S-Rough Recognition of Knowledge and General Threshold Encryption Authentication Scheme of Recognition Conclusion

This paper is the research of S-rough recognition theory engrafted with information security theory. By using of assistant set in S-rough sets, this paper gives S-rough recognition structure of knowledge: rough recognition on the upper knowledge family R⁺, rough recognition on the lower knowledge family R^-; gives S-rough recognition degree theorem and S-rough recognition dynamic characteristic theorem of knowledge. Engrafting information security theory with S-rough recognition theory, this paper presents a general threshold encryption authentication algorithm based on elliptic curve cryptosystem, gives encryption authentication of S-rough recognition
