摘要: The Advanced Encryption Algorithm (AES) has been the most widely used symmetric block cipher technique for providing security to applications adopting Wireless Sensor Networks (WSN). In this paper, an efficient software implementation of AES algorithm is described running on application specific processor (ASIP) platform that developed use in low-power wireless sensor node designs with low memory requirements. Experimental results show up 46.3% reduction cycle count achievable through extensive code optimization. Hardware customization are proposed ASIP template further improve performance. gains include reductions 33.1% and 45.2% encryption decryption, respectively 21.6% memory.
