With more and more enterprises sharing their sensitive data on cloud servers, building a secure cloud environment for data sharing has attracted a lot of attention in both industry and academic communities. In this paper, we propose a conjunctive precise and fuzzy identity-based encryption (PFIBE) scheme for secure data sharing on cloud servers, which allows the encryption of data by specifying...

Secure buildings are currently protected from unauthorized access by a variety of devices. Even though there are many kinds of devices to guarantee the system safety such as PIN pads, keys both conventional and electronic, identity cards, cryptographic and dual control procedures, the people voice can also be used. The ability to verify the identity of a speaker by analyzing speech, or speaker ...

Cloud computing provides elastic, scalable on-demand IT services for individuals and organizations. In the cloud computing, everything is as the service. Cloud clients enjoy convenience and efficiency service, but at the same time encounter new issues. Cloud clients needs to provide authentication information to access to service, which often contains a lot of sensitive information. The service...

—Many authors have emphasized the similarity between quantum logic and fuzzy logic. In this paper, we show that, in spite of this similarity, these logics are not identical. Speci cally, we show that while quantum logic has a special “square root of not” operation which is very useful in quantum computing, fuzzy logic lacks such an operation. I. SIMILARITY BETWEEN QUANTUM LOGIC AND FUZZY LOGIC ...
