摘要

Data security is an important issue in today's computer networks.Several emerging applications require secure data channels over opennetworks. At the same time, the bandwidth of data channels is rapidlyincreasing, as demonstrated by current ATM networks. In this scenario,data communication products now have to incorporate high-performancesecurity devices. This paper presents SCOB, a soft-core implementationof the Blowfish cryptographic algorithm. This soft-core is orientedtowards applications demanding a high throughput and exploits both thespatial and the temporal parallelism available in the Blowfishalgorithm. An ASIC implementation of SCOB in 0.7 μm two-metal layerCMOS technology, reaches up to 266 Mbps at 66 MHz, while an FPGAimplementation provided up to 40 Mbps at 10 MHz
