GU Da-gang · Jiangxi kexue · 2010
By means of the analysis for the digital signature scheme with message recovery,based on the elliptic curve cryptosystem,one digital signature scheme with message recovery based on redundant function was proposed,and the correctness of this digital signature,the choice and security of redundant functions were analyzed.The analysis results show that by selecting the appropriate redundant functions,the scheme is correct and it has high reliability and security,when the message which needed to be signed is short,the scheme is effective.
