Hash function-based MH lightweight security authentication system and method

Abstract

The invention discloses a Hash function-based lightweight security authentication system. The system comprises an electronic tag, a background database and a tag reader, wherein the electronic tag internally stores an ID, can generate a random number i and performs encryption through an M-Hash function, and encrypted information is Hm(ID,i); the background server internally stores an ID' corresponding to the ID and can perform encryption through the M-Hash function to obtain encrypted information Hm(ID',i); and the tag reader is connected with the electronic tag and the background database to realize data transmission between the electronic tag and the background database. The invention furthermore provides a Hash function-based lightweight security authentication method. The method and the system have the characteristics that the information is encrypted, the protocol logic bit operation is reduced, low hardware resource demand is met, the impact resistance is good, the security is higher, the power consumption is low, the running efficiency is high, and the like.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things security, and in particular relates to an MH lightweight security authentication system and method based on a Hash class function. Background technique [0002] With the rise of the "Internet +" industry, the information industry has developed rapidly. In the field of Internet of Things information, RFID radio frequency identification systems have also been widely used, including some key areas, such as financial systems, technological military systems, and engineering building systems, so how to ensure the communication security of RFID systems is very important . [0003] The RFID system consists of three parts: tags, readers, and background databases. Among them, tags belong to external circulation equipment and are also the most frequent part of security vulnerabilities. Tags are further divided into passive tags and active tags, because passive tags have the characteristics of st...

Problems solved by technology

This makes passive tags the most widely used in RFID systems, but the hardware resources of passive tags are less, which also makes some security protocols with higher security levels unable to be applied to passive tags.

[0004] Although the existing lightweight security protocols have low requirements on hardware resources, these protocols still have defects in the face of security problems such as masquerading attacks, location attacks, replay attacks, asynchronous attacks, and DNS attacks.
