Silicon intelligent production area block chain authorization system and method thereof

Abstract

The invention discloses a silicon intelligent production area block chain authorization system and a method thereof. A purchase end host and an intelligent production end host which serve as nodes are provided in a block chain network, and when the purchase end host purchases silicon intelligent production from the intelligent production end host, the intelligent production end host encrypts the silicon intelligent production, embeds a tracking code, then transmits the encrypted silicon intelligent production to the purchase end host, issues a corresponding smart contract in the block chain network, and records a smart contract address and a tracking code; and when the purchase end host loads the encrypted silicon intelligent product, a corresponding intelligent contract address is queried according to the tracking code so as to execute an authorization function of the intelligent contract to obtain a decryption key, therefore, the encrypted silicon intelligent product can be decrypted and integrated into the integrated circuit design, and the technical effect of improving the right protection convenience and reliability of the silicon intelligent product can be achieved.

Description

technical field [0001] The present invention relates to an authorization system and method thereof, in particular to a silicon intellectual property block chain authorization system and method thereof. Background technique [0002] In recent years, with the vigorous development of the semiconductor industry, the use of Electronic Design Automation (EDA) tools to assist design, and the use of Silicon Intellectual Property (SIP) to speed up development, etc., have become the focus of various manufacturers. The norm when designing integrated circuits. [0003] Generally speaking, the so-called silicon intellectual property refers to the integration of pre-designed and verified silicon intellectual property into a System on a Chip (SoC) or a System in a Package (SiP) with required functions. ), the silicon intellectual property can be reused, for example, provided to chip design manufacturers in the form of Register Transfer Level (RTL). In this way, the situation of reinventi...

AI Technical Summary

Problems solved by technology

However, when the decryption key is leaked, this method cannot prevent unauthorized users from using the silicon intellectual property

In addition, this method cannot prevent authorized manufacturers from continuing to use silicon intellectual property when the number of authorizations is exceeded.

Therefore, the above-mentioned method still cannot effectively solve the problem of difficult maintenance of intellectual property rights of Silicon Intellectual Property

[0005] To sum up, it can be seen that there has been a problem that the intellectual property rights of silicon intellectual property are not easy to maintain in the existing technology for a long time, so it is necessary to propose improved technical means to solve this problem
