A survey of key distribution in wireless sensor networks [PDF]
Security and Communication Networks, 2011 AbstractKey establishment is the most fundamental cryptographic primitive in all kinds of applications where security is a concern. However, the nature of limited resources on sensor nodes restricts the use of conventional key management techniques in wireless sensor networks.

Low-Energy Symmetric Key Distribution in Wireless Sensor Networks [PDF]
IEEE Transactions on Dependable and Secure Computing, 2011 In this work, a scheme for key distribution and network access in a Wireless Sensor Network (WSN) that utilizes Identity-Based Cryptography (IBC) is presented. The scheme is analyzed on the ARM920T processor and measurements were taken for the runtime and energy of its components.

Random key pre-distribution with transitory master key for wireless sensor networks [PDF]
Proceedings of the 5th international student workshop on Emerging networking experiments and technologies, 2009 Many Wireless Sensor Networks (WSNs) employ security schemes based on the symmetric encryption, which requires the establishment and management of cryptographic keys. This paper presents a new key management scheme based on Random Key Pre-Distribution. The novelty of the proposed approach is the introduction of a keyed transformation with a Transitory ...
