Software security and software validity period verification method and system

Abstract

The invention discloses a software security and validity period verification method and system, and the method comprises the steps: obtaining hardware data of a host when software runs; encrypting the hardware data by adopting an encryption algorithm to obtain a first identification code and a first verification code corresponding to the first identification code; judging whether the first verification code is successfully matched with a pre-obtained target verification code or not; if yes, verification is passed, otherwise, dates D are traversed in a date set, the first identification code and the dates D are processed and then encrypted, a second verification code corresponding to each date D is obtained, D belongs to [D1, D2], D is a positive integer, D2 is larger than or equal to D1, D1 is the current date of the system, and D2 is the expiration date of the validity period of the software; judging whether a second verification code matched with the target verification code exists or not; if yes, determining that the verification is passed, and if not, determining that the verification fails. According to the method, additional encryption hardware is not needed, the cost is reduced, the period is short, and verification of software in environments such as medical scenes which cannot be connected with an external network is facilitated.

Description

technical field [0001] The invention relates to the technical field of software verification, in particular to a verification method and system for software security and software validity period. Background technique [0002] At present, in some scenarios that cannot be connected to the external network, such as hospital environments, the hardware verification method (dongle) is generally used for software security verification. This method must purchase hardware equipment, which increases the verification cost, and with the increase in sales volume , the cost of encryption hardware has increased dramatically. In addition, when the customer's encryption equipment is damaged or lost, additional encryption equipment needs to be purchased, which increases the maintenance cost, and the customer can only use it normally after a certain period, thereby reducing customer satisfaction. [0003] In the related art, for example, the invention patent application with the application n...
