A Comment to the Intelligent Functions of Different Weight Ciphers

Abstract

For different kinds of scale networks, the different weight ciphers should be designed for adapting various operation environments. In wireless networks or RFID environment, the lightweight ciphers or ultra-lightweight ciphers have been paid more and more attention. At Internet environment, there exist some block cipher algorithms used in top layer but not published block ciphers announce to only design for the other layers. The standardized security protocols of block cipher are oriented to the public level which is seldom considered based on different secure situation in openness Internet environment. And in trusted platform, some modules still need heavy ciphers.  So this paper’s approach is that it needs precise cryptographic system according to different networks and different functions. The scalable and flexible block cipher application is another approach to currently secure standard and the lightweight block cipher design should be paid more attention. In order to expending networks member number easily, some intelligent functions are combined in the design.
