Cryptanalysis of two schemes of Baba et al. by linear algebra methods
V. Roman'kov
We show that the attacks based on the linear decomposition method introduced by the author and the span-method introduced by Tsaban allow one to find the transmitted message in the…
Cryptographic analysis of the Modified Matrix Modular Cryptosystem
Vitaliĭ Roman'kov
We show that the Modified Matrix Modular Cryptosystem proposed by S.K. Rososhek is not secure against the attack based on the linear decomposition method. The security of the encry…
How to make RSA and some other encryptions probabilistic
Vitalii Roman'kov
A new scheme of probabilistic subgroup-related encryption is introduced. Some applications of this scheme based on the RSA, Diffie-Hellman and ElGamal encryption algorithms are des…
Linear decomposition attack on public key exchange protocols using semidirect products of (semi)groups
Vitaliĭ Roman'kov
We show that a linear decomposition attack based on the decomposition method introduced by the author works by finding the exchanged secret keys in all main protocols using semidir…
