The focus of access control in client/server environments is on protecting sensitive server resources by determining whether or not a client is authorized to access those resource...
We present a model and protocol for anonymous credentials. Rather than using deterrents to ensure non-transferability, our model uses secure hardware with biometric authentication...
Randomization is vital in cryptography: secret keys should be randomly generated and most cryptographic primitives (e.g., encryption) must be probabilistic. As a bstraction, it is...
In the context of the security of wireless ad hoc networks, we previously explored the problem of secure transient association between a master and a slave device in the absence of...
By functionally decomposing a specific algorithm (the hierarchical secure aggregation algorithm of Chan et al. [3] and Frikken et al. [7]), we uncover a useful general functionali...
