specific Embodiment

[0030] Step 101, determine the current system date Time, this date needs to be accurate to the day, and the length is 16bit;

[0031] Step 102, determine a group of random number Random, be used for guaranteeing that serial number can not repeat, and length is 8bit; The length of this group of random number is longer than the length of keyword in a specific embodiment, and the longer random number encryption The better the effect. Random numbers can be generated using many existing random algorithms.

[0032] Step 103, combining Time and Random to obtain Keystr, which has a length of 24 bits;

[0033] Step 104, carry out XOR operation with the serial number of the software and the high 14bit of the Keystr obtained in step 103, the obtained value is Option, and the length is 14bit;

[0034] Step 105, carry out XOR operation with the version code of the software and the next highest 6bit of the Keystr obtained in step 103, and obtain a value of Product with a length of 6bit; ...

Abstract

The invention provides a serial number generation and verification method, which includes determining a group of random numbers and key numbers, and combining them into the first group of keywords, the random numbers are not repeated; The XOR operation becomes the second group of keywords; the encryption algorithm is used to encrypt the first group and the second group of keywords to obtain the third group of keywords; the three groups of keywords are combined into a plaintext sequence, and the distribution key algorithm is used to obtain The private key encrypts the plaintext sequence to obtain the serial number; the obtained serial number is verified. Compared with the prior art, this serial number generation verification method is relatively simple, and adopts a relatively safe encryption algorithm recognized by the public, and adds the use of a key, which can ensure the security of the serial number. Effectively guarantee the rights and interests of developers and consumers.

Description

technical field [0001] The invention relates to a data encryption method, in particular to a serial number generation verification method. Background technique [0002] Modern commercial software products are usually delivered as physical media containing the software code and an alphanumeric product key. It is common for software vendors to require their products to go through an "activation" process before treating specific users and computers with the full rights associated with the software. [0003] The serial number installation can effectively protect the software, so that the rights of developers and consumers can be guaranteed. Although there are many methods for generating and verifying serial numbers at present, most of them are complicated and not flexible enough. Moreover, the verification method is mostly one-time verification, which does not have the function of checking and updating. Contents of the invention [0004] The technical task of the present in...
