Intellectual property (IP) is a category of property that includes intangible creations of the human intellect. There are many types of intellectual property, and some countries recognize more than others. The most well-known types are copyrights, patents, trademarks, and trade secrets. Early precursors to some types of intellectual property existed in societies such as Ancient Rome, but the modern concept of intellectual property developed in England in the 17th and 18th centuries. The term "intellectual property" began to be used in the 19th century, though it was not until the late 20th century that intellectual property became commonplace in the majority of the world's legal systems.

A computer architecture, hardware modules, and a software method, collectively referred to as “EVISA,” are described that allow low-overhead multithreading program execution to be performed in such a way as to keep all processors usefully busy and satisfy real-time timing constraints. The architecture can be incorporated into the design of a multithreading instruction processor, or can be used as a separate architectural module in conjunction with pre-existing non-multithreading processors as well as specialized Intellectual Property (IP) core modules for embedded applications.

Software program module integrity detection method based on PKI public key algorithm

ActiveCN108667594AProtect intellectual propertyDoes not affect normal functionUser identity/authority verificationPublic key infrastructure trust modelsIntellectual propertyPublic key certificate

The invention discloses a software program module integrity detection method based on a PKI public key algorithm, and the method comprises the steps: carrying out the signing of a program module through a fixed certificate based on the PKI public key algorithm and a dedicated loading module; verifying module signature, loading a module, decrypting an imported table envelope, restoring an importedtable and starting a signature verifying thread of a code region during operation through comprising a fixed public key certificate, modulate signature and imported table digital envelope; entering anoriginal program inlet point for continuing the execution, wherein the secret keys employed during signing are consistent with the certificates employed during signature verification in a one-to-onemanner. The beneficial effects of the invention lie in that the method protects software from being tampered and used illegally under the condition that the normal function of the software is not affected, and also protects the intellectual property of a software owner.
