Attribute-based signature (ABS) enables users to sign messages over attributes without revealing any information other than the fact that they have attested to the messages. However, heavy computational cost is required during signing in existing work of ABS, which grows linearly with the size of the predicate formula. As a result, this presents a significant challenge for resource-constrained devices...
Cloud computing is an emerging computing paradigm in which IT resources and capacities are provided as services over the Internet. Promising as it is, this paradigm also brings forth new challenges for security when users want to securely outsource the computation of cryptographic operations to the untrusted cloud servers. As we know, modular exponentiation is one of basic operations among most of...
The deniably information-hiding encryption (DIHE) is a type of deniable encryption which can hide an additional information in encrypting a normal message. Even if the sender or the receiver is coerced to show the plaintext and the random coins in the encryption, a DIHE scheme behaves like only an innocent message is encrypted. Because it protects privacy against malicious coercer, the DIHE scheme...
