A certificate issued by a user u for another user v enables any user that knows the public key of u to obtain the public key of v. A certificate dispersalD assigns a set of certificates D.u to each user u in the system so that user u can find a public key of any other user v without consulting a third party. In this paper, we present a stabilizing certificate dispersal protocol that tolerates transient...
We present a file search algorithm that is not only Sybil-resilient, but also load-balanced among users. We evaluate our algorithm in terms of bandwidth consumption and the likelihood of bad downloads. In both metrics, our algorithms show balanced overhead among users and small chances of bad download with low bandwidth consumption.
The notion of "session" created a considerable debate in access control. Recent research demonstrated that many access control constraints can not be verified statically at design time. The user behavior during an active session is uncertain, sessions are concurrent and some authorization decision parameters (i.e. conditions) are only available at runtime. However, similarly to what is done...
