An Attribute-Based Signature using rivest shamir adleman scheme

Attribute-Based Signature (ABS) system is a signature based system of cryptography in which the signer of the message does not need to be identified by his signature but by some attributes that are peculiar to the individual who is sending the message. In this paper, an ABS was designed based on groups having bilinear pairings with a dominant trait or attribute that can be readily used in a multi-authority situation. It had been able to prove that the construction is secure in the standard model. Finally, several applications of this new tool have been illustrated.
