Abstract. The recently developed algebraic attacks apply to all keystream generators whose internal state is updated by a linear transition function, including LFSR-based generator...
A classical construction of stream ciphers is to combine several LFSRs and a highly non-linear Boolean function f. Their security is usually analysed in terms of correlation attack...
At Crypto 2008, Shamir introduced a new algebraic attack called the cube attack, which allows us to solve black-box polynomials if we are able to tweak the inputs by varying an ini...

Recently proposed algebraic attacks [2, 6] and fast algebraic attacks [1, 5] have provided the best analyses against some deployed LFSR-based ciphers. The process complexity is exp...
Cryptographic systems and protocols are the core of many Internet security procedures (such as SSL, SSH, IPSEC, DNSSEC, secure mail, etc.). At the heart of all cryptographic funct...
