Rolf Höferthe boolean operations and most of the numeric operations in modern processors are T-functions, and their compositions are also T-functions. In earlier papers we considered ‘crazy’ T-functions such as .(.)= .+(.. ∨ 5), proved that they are invertible mappings which contain all the 2. possible states

Rolf Höfertinear cryptanalysis of stream ciphers based on the linear sequential circuit approximation of finite-state machines is introduced as a general method for assessing the strength of stream ciphers. The statistical weakness can be used to reduce the uncertainty of unknown plaintext and also to reconstr

Rolf Höfertcellular voice and data communication. The best published attacks against it require between 2. and 2. steps. This level of security makes it vulnerable to hardware-based attacks by large organizations, but not to software-based attacks on multiple targets by hackers..In this paper we describe new a

However, while a biased die may be a good source of entropy, many applications require input in the form of unbiased bits, rather than biased ones. In this paper, we present a new technique f

Rolf Höferted attack works against 6 out of the 8.5 rounds (in the non-related-key attacks model), employs almost the whole codebook, and improves the complexity of an exhaustive key search by a factor of only two. In a parallel way, Lipmaa demonstrated that IDEA can benefit from SIMD (Single Instruction, Mult
