Abstract :
The Kasumi block cipher provides integrity and confidentiality services for 3G wireless networks, but it also forms a bottleneck due to its computational overhead. Especially in infrastructure equipment with data streams from multiple connections entering and leaving the network processor the critical performance issue needs to be addressed. In this paper we present a highly scalable bit sliced implementation of the Kasumi block cipher for the Intel IXP 28xx family of network processors. It can achieve a maximum theoretical encryption rate of up to 2 Gb/s when run in parallel on all 16 on-chip microengines
