Research And Application Of Elliptic Curve Cryptosystems In Data Encryption

Along with the information management system, material transmission involves in more and more secure question. The information security technology is paid attention. The research and application of password theory is the core domain in the information security technique.Elliptic curve cryptosystems is one kind of public key cryptosystems, which is carrying the security high. It also has high security, speed, and short key, and takes the resources few characteristics compared with the traditional algorithm. Security experts in and out of country have already paid attention to the elliptic curve cryptosystems.The article first discusses the research present situation, the significance of this topic and the cryptology outline, conducts the research to the correlation mathematics theory, it also discusses the elliptic curve fundamental operation and the elliptic curve cryptosystems, and has realized encryption/decipher in the assigned curve. Based on the Chengdu University of Technology cooperation project -- material sharing information management system, produced a mix encipherment scheme, safer and faster compared with the traditional mix encipherment scheme.This article obtains several results:1) Research and analysis the Elliptic curve cryptosystems.2) According to different requests from the project, this paper obtained several different scheme of mix encryption/deeipher, it also has finished the work of encryption/decipher by the precondition which secures the efficiency and security.
