With the prevalence of the Internet, World Wide Web emerged, creating e-commerce era, the rise of commercial transactions, and otherwise must rely on electronic documents and digital signatures to establish their rights and obligations, authenticity of information, authenticity and non-repudiation is provided by the electronic signature function, digital signature technology affect the development of e-commerce. This paper is to study fast computing based on elliptic curve cryptosystem, computational efficiency than other existing public key algorithm quickly, and make multiple copies of documents used a signcryption method of application, this method can significantly reduce the number of commercial paper encryption and signature, to enhance the efficiency of the benefits of reduced operating time. |
