Efficient implementation of cryptographically useful "large" boolean functions
Palash Sarkar, Subhamoy Maitra · IEEE Transactions on Computers · 2003
We present low cost hardware architecture for implementing state-of-the-art theoretical constructions of secure Boolean functions suitable for stream ciphers. Using a pipelined architecture, we show that it is possible to implement systems which use Boolean functions of a relatively large number of variables. Our architecture is reconfigurable and provide a universal circuit for a certain class of secure Boolean functions.
