Cryptanalysis of digital signature scheme based on error-correcting codes
Dian‐Wu Yue · Computer Engineering and Applications Journal · 2009
The existence of a security leak in a digital signature scheme proposed by Deng Yangming in 2003 is proved.It is shown that in this digital signature scheme anyone can obtain partial secret key just by resorting signatory’s public key,therefore,he may successfully forge a signature.Then it is pointed out that anybody can achieve partial secret key just by employing public key in the digital signature schemes whose design of public key is similar to the above proposed scheme.
