requiring top-tier security.
