RC5-Based Security in Wireless Sensor Networks: Utilization and Performance
Information transferred in a wireless sensor network can be sensitive, hence it is vital to secure the data on the network. Enhancing the network's security affects the network operation, by increasing the data's handling time. In this paper, the trade-offs between enhanced security and sensor network performance is discussed. The studies concentrate on the increase in computation time and energy consumption as enhanced security features and levels are utilized. This paper presents RC5-based encryption and CMAC authentication, used to achieve data confidentiality, freshness, replay protection, authentication, and integrity.
