Design and implementation of lightweight encryption and signature protocol for Universal Network

The identifier spoofing is a common threat problem which the access control protocol of Internet faces. In order to make sure that the identity of legal terminal avoids being spoofed, the identity can´t be imitated by third-party and the data packets between the terminal and Access Switching Router (ASR) should be added with a signature. In this paper, we design and implement a kind of signature mechanism in lightweight encrypted form to achieve security and efficiency purpose for the access control protocol in the Universal Network. The mechanism of the encryption to the communication between terminals and ASR in the way of adding an additional expansion header is the key point of this paper.
