Embodiment Construction

[0016] Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] For ease of understanding, the agreements involved in this application are first described as follows:

[0018] 1) permutation operation function (Per), which is defined as follows:

[0019] Suppose A and B are two binary numbers of length l, where

[0020] A=a 1 a 2 …a l ,a i ∈{0,1},i=1,2,...,l (1)

[0021] B=b 1 b 2 …b l ,b j ∈{0,1},j=1,2,...,l (2)

[0022] The Hamming weight wt(B) of B is m (0≤m≤l), and

[0023]

[0024]

[0025] in, To arrange A according to B, Per(A,B) is expressed as:

[0026]

[0027] 2) MixBits function, which is defined as follows

[0028] Z=Mixbits(X,Y)

[0029] ---------------------------------

[0030] Z=X;

[0031] for(i=0; i<32; i++){

Abstract

The invention discloses a bidirectional authentication method of a near field communication technology. The system comprises a real identity (ID) and a temporary identity (IDS) of a label held by thelabel and a back-end database together, and shared keys K1 and K2 of a current session, in addition, the label also needs to store a timestamp Tt required by authentication, and the back-end databasestores last and latest IDS and shared keys K1 and K2. The bidirectional authentication method has the advantages that the bidirectional authentication method for near field communication safety canbe provided, the safety of the bidirectional authentication method is proved through simple bit and exclusive OR operation without hash and other function encryption operation and BAN logic, bidirectional authentication can be achieved, and label anonymity, data integrity and confidentiality and non-traceability are guaranteed. Common attacks including denial of service attacks, asynchronous attacks, replay attacks, algebraic attacks and the like can be resisted. Compared with the traditional scheme, the protocol not only solves the security and privacy problems, but also reduces the calculation and storage cost.

Description

technical field [0001] The invention belongs to the technical field of Internet near-field communication, and in particular relates to a two-way authentication method of near-field communication technology. Background technique [0002] The Internet of Things is a large-scale network composed of the Internet and various information sensing devices, which has developed very rapidly in recent years. Near Field Communication (NFC) is one of the core technologies of the Internet of Things and is listed as one of the most promising technologies. NFC is a short-distance, high-frequency, non-contact automatic identification wireless communication technology. It uses 13.56MHz and the distance is less than 10cm. This is the development and breakthrough of radio frequency identification technology. At present, near-field communication technology has been widely used in electronic ticketing, Product anti-counterfeiting, smart locks and other fields. But the security problem, especial...
