Cryptographic coprocessor with algorithm agility.

Cryptographic algorithm agility, i.e., the capability to switch between several encryption algorithms, has become a desirable feature due to the algorithm-independent design paradigm of modern security protocols. This MQP describes the design and implementation of an algorithm-agile cryptographic co-processor board. The core of the board is an FPGA, which can be dynamically configured with a variety of block ciphers. The FPGA is capable of data encryption at high speeds through an ISA bus interface. The board contains a Ram with an algorithm library, i.e., a collection of FPGA configuration files. The library can be updated during operation
