The Application Of E-commerce In Digital Signature

The rapid development of Internet makes Electronic Commerce into a new business model.E-commerce from generation to up now.Although it is not a long time, its development is growing very rapidly. Prospects for the development of e-commerce and its impact has attracted world wide attention from government and business and active participation because of E-commerce trading platform and the virtual anonymity. The security issues become more prominent which electronic signature technology and the safe operation of E-commerce legislation provides important protection.Digital signature which is the most common, most mature technology and operational is the E-commerce and E-government. That is to say. It is the most strongest electronic signature method. The so-called "digital signature" is generated by a cryptographic code composed of a series of symbols and signatures electronic password to replace the written signature or seal. It uses standardized procedures and scientific methods used to identify the signer's identity and the contents of an electronic data recognition. It also proved that the original document whether changes in the transmission process in order to ensure the integrity of electronic document transmission, authenticity and non-repudiation. Development boom in E-commerce, E-commerce security has become a major bottleneck restricting the development of E-commerce. With the development of electronic commerce and network. Electronic exchange of funds have become increasingly frequent. Information on how to prevent forgery and deception become a very important issue. In computer communication systems, maintenance of the security of electronic documents has become a critical and very sensitive issue. For the protection of information security, digital signatures came into being which is one of the main he study of modern cryptography, Current research on the digital signature focal point is based on the digital signature public key cryptosystem. Improve the security of digital signatures, including technical measures, to determine the ownership of the right CA certificate is the key to solving E-commerce security issues. The digital signature (Digital Signatures) technology is to ensure the confidentiality of information transmission, data exchange integrity, non-repudiation of sending messages, trading the certainty of the identity of an effective solution for the importance of e-commerce security section.This dissertation analyzes the digital signature of the situation and development trend. Followed by a digital signature of related technologies, including digital signatures and digital signatures based on mathematical concepts. Thirdly, the analysis of large integer factorization of RSA-based signature scheme and the ElGamal discrete logarithm based signature scheme. Its signature program is based on public key system, the realization of the main public key cryptosystem thought DSA signature scheme and digital signature scheme. Finally, in the two math problems on the basis of the number of proposed new method is proposed based on different mathematical problem while a security problem and based on discrete logarithm problem of prime factorization digital signature scheme.
