A wireless security authentication method based on a block chain technology

Abstract

The invention discloses a wireless security authentication method based on a block chain technology, which utilizes a consensus mechanism combining workload proof and longest chain extension to recorduser information generation transactions in a non-tamper and decentralized block chain account book, and designs user registration phase and user login and authentication phase protocols respectively. Distributed Denial of Service (DDoS) attacks and other common attacks can be effectively avoided, so that users can safely identify network equipment in the wireless network environment, and not beattacked by malicious users. And use less computation, can effectively reduce the cost of computing overhead.

Description

technical field [0001] The present invention relates to information security technology, in particular to a wireless security authentication method based on block chain technology. Background technique [0002] With the rapid development of information security technology and wireless network equipment, users can freely access the network through wireless network equipment. However, with the openness of wireless networks, the network environment is full of uncertainties, and insecure factors such as various network attacks and camouflage methods also follow. Network security issues are getting more and more attention. The first line of defense to ensure network communication and data security is to be able to accurately identify users among many wireless network devices. Identity authentication is the basis of information security in network systems. [0003] In 1981, Lamport first proposed a password authentication scheme, which solved the security problem of communicati...

Problems solved by technology

[0003] In 1981, Lamport first proposed a password authentication scheme, which solved the security problem of communication in an insecure channel. However, this scheme has some disadvantages: (1) It cannot resist replay attacks; (2) The calculation amount of Hash is relatively large. Big

In 2011, Khan et al. analyzed the scheme of Wang et al., and found that users cannot choose passwords freely, smart cards cannot be logged out after being stolen or lost, and cannot resist internal attacks.

[0006] Aiming at the security problems existing in traditional identity authentication, the present invention proposes a wireless security authentication method based on block chain technology. Since block chain has the advantages of decentralization, point-to-point transmission, consensus mechanism and cryptography technology, it can ensure user information storage In the blockchain distributed ledger, it will not be tampered with or lost
