Abstract

The invention is applicable to the communication safety field and provides a software protection method, a device and equipment. The method comprises the following steps: current time information of an operation system which operates an encrypted software is obtained; an encryption algorithm in an algorithm unit which is corresponding to the obtained current time information is called from a hardware encryption lock, thereby obtaining a return value of the encryption algorithm; whether a software is protected or not is judged according to the return value of the encryption algorithm. The embodiment of the invention realizes the protection of the software and reduces the risk that communication information between the encrypted software and the hardware encryption lock is eavesdropped effectively by obtaining the time information of the operation system and calling the encryption algorithm which is corresponding to the time information from the hardware encryption lock.

Description

technical field [0001] The invention belongs to the field of communication security, and in particular relates to a software protection method, device and equipment. Background technique [0002] Hardware encryption lock (also known as hardware encryption card, commonly known as dongle) is an intelligent software protection tool provided for software developers. It is a special hardware installed on the parallel port or USB port of the computer. It includes a set of Language interface software and tool software. The hardware encryption lock is a hardware-based encryption technology, and its purpose is to encrypt and protect the software so that the software will not be used illegally. [0003] The process of encrypting and protecting the software with the hardware dongle is as follows: preset the corresponding relationship between the query value and the returned value. The application program interface (Application Program Interface, API) provided by the software through ...
