Abstract


With the deepening of the identity-based cryptography research , there has been a large number of identity-based cryptography protocol . Has been widely used in the authentication protocol between the server and the user , but the reality is there are requirements for authentication between the user and the user needs , such as battlefield IFF system . The main research is user identity-based authentication techniques. This article first discussed in detail the framework of the model and its security authentication system based on bilinear mapping . Subsequent assumptions and calculations based on discrete mathematics puzzles Diffie-Hellman difficult hypothesis is proposed use the bilinear maps constructed identity-based the authentication protocol PIBI, and prove the correctness of the protocol and security . Using the PBC function library , analysis of the specific implementation of the program by the computational efficiency of the PIBI protocol under safe working parameters . Then, the combination of the special applications of collaborative IFF system , the proposed authentication protocol is extended to the case of multiple credible center suitable for collaborative application environment of the IFF system , operating parameters and in accordance with these trusted center expanded the same whether or not points were elaborated . Finally, we discuss the certification program in the specific implementation process need further consideration , such as key management and application security . Authentication protocol proposed in the certification process does not need to directly transmit secret information held by the user , each certification interaction certification both introduced random number factor dynamic authentication , so the agreement can be non- authenticated session encrypted channel communication mode , saving the system overhead required to maintain the encrypted channel . To a certain extent , the proposed deployment symmetric key secondary key revocation to solve the inconvenience of identity-based cryptography key revocation difficult institutional weaknesses in the application .
