Cryptographic Hash function is perhaps the most versatile cryptographic algorithm, it is widely used in a variety of security applications and network protocols. It has been widely used mainly in the digital signature, authentication and other fields. MD5 algorithm is one of the Hash function algorithm. MD5 algorithm is a typical representative of the MD… (More)
In this paper, fuzzy control theory technology and DSP technology are appLied to colLiery gas detection system. An intelLigent gas density fuzzy controller is designed, which improves the performance of this system in intelLigence, automation, precaution and fight natural calamities, production safety, control accuracy and safe reLiabiLity.
