The growing market of WPAN has led to an increasingdemand of security measures and devices forprotecting the user data transmitted over the openchannels.Advanced Encryption Standards(AES)isthe basic security approach for WPAN.To meet thelow cost,low power feature and high security demandof WPAN,a low cost,high efficient AES coreis proposed in this paper.To achieve low cost,methods of integration and resource sharing are usedin designing a very low-complexity architecture,especially in(inverse)byte substitution(inv)SubBytes)modules and(inverse)mix column(inv)MixColumn)modules,etc.Further more,AESEncryptor and Decryptor is integrated into a fullfunctional crypto-engine.This very low-cost andhigh efficiency AES core of IEEE 802.15.4-2006 isdesigned and emulated on Xilinx FPGA.Simulationresults show that this kind of design can be used inresource critical applications,such as smart card,PDA and mobile phones.
The growing market of WPAN has led to an increasing demand of security measures and devices for protecting the user data transmitted over the open channels. Advanced Encryption Standards (AES) is the basic security approach for WPAN. To meet the low cost, low power feature and hi-h security demand of WPAN, a low cost, high efficient AES core is proposed in this paper. To achieve low cost, methods of interation and resource sharing are used in designing a very low-complexity architecture, especially in (inverse) byte substitution ((inv) SubBytes) modules and (inverse) mix column ((inv) MixColumn) modules, etc. Further more, AES Encryptor and Decryptor is integrated into a full functional crypto-engine. This very low-cost and high efficiency AES core of IEEE 802.15.4-2006 is designed and emulated on Xilinx FPGA. Simulation results show that this kind of design can be used in resource critical applications, such as smart card, PDA and mobile phones.
