Method and system for encrypting software

Abstract

The invention provides a method and a system for encrypting software. The method comprises the following steps: writing software licensing information into the preserved storage space of a basic input / output system (BIOS) or an extensible firmware interface (EFI); when the software runs, obtaining the software licensing information from the preserved storage space; and detecting whether the software licensing information is right or not through the application program of the software; and if the software licensing information is right, the software normally runs, and otherwise, the software abnormally runs. By adopting the method and the system for encrypting the software, the software cannot be easy to crack, and the software encrypting safety is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of software encryption, in particular to a software encryption method and system. 【Background technique】 [0002] In order to prevent illegal copying and piracy of software and protect the interests of software developers, it is necessary to encrypt the software. At present, many anti-piracy software on the market are mostly single-machine processing, using simple encryption methods, which are easy to be cracked by decryptors. [0003] In addition, some of them are encrypted by means of hardware dongles. The dongle is an encryption product that is inserted into the parallel port (or USB interface) of a computer, which combines software and hardware. Generally, there are tens or thousands of bytes of non-volatile storage space for reading and writing. Currently, the commonly used encryption The dog also contains a microcontroller inside. Software developers use interface functions (API, Application Progr...

Problems solved by technology

If the dongle is not inserted into the parallel port (or USB interface) of the computer or the dongle does not correspond to the software, the software cannot run normally

[0004] However, encryption is realized by means of a hardware dongle. For software developers, a hardware dongle device is added to the system, which increases the cost, especially in mass production, and the cost will increase significantly; in addition, plug-in encryption The dongle is also easy to be lost or damaged, which leads to the paralysis of the entire system software; the plug-in dongle has poor stability and is prone to poor contact, especially in the case of harsh working environments, such as industrial control fields with relatively high shock resistance requirements. The type of dongle is bound to affect the stability of the entire system; and, although the current dongle anti-cracking technology is constantly improving, there are many ways to crack the dongle on the Internet, and the use of dongle encryption software reduces the encryption security of the system software. sex
