| Description |
In this paper, a VLSI implementation for the SAFER+ encryption algorithm is presented. The combination of security, and high speed implementation, makes SAFER+ a very good choice for wireless systems. The SAFER+ algorithm is a basic component in the authentication Bluetooth mechanism. The relation between the algorithm properties and the VLSI architecture are described. The whole design was captured entirely in VHDL language using a bottom-up design and verification methodology. FPGA device was used for the hardware implementation of the algorithm. The proposed VLSI implementation of the SAFER+ algorithm reduces the covered area about 25 percent, and achieves a data throughput up to 320 Mbit/sec at a clock frequency of 20 Mhz.
