Information exchange approaches are still an important research issue in the network security, generation and sharing the secret session key is the important factor during the group key transfer protocols. In this paper, we propose a new approach for information exchange based on PGP protocol as behavior. The proposed approach aims to combine chaotic techniques and curve security features based on chebyshev polynomial and quadratic Bezier curve, respectively to improve NTRU algorithm to increase the security features in the session key transfer process and improve DES algorithm in the encryption process. The proposed approach adds more security levels In the case of confidentiality and authentication with acceptable results.
