Data Security in Wireless Sensor Networks – the Task for Public Key Cryptography
نویسنده
چکیده
The paper describes security algorithms and protocols provided by recent WSN stacks where symmetric-key schemes are commonly used. Using these schemes seems to be impractical in large scale networks; hence the paper intends their replacement by public-key schemes for mentioned low cost and low power MCU platforms. Moreover, the paper proposes implementation of Wireless Sensor Network (WSN) stacks embedded in common microcontroller (MCU) platforms – ARM7TDMI, x51, ColdFire, and HCS08 in order to compare it. Protocol stacks of proposed WSNs are based on the both – a proprietary and the ZigBee. Keywords—Elliptic Curve Cryptography, IEEE 802.15.4 Standard, Public Key Cryptography, Sensor Networks, ZigBee
