DoS-Resistant Attribute-Based Encryption in Mobile Cloud Computing with Revocation
Security and privacy are very important challenges for outsourced private data over cloud storages. By taking Attribute-Based Encryption (ABE) for Access Control (AC) purpose we use fine-grained AC over cloud storage. In this paper, we extend previous Ciphertext Policy ABE (CP-ABE) schemes especially for mobile and resource-constrained devices in a cloud computing environment in two aspects, a ...
متن کاملArtemia: a family of provably secure authenticated encryption schemes
Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...

Definition of digital signatures. Recall that we had the following picture: Private Key Public Key Secrecy Private Key Encryption Public key Encryption Integrity Message Authentication Codes (MAC) ?? Digital signatures complete this picture by giving a public key analog of message authentication codes. Digital signatures were suggested by Diffie and Hellman in their seminal paper, but unlike th...
