XDR data information encryption method, device and equipment, and medium

Abstract

The invention provides an XDR data information encryption method, an XDR data information encryption device, XDR data information encryption equipment and a medium. The method comprises the steps of forming an array to be encrypted through selecting a plurality of adjacent numbers; combining the last number of the array to be encrypted with one or the plurality of numbers adjacent to the last number to form a random seed value; combining the random seed value, an ECGI value and a date value to form an encrypted secret key, using the encrypted secret key to encrypt the numbers 0-N to acquire aciphertext, and acquiring a randomly sorted array according to the ciphertext; replacing the number of which the serial number is the number subtracting one from the number to be encrypted with the number to be encrypted, thus acquiring a reset array to be encrypted, rearranging the number positions according to a preset arrangement rule, and acquiring encrypted data information. According to thetechnical scheme provided by the embodiment of the invention, the crack difficulty of the ciphertext can be improved, and the modification cost of the application system can be reduced.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an XDR data information encryption method, device, equipment and medium. Background technique [0002] In the prior art, there are generally two methods for encrypting data. A kind of is common data encryption, and it specifically is: adopt general symmetric encryption algorithm such as AES (Advanced Encryption Standard, Advanced Encryption Standard), to MSISDN (Mobile Subscriber International ISDN / PSTN number, mobile subscriber international ISDN / PSTN number, wherein, ISDN is Integrated Services Digital Network, which is the abbreviation of Integrated Service Digital Network) and other XDR (External Data Representation, external data representation) sensitive information is encrypted to generate meaningless ciphertext in the form of: ZgPZrDBM / ue87cvdF1rbHg==. Another method is: Data Masking, which specifically includes: cloning sensitive data, mask conversi...

Problems solved by technology

[0003] However, the above two data encryption methods have disadvantages.

The disadvantage of ordinary data encryption is: once the password is leaked, all the information can be obtained. The encrypted information still contains more real information, and the leakage of real information will easily lead to the location of the user's mobile phone, which will bring certain security risk

The data masking method can easily lead to the same ciphertext for different data. For example, the ciphertexts of 13900000000 and 13911110000 are both 139****0000, which will cause errors in the data association operation.

[0004] In addition, ordinary data encryption causes the byte length of the generated ciphertext to be larger than the length of the original plaintext, which leads to the risk of modification of the existing data system and brings additional costs
