Authenticated Encryption in WSN Using eSTREAM Ciphers

摘要

Wireless Sensor Networks are gaining popularity due their wide spread application areas especially military, biomedical and cooperate sectors. Secure and authentic data exchange for sensitive and critical applications is a basic need. European Union's project eSTREAM ciphers have identified set of software implement-able stream ciphers with efficiency and security comparable to AES. Integration of an authentication mechanism with these software implement able stream ciphers remained an open challenge. Situation is further aggravated once target application platform is resource constrained in terms of energy, processing power and memory as in the case of WSNs. In this research work we have analyzed known authenticated encryption mechanisms using eSTREAM ciphers and their implementation in resource limited WSN environment.
