X-bit Labs reports Intel is working on a low-power hardware accelerator for the encryption and decryption of AES algorithms:
Intel Corp. recently demonstrated an implementation of a special-purpose hardware accelerator that can encrypt or decrypt media content using Advanced Encryption Standard (AES) algorithms. The chip that could process up to 53Gb/s of data consumed only 125mW.
Today's microprocessors need to compute more data than ever before, while maintaining a low power state for energy and battery life savings. AES is one of the most compute-intensive block ciphers for media content protection and data encryption on high-performance tera-scale microprocessor platforms. The exponential increase in data rates of real-time media processing and computational complexities of mapping modular Galois-field (GF) arithmetic and arbitrary permutations onto general-purpose microprocessors create substantial power and performance bottlenecks within the CPU core.
