Ciphertext Policy Attribute-Based Encryption (CPABE) has been proposed to implement the attribute-based access control model. In CP-ABE, data owners encrypt the data with a certain access policy such that only data users whose attributes satisfy the access policy could obtain the corresponding private decryption key from a trusted authority. Therefore, CP-ABE is considered as a promising fine-g...

In this paper, we propose new non-monotonic attribute-based encryption schemes with compact parameters. The first three schemes are key-policy attribute-based encryption (KP-ABE) and the fourth scheme is ciphertext-policy attribute-based encryption (CP-ABE) scheme. • Our first scheme has very compact ciphertexts. The ciphertext overhead only consists of two group elements and this is the shorte...

In Ciphertext-Policy Attribute-Based Encryption (CP-ABE), a user’s decryption key is associated with attributes which in general are not related to the user’s identity, and the same set of attributes could be shared between multiple users. From the decryption key, if the user created a decryption blackbox for sale, this malicious user could be difficult to identify from the blackbox. Hence in p...

We present selected new results on strong interaction physics from the SLD experiment at the SLAC Linear Collider (SLC), symmetry tests of b bg vertex, the rate of secondary b b production via gluon splitting, the B hadron energy spectrum and rapidity correlations between identi ed charged hadrons. The parity violation in Z ! b bg decays is consistent with electroweak theory plus QCD. New tests...

We give a complete classification of free and non-free multiplicities on the A3 braid arrangement. Namely, we show that all free multiplicities on A3 fall into two families that have been identified by Abe-Terao-Wakefield (2007) and Abe-Nuida-Numata (2009). The main tool is a new homological obstruction to freeness derived via a connection to multivariate spline theory.

Vehicular Ad Hoc Network (VANET) is an important part of the modern intelligent transportation system, which can provide vehicle communication at a certain distance. More importantly, VANET route planning and autonomous driving for drivers by analyzing data. However, VANET’s data privacy security are huge challenge when serving drivers. In this paper, we propose data-sharing model (DSVN) that c...

We use administrative data from Florida to determine the extent to which participation in prison-based Adult Basic Education (ABE) improves post-release earnings and/or employment. Utilizing a comparison group of inmates who had similar TABE scores on prison entry and a rich set of conditioning covariates, we find no systematic evidence that ABE participation is associated with higher post-rele...

Dispatching and Control Cloud (DCC) is a cloud platform constructed by State Grid Corporation with the technology of computing. DCC has improved overall operation monitoring capabilities, smart level many other advantages power grid. However, development been hampered security privacy issues. Secure unified identity authentication, access control authorisation management are significant topics ...
