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

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 present invention relates to the technical field of license authorization, in particular to a method of license generation and verification and a storage device. Background technique [0002] Manufacturers usually use licensing methods to control the scope of use of computer-related products to avoid abuse and malicious use. [0003] Enterprise-level large-scale storage products are usually software and hardware bundled products. The main license authorization method currently used is usually: the manufacturer generates a unique license number for each product before leaving the factory, and stores the license number in Store the product's firmware, and inform the user of the license number in some way (for example, print the license number on the CD package of the product). When a user uses a storage product, the storage product management software prompts the user to enter a license number, compares the license number entered by the user with the licen...
