Digital Certificate of Public Key for User Authentication and Session Key Establishment for Secure Network Communications
摘要
In an insecure network environment, public key authentication in sending information is an important security challenge for user authentication. Many schemes based on cryptography have been proposed to solve the problem. However, previous schemes are vulnerable to various attacks and are neither efficient. Therefore, whereby needs more research; Therefore, Standard Digital Certificate Mechanism (SDCM) is an important primitive idea for authenticated key agreement. The (SDCM) is one of the simplest and the most convenient authentication mechanisms, which is more frequently required over insecure areas, such as computer and wireless networks, remote login, operation systems, and database management systems. The (SDCM) contains some user's public information, such as the information of user authentication's digital, the information of a digital birth certificate, general credentials (certificates), a digital signature of public information signed by a (CA), etc. Therefore must make design decisions that appear well-motivated but have unintended consequences, based on this concept, we propose user secure mutual authentication and session key establishment protocol based on combining the discrete logarithm (DL) problem, the Diffie-Helman assumption (DHA), and the one-way hash function to withstand the well-known attacks and to keep the same merits.
