Abstract-Within the hospital or extended care environment, there is an overwhelming need for constant monitoring of vital body functions and support for patient mobility. Tomorrow's biomedical networks will address these needs by incorporating new technologies like wireless sensor networks into their infrastructure. However, wireless transmission of sensitive patient data presents some obvious security concerns. In this paper we discuss these concerns and how they are addressed by existing systems. We also discuss issues that need further consideration, such as run-time composition of security services depending on the criticality of data transmitted along with a solution for practical sensor systems using TinyOS. Finally, we propose intrusion detection as a future research direction for biomedical sensor networks and we elaborate on the main components of such a system.

Abstract-Time synchronization is essential in wireless sensor networks as it is needed by many of the applications for basic communication. The inherent characteristics of sensor networks do not permit simply applying the traditional time synchronization algorithms. Therefore, many new time synchronization algorithms have been proposed and few of them have provided security measures against various degrees of attacks. In this paper, we review the most commonly used time synchronication algorithms and evaluate these algorithms based on factors such as their countermeasures against various attacks and the types of techniques used (cryptographic vs. statistical)

Abstract. In sensor networks, correct clocks have arbitrary starting offsets and nondeterministic fluctuating skews. We consider an adversary that aims at tampering with the clock synchronization by intercepting messages, replaying intercepted messages (after the adversary's choice of delay), and capturing nodes (i.e., revealing their secret keys and impersonating them). We present the first self-stabilizing algorithm for secure clock synchronization in sensor networks that is resilient to such an adversary's attacks. Our algorithm tolerates random media noise, guarantees with high probability efficient communication overheads, and facilitates a variety of masking techniques against pulse-delay attacks in the presence of captured nodes.
