Abstract. MMX is a new technology to accelerate multimedia applications on Pentium processors. We report an implementation of IDEA onaPentium MMX that is 1:65 times faster than any previously known implementation on the Pentium. By parallelizing four IDEA's we reach an unprecedented 78 Mbits/s throughput per output block on a 166MHz MMX. In the light of rapidly increasing popularity ofmultimedia applications, causing more dedicated hardware to be built, and observing that most of the current block ciphers do not bene t from MMX, we raise the problem of designing block ciphers (and encryption modes) fully utilizing the basic operations of multimedia., |
