Authentication in Reprogramming of Sensor Networks for Mote Class Adversaries
Reprogramming is an essential service for wireless sensor networks. Authenticating reprogramming process is important as sensors need to verify that the code image is truly from a...

Establishing Pairwise Keys for Secure Communication in Ad Hoc Networks: A Probabilistic Approach
A prerequisite for secure communication between two nodes in an ad hoc network is that the nodes share a key to bootstrap their trust relationship. In this paper, we present a sca...

Diversify sensor nodes to improve resilience against node compromise
A great challenge in securing sensor networks is that sensor nodes can be physically compromised. Once a node is compromised, attackers can retrieve secret information (e.g. keys)...

Distributed Public-Key Cryptography from Weak Secrets
Abstract.We introduce the notion of distributed password-based publickey cryptography, where a virtual high-entropy private key is implicitly dened as a concatenation of low-entrop...

Some Remarks on Protecting Weak Keys and Poorly-Chosen Secrets from Guessing Attacks
Authentication and key distribution protocols that utilize weak secrets (such as passwords and PINs) are traditionally susceptible to guessing attacks whereby an adversary iterate...
