A New Hill Cryptosystem With Digital Signature Function Base on The Problem of Matrix
In this paper,we have made improvement to the Hill cryptosystem based on the study of general inverse eigen-problem for matrix,then presented a new Hill cryptosystem with the digital signature function.we described the process of paper detailedly.The new Hill cryptosystem have the effect of higher security and stronger rigorous than paper[1].And also in this paper,we realized the key exchange protocols based on the ergodic matrix,which can avoid the reflex attack.At the same time,it can improve the efficiency of the scheme.
This paper presented a key distribution scheme based on the Yacobi scheme that does not use the secret key provided by key distribution center as a power, but uses instead a random number generated by the user. The scheme is independent of the exposure of the secret key. Then this paper described modified Diffie-Hellman schemes based on the discrete logarithm and prime resolution into factors. The modified DH scheme was applied to point-to-multicasting, and broadcasting networks via satellite.
