Secure wireless communications among sensor nodes is critical to the deployment
of wireless sensor networks. However, resource limited sensor nodes cannot afford
complex cryptographic algorithms. In this thesis, we propose a low complexity and
energy efficient reconfigurable feedback shift register (RFSR) stream cipher, link layer
encryption framework RSec and authentication protocol RAuth.
RFSR adds one new dimension, reconfigurable cipher structure, to the existing
stream ciphers. The proposed RFSR is implemented on a field programmable gate
array platform. Simulation results show that much lower power consumption, delay and transmission overhead are achieved compared to the existing microprocessor
based cipher implementations. The RSec framework utilizes RFSR ciphers to guarantee message confidentiality. By comparing with other encryption frameworks in
terms of energy efficiency, RSec achieves the best benchmark. The RAuth protocol
is designed on top of RFSR and RSec. It provides excellent authentication speed and
security level by comparing with other authentication protocols. / Graduate / 0544 / 0984 / zggyzz@gmail.com
