    abstract =  {This document discribles an Digital Signature Algorithm based on elliptic curves which is invented by Xiaoyun Wang et al. This digital signature algorithm is published by Chinese Commercial Cryptography Administration Office for the use of electronic authentication service system. The document *** published by Chinese Commercial Cryptography Administration Office includes four parts: general introdocution, Digital Signature Algorithm, Key Exchange Protocol and Public Key Encryption Algorithm. This document only gives the general introduction and digital signature algorithm.},
