Motivated by privacy issues associated with dissemination of signed digital certificates, we definea new type of signature scheme called a ‘Universal Designated-Verifier Signature’ (UDVS). A UDVSscheme can function as a standard publicly-verifiable digital signature but has additional functional-ity which allows any holder of a signature (not necessarily the signer) to designate the...

In this study, average was determined using calculation method based on surrounding surface temperatures and view factors.

Braids groups provide an alternative to number theoretic public cryptography and can be implemented quite efficiently. The paper proposes five signature schemes: Proxy Signature, Designated Verifier, Bi-Designated Verifier, Designated Verifier Proxy Signature And Bi-Designated Verifier Proxy Signature scheme based on braid groups. We also discuss the security aspects of each of the proposed sch...

A new type of signature is presented in this paper, named adaptable group-oriented signature. In contrast with traditional group-oriented signature, the new one laid a strong emphasis on how to improve the signer’s efficiency. In fact, this new type of group-oriented signature can be seen as a type of designated verifier signature. In contrast with the ordinary designated verifier signature, it...
