TY: CONF T1 - Enhanced Chaotic Stream Cipher for WSNs A1 - Silva, Rui A1 - Crespo, R. A1 - Nunes, M. N2 - This paper presents a stream cipher named eLoBa - ''enhanced Lorenz Based'', for Wireless Sensor Networks. eLoBa presents considerable improvements to a recently proposed PRNG based on Chaos, that increases its performance and security namely against algebraic attacks. We describe the eLoBa architecture and evaluate its security and performance comparing eLoBa with AES in counter mode. We show that eLoBa requires less computing power being 40% faster then AES in counter mode. eLoBa also decreases the protocol overhead in the transport of IP packets in Wireless Sensor Networks.
