Software verification method, software and hardware binding method and its programmable device

Abstract

Provided are a software verification method, a software-hardware binding method and a programmable device thereof. The software and hardware binding method includes: obtaining the identification of the designated hardware of the computing device that needs to be bound with the software to be released; generating a pair of public key and private key; solidifying the data about the public key in the programmable device; by using The private key digitally signs the identification of the specified hardware according to the digital signature algorithm to generate a digital certificate file, and distributes the digital certificate file together with the software.

Description

technical field [0001] The present application generally relates to the technical field of software and hardware protection of computing devices, and more specifically, relates to a software and hardware binding method, a software verification method and a programmable device thereof. Background technique [0002] At present, software and hardware manufacturers use various measures to protect the intellectual property rights of their own developed software and hardware. However, because the current software can run on devices developed by different manufacturers, the method based on software encryption is easy to be cracked, and after cracking, it is easy to be copied in large quantities, thereby causing huge economic losses to the manufacturer. [0003] Therefore, more and more manufacturers are now bundling software and hardware for sale, that is, binding hardware devices and corresponding software together so that the supporting software can only run on its corresponding ...

However, because the current software can run on devices developed by different manufacturers, the method based on software encryption is easy to be cracked, and after cracking, it is easy to be copied in large quantities, which will bring huge economic losses to the manufacturers.

[0003] Therefore, more and more manufacturers are now bundling software and hardware for sale, that is, binding hardware devices and corresponding software together so that the supporting software can only run on its corresponding hardware platform. However, the existing The software-hardware binding verification method is executed by the host running the software on the local CPU. For example, the verification public key of the digital signature algorithm must be stored on the local machine. However, it is precisely because the verification public key and other data are stored in the local CPU. Therefore, there is a possibility that the verification key is read or the key generation algorithm is cracked, and then the existing hardware-software binding verification method based on asymmetric key encryption may be cracked, or, in the future In the case of a substantial increase in computing power, the existing software-hardware binding verification method may also be cracked
