Embodiment Construction
[0023] figure 1 The method for generating the license file provided by the embodiment of the present invention is shown, including the following steps:
[0024] Step 101: Make a license template in line with the company's characteristics. The template includes company logo, product picture, product model, name, and corresponding storage function introduction;
[0025] Step 102: Combining the unique identifier of the storage product into a digital signature using an encryption algorithm. Preferably, the encryption algorithm is MD5 algorithm.
[0026] The unique identifier may be a combination of three identifiers: product name, device serial number, and functional identifier.
[0027] Step 103: Using a specific algorithm to split and assemble the digital signature into an N×N matrix.
[0028] There are many ways to split it into an N×N matrix. For example, the simplest method is to split the digital signature into N×N strings, and use these strings in any order as each eleme...

The invention provides a method for generating and validating a license. The method comprises the following steps of: A, combining unique identifiers of a storage product into a digital signature by using an encryption algorithm; B, splitting the digital signature to form an N*N matrix; C, providing the N*N matrix for a user; D, receiving a request which is input by the user to use a certain storage function, randomly generating M groups of line and column numbers, and prompting the user through a user interaction interface; and E, by using the encryption algorithm, combining the unique identifiers of the storage product into the digital signature by the hardware of storage equipment, splitting the digital signature to form the N*N matrix by using a specific algorithm, comparing character strings which are input by the user with elements at corresponding positions of a matrix which is generated by the hardware, and if the character strings accord with the elements, allowing the user to use corresponding storage functions.
Description
technical field [0001] The invention relates to the technical field of license authorization, in particular to a license generation and verification method and a storage device. Background technique [0002] Manufacturers usually use license authorization to control the scope of use of computer-related products and avoid abuse and malicious use. [0003] Enterprise-level large-scale storage products are usually software and hardware bundled products. At present, the main license authorization method is usually: the manufacturer generates a unique license number corresponding to each product before leaving the factory, and stores the license number in the Store the license number in the firmware of the product, and inform the user of the license number in some way (for example, print the license number on the CD-ROM package that comes with the product). When the user uses the storage product, the storage product management software prompts the user to enter the license numbe...
