Most modern Chip Multiprocessors (CMP) feature shared cache on chip. For multithreaded applications, the sharing reduces communication latency among co-running threads, but also r...
We consider the problem of threshold secret sharing in groups with hierarchical structure. In such settings, the secret is shared among a group of participants that is partitioned ...
We develop the foundations for a theory of Group-Centric Secure Information Sharing (g-SIS), characterize a specific family of models in this arena and identify several direction...
