eSi-AES is a range of sophisticated AES cores for use in ASIC or FPGA technologies. They can be configured to customer the requirements to enable a flexible trade-off of key size, modes and throughput with area to get the most optimized solution. The base suite consists of Encryption, Decryption, Key Expansion and Cryptographic Mode modules that together cover all the combinations required for encryption and authentication. All modules support the three key sizes, dynamically selectable per-packet.
For the lowest gatecount the modules can be configured to support only one key size. In addition all modules are available with AMBA AHB or APB interfaces.
