Abstract: In order to overcome the problems of time-consuming and weak attack defence of traditional authentication methods, this paper proposes a new dynamic bidirectional authentication method for user identity in wireless sensor network based on DES algorithm. This method uses DES algorithm to complete the user identity information encryption at the client-side through three steps: initial transposition, encryption operation and final transposition of identity information. In view of the server transmission to obtain the challenge value, combined with the one-time password DES to distinguish the authenticity of the server, the user identity authenticity verification is completed. Through the client-side and server-side legitimacy verification, the dynamic bidirectional security authentication of user identity is realised. The experimental results show that the proposed method is efficient, and the security of identity authentication is stronger, which provides theoretical support for the research of related fields.
