popup.description2
New efficient methods, techniques, and algorithms were provided for cryptographic analysis of contemporary symmetric and asymmetric cryptosystems; classes of secure and insecure ciphers were described in classical and quantum computational models with respect to dedicated cryptanalytical attacks; analytic upper bounds estimations were founded for differential probabilities of word-oriented SP-networks with respect to some algebraic operation over words; message subspaces propagation in AES-like block ciphers was researched; estimations for size of linear system in special form were generalized from point of view of solving algorithms with fixed error probability; such estimations can be used for proving security of word-oriented stream ciphers against correlation attacks; new generalized algebraic model of symmetric cipher was developed; it was proven, that known plaintext security problem for symmetric and endomorph ciphers are polynomial equivalent; so-called "kleptographic" techniques for trapdoor embedding into cryptoalgorithms were researched, as well as methods for provable security providing; new concept was proposed for cryptosystem based on trusted outer pseudo-random generator; new Diffie-Hellmann-based protocol with guaranteed kleptographic SETUP trapdoor absence was proposed5481
