The encryption and digital signature solve the problem in integrity and confidentiality of active code. The application of decode-binding realizes the scalability in systematic encryption methods.
For a cyclic code, it is difficult to find the set of it's covering polynomials. We have not had a systematic method to find it.
给定一个循环码，求取它的覆盖多项式集合目前尚无系统的方法。

It has been pointed out that the five-point method specified in the current code gives values with smallest errors, whereas markedly small systematic errors are found in relation to all other methods.
