Security and privacy protection protocol based on edge computing in smart campus

Abstract With the continuous emergence of modern Internet of Things, mobile Internet and other new generation of campus information technology and its extensive application in professional campus education, the development of college professional campus education information construction has entered a new stage of development. In view of higher requirements on data storage and network transmission delay of core business system in smart campus and more prominent wireless network security problems, this paper proposes a privacy protection protocol for smart campus based on chaotic mapping and edge computing. The protocol uses chaos mapping algorithm to protect user identity and negotiate session keys, and introduces edge computing to process authentication information on the edge server, which reduces the pressure of the core network and improves the authentication efficiency. This paper proves the security of the protocol by using BAN logic and Scyther, and verifies that the protocol can resist known attacks by analysing informal security. Through performance analysis and comparison, the proposed protocol has obvious advantages in computation and communication overhead.
