On the Immunity of Rotation Symmetric Boolean Functions Against Fast Algebraic Attacks

Boolean functions are frequently used in the design of stream ciphers, block ciphers and hash functions. One of the most vital roles in cryptography of Boolean functions is to be used as filter and combination generators of stream ciphers based on Linear Feedback Shift Registers (LFSR). The study of the cryptographic criteria of Boolean functions is important because of the connections between known cryptanalytic attacks and these criteria. The class of rotation symmetric Boolean functions has been proven to be very useful in cryptography. This has led to many papers studying different cryptographic properties of rotation symmetric functions
