Cryptanalysis of Optical Ciphers Integrating Double Random Phase Encoding With Permutation

IEEE Access, 2017
This paper presents the cryptanalysis of optical ciphers combining double random phase encoding with permutation techniques, and shows its vulnerability against plaintext attack regardless of the implementation order of the two procedures. The equivalent secret keys of both the combination fashions can be retrieved, instead of the recovery of random ...

Higher-order differences based research on comparison between type-1 generalized Feistel-SP network and Feistel-SPSP network

Tongxin xuebao, 2014
The powers against the higher-order differential cryptanalysis of the single-SP(substitution-permutation) model and the double-SP model are studied in the type-1 Feistel network by analyzing the growths of algebraic degrees.

МАТЕМАТИЧНА МОДЕЛЬ СИМТЕРИЧНОЇ КРИПТОГРАФІЧНОЇ СИСТЕМИ ЗАХИСТУ МОВНОЇ ІНФОРМАЦІЇ НА ОСНОВІ ДИФЕРЕНЦІАЛЬНИХ ПЕРЕТВОРЕНЬ

Кібербезпека: освіта, наука, техніка
Among known cryptographic systems, in practice, symmetric cryptographic systems are most often used to protect speech information. Such systems, when encrypting speech information, implement stream encryption of outgoing traffic.
