Abstract
Along with the prosperous developing and popularity of the mobile communication technology, the more advanced security is required in the communication system. In 3G mobile communication systems, more and more new services are provided, such as multimedia, interactive data transaction, electronic business and internet services, except for traditional voice service and data service. So how to guarantee the security of the information transmitted in the mobile communication system and the security of the network resources has become an urgent problem.
Within the security architecture of the 3GPP system there are two standardized algorithms: A confidentiality algorithm f8, and an integrity algorithm f9. Each of these algorithms is based on the KASUMI algorithm. The 3G core cryptographic algorithm: KASUMI algorithm was presented in the paper, including its principles and components. KASUMI is a block cipher that produces a 64-bit output from a64-bit input under the control of a 128-bit key. In this paper one FPGA Implementation of the KASUMI algorithm is presented.
