摘要: The issue of authenticity in data transfer is very important many communications. In this paper, we propose an improved version the visual digital signature scheme with enhanced security. improvement was made based on Yang's non-expansion cryptography technique and Boolean operations. security assured by K-SAT (3-SAT 4-SAT) NP-hard problem. This to compare existing which difficulty solving random OR Besides also efficient generating shares, compared where probability black shares high.
