In a strong designated verifier signature with message recovery (SDVSWMR) scheme, only the designated receiver has the capability to recover and validate the message‐signature pair. In 2015, using the bilinear pairing, Islam and Biswas presented an SDVSWMR scheme (we call it: IsBi‐SDVSWMR) with non‐delegatability, which has better performance than other schemes in terms of communication and computation...
In designated verifier signature, only the designated verifier can confirm the validity of a signature and it is applied widely in many environments such as electronic voting. However, most of designated verifier signature schemes cannot distinguish the real signer when the signer and the designated verifier arises a dispute on a signature. In other words, most of existing designated verifier signature...
This Proxy signature has been one of the hot spot in cryptography research as it can delegate the signing right of the original signer to the proxy signer. Therefore, it is applied in many areas such as mobile networks, distributed systems, control systems and other some information systems. Recently, many proxy signature schemes with special properties have been proposed. However, most of them is...
