A Kind Of Improvement Based On Elliptic Curve Digital Signature Technology And Application

Due to the popularity of the Internet,information transfer rapidly,Today,how to ensure information security has became a hotspot in the field of information transmission.Elliptic curve with its high security intensity,short key length and high calculation efficiency,and low bandwidth requirements has been widely applied in various fields.Elliptic curve cryptography has many research emphases,and the digital signature process is one of the research directions.In the process of elliptic curve digital signature dot product design,mould multiplication and inverse mode and a series of problems,is the main research object.In modern complicated attack tools and means of attack,to provide adequate security,token authentication can be used to solve the security problems in the authentication system effectively as a new method.This paper used the addition and subtraction instead of point multiplication operationin the process of digital signature,after studying the classical algorithms based on the elliptic curve digital signature process,then put forward a new digital signature algorithm.And analyzed the algorithm on safety and verify.The algorithm was achieved by programming.Several other improved algorithm was programmed at the same time,the comparison was made to prove its efficiency.And then introduced the token authentication specific processes,at the same time compare the authentication process response code generation and password recovery,with the prototype of the elliptic curve encryption process analogy,combined with the digital signature process,designed a kind of based on elliptic curve digital signature and encryption process of identity authentication scheme.Programming to implement the authentication process,from actually verify the correctness of the algorithm.and theoretically proved it is safe.
