Two Efficient Outsourced ABS (OABS) Schemes Denoted By OABS-I And OABS-II To Build An Efficient Outsourced Verifying Protocol
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 11
Abstract
Attribute-based signature (ABS) facilitates revelry to mark a message with fine-grained access control over make out information. Particularly, in an ABS system, users get hold of their attribute private keys from an attribute authority, with which they can presently sign messages for any predicate fulfilled by their attributes. We first advise and formalize a new concept called Outsourced ABS, i.e., OABS, in which the computational overhead at user side is really concentrated through outsourcing concentrated computations to an untrusted signing-cloud service provider (S-CSP). In addition, we be relevant this novel paradigm to existing ABS schemes to decrease the difficulty.
