Magic square signature method for true or false identification

Abstract

A method of using magic square signature to identify true or false of status includes generating a magic square for each article, adding elements of generated magic square on elements of signature magic square to achieve model for obtaining a signature matrix and using this matrix as identification data of article status, sending signature matrix to identifying device with signature magic square for calculating model difference of said matrix to signature magic square and verifying whether matrix is magic square or not, confirming that status having signature matrix is true or otherwise it isfalse if matrix is magic square.

Description

technical field [0001] The present invention relates to a magic square signature method for identity authenticity identification, in particular to a two-way dynamic authentication method of identity which is composed of magic square signature, encryption and card shuffling methods, and the registration information can be made public, and an encoding algorithm The magic square digital anti-counterfeiting method that can be made public with the database. technical background [0002] Identity authentication is the primary link in the network information security system and the basis of e-commerce and e-government. The general principle of identity authentication is to compare some special information or computing ability provided by the authenticated party with the corresponding information or ability held by the verifier. There are many methods of network identity authentication, the most commonly used one is to combine the user account and password, first use the account to...

Problems solved by technology

However, the RSA public key cryptosystem has the following disadvantages: 1) It is very troublesome to generate the key, and it is difficult to achieve one-time encryption due to the limitation of the prime number generation technology; 2) The block length is too large. In order to ensure security, the block length must be at least More than 600bits, the calculation cost is too high, especially the speed is slow, several orders of magnitude slower than the symmetric encryption algorithm; and with the development of large number decomposition technology, this length is still increasing, the encryption efficiency will decrease, and it is not conducive to the data format 3) There are chosen ciphertext attack methods and public modulus attack methods for RSA; 4) Although the public key can be disclosed, it is easy to be exchanged, and the confirmation of the public key requires a complex authentication system

The magic square digital anti-counterfeiting method has the advantages of open coding algorithm, open anti-counterfeiting database, independent anti-counterfeiting code, two-way anti-counterfeiting, and easy implementation. The anti-counterfeiting code of the magic square signature can be generated privately
