Cryptographic Signature Scheme for Mobile Edge Computing Using DLFP Over Semiring

Abstract

The Undeniable Signature Scheme (USS) was first introduced by Chaum and Van in 1989. The advantage of the (USS) scheme is the signer’s co-operation during the verification process. In this paper, the Discrete Logarithm Problem with Factor Problem (DLFP) is introduced. It’s security and complexity is analyzed. Then, based on (DLFP), a key exchange protocol is given. An undeniable signature scheme based on DLFP over semiring is proposed, with an illustration. Additionally, the application of the proposed USS in Mobile Edge Computing (MEC) is provided. Then the proposed scheme’s security and complexity are examined.
