Revocable attribute-based encryption (RABE) provides greater flexibility and fine-grained access control for data sharing. However, the revocation process most RABE schemes today is performed by cloud storage provider (CSP). Since CSP an honest curious third party, there no guarantee that plaintext corresponding to new ciphertext after same as original data. In addition, suffer from issues related key escrow. To overcome aforementioned issues, we present efficient scheme supports integrity...
Abstract Hedged public-key encryption (HPKE), introduced by Bellare et al. (ASIACRYPT 2009), provides useful security when the per-message randomness fails to be uniform due faulty implementations or adversarial actions. The HPKE scheme achieves IND-CPA (chosen plaintext attack) they used is of high quality, but, poor rather than breaking completely, it a weaker but notion called IND-CDA distribution as long message and together have sufficient min-entropy. However, little research on in...
Distributed networks remarkably enhance the convenience of network connectivity. How to achieve efficient cooperative computation while preserving data privacy is a challenge in scenario distributed networks. Secure computation, as key technology information security and protection networks, attracts more attention. In paper, we develop protocols secure two-party presence malicious adversaries which are constructed with homomorphic probabilistic cryptosystem, propose four honest-verifier...
Abstract Lossy trapdoor functions (LTFs), introduced by Peikert and Waters (STOC’08), have already been found to be a very useful tool in constructing complex cryptographic primitives black-box manner, such as one-way functions, deterministic public-key encryption, CCA-secure etc. Due the existence of side-channel attack, leakage information lossy function systems can lead impossibility provable security. Recently, Zhang et al. model consecutive continual leakage-resilient updatable (ULTFs)...
In recent years, with the intensification of market competition, more and firms tend to use gift cards promotion. this paper, we consider a retailer offers consumers, assume that demand is deterministic, then, linear function describe retailer's in condition no card promotion offering Finally, establish maximized profit derive optimal solution, so obtain firm's pricing, ordering policies. The analysis shows programs can result substantial increases depending on three important factors -...

Deterministic public-key encryption, encrypting a plaintext into unique ciphertext without involving any randomness, was introduced by Bellare, Boldyreva, and O'Neill (CRYPTO 2007) as realistic alternative to some inherent drawbacks in randomized encryption. Kiltz, Peikert Waters (EUROCRYPT 2012) bring deterministic encryption the identity-based setting, propose scheme (DIBE). Although construc- tions of chosen attack (CPA) secure DIBE have been studied intensively, construction (CCA) is...
