Speculative execution has long been used as an approach to exploit instruction level par-allelism across basic block boundaries. Most existing speculative execution techniques only support speculating along single control path, and heavily rely on branch prediction to choose the right control path. In this paper, we propose an extended predicated execution mechanism, called predicate shifting, ...
Predicate encryption is a new encryption paradigm which gives a master secret key owner fine-grained control over access to encrypted data. The master secret key owner can generate secret key tokens corresponding to predicates. An encryption of data x can be evaluated using a secret token corresponding to a predicate f ; the user learns whether the data satisfies the predicate, i.e., whether f(...
In this paper, we focus on verifiability of predicate encryption. A verifiable predicate encryption scheme guarantees that all legitimate receivers of a ciphertext will obtain the same message upon decryption. While verifiability of predicate encryption might be a desirable property by itself, we furthermore show that this property enables interesting applications. Specifically, we provide two ...
