dc.description.abstractCiphertext-Policy Attribute-Based Encryption (CP-ABE) is a promising cryptographic mechanism for fine-grained access control to shared data. Attribute/Key management is a keystone issue in CP-APE because of low efficiency of existing attribute revocation techniques. Indeed, existing solutions induce great side effect after each attribute revocation. The side effect induces rekeying and/or re-assignment of attributes to all users. In this paper, we propose a solution which does not require extra entities like proxies to re-encrypt data after every access policy change. Moreover, our solution does not imply latencies following access grants and revocations. We compare our solution with the batch-based CP-ABE attribute management technique and we show that our solution outperforms existing rekeying/revocation techniques in terms of overhead.fr_FR
