Software method for intellectual property protection of embedded products

Abstract

The invention belongs to the field of information security technology, and particularly relates to a software method for intellectual property protection of embedded products. A centralized license server generates licenses in a batch centralized manner and then transmits the licenses to license distribution tools, the license distribution tools distribute the licenses to the embedded products, record unique identifiers of the embedded products and the distributed licenses, store the both to a database and report the both to a license server on line, the license server records the binding relationships between the licenses and the unique identifiers of the embedded products reported by the license distribution tools, the embedded products judge whether the authorization verification passesby verifying whether the license information exists and whether the existing licenses are correctly matched with the unique identifiers of the embedded products, and the license server checks whetherthe unique identifiers of the on-line embedded products are matched with the licenses to strengthen the intellectual property protection. The software method does not need to use an encryption chip,saves hardware pins, and can centrally produce and manage, trace and monitor the licenses.

Description

technical field [0001] The invention belongs to the technical field of information security, in particular to a software method for embedded intellectual property protection. Background technique [0002] For embedded products currently on the market, the software on storage devices can basically be copied in binary form and programmed to another storage device. [0003] In order to protect the intellectual property rights of the product developer and prevent the original software from being copied while the hardware is copied, the following methods are mainly adopted in the industry: [0004] (1) Using encryption chips, the product owner or authorized manufacturer burns and writes the encryption chips before the product is produced, and writes a different license in each encryption chip. The encryption chip is soldered to the product during production. When the product is started, it is judged whether the encryption chip can be read correctly and whether it contains the co...

AI Technical Summary

Problems solved by technology

[0006] The protection method of the encryption chip has natural limitations, high hardware cost, occupying precious hardware pin resources, low efficiency, error-prone, difficult to achieve anti-copy, difficult to maintain, etc.

[0007] The software protection method needs to generate a license for each embedded product separately, and it takes a lot of time to write the license to the embedded product. In the case of multiple workstations or multiple factories to write the license , the license is also difficult to achieve centralized management
