Improving the Fault-Tolerant Scheme Based on the RSA System
Huifang Xue · 2010
Fault tolerance and encryption are two key themes in modern communication systems. The author proposes an improved approach to integrate fault tolerance, encryption and digital signature. A pseudorandom permutation matrix is adopted to randomize the cipher matrix, forcing attackers to solve the homogeneous problem. The novel scheme is more secure against adaptive chosen ciphertext attacks than those available.
