New Block Ciphers for Wireless Moblile Netwoks

摘要

Wireless Mobile Networks (WMNs) play a fundamental role in the activities of each individual and organization. However, they have a number of limitations about hardware resources, processing capacity of the network devices. Hence, when integrating the cipher algorithms into the devices, the algorithms will have to be sure to reach high efficiency (fast processing speed and little resource expenses). This paper will demonstrate some results of constructing a new algorithm of cipher blocks based on the controlled element F_(2/2). This is the controlled element which has been studied and proved to be suitable for developing the algorithms of block ciphers with highly integrated speed and efficiency on the hardware platform VLSI. Therefore, this algorithm will be sure to work effectively and suitable for transmitting secretly on WMNs. Furthermore, this paper will also propose the schedule which creates the on-the-fly key to counteract the attacks of the related key. Usage of this key schedule will still ensure high efficiency when integrating the cipher algorithms on WSNs.
