WebDue to this, the blind signature scheme has blindness and unforgeability. 2 Related Work In 1982, Chaum [3] gave the rst blind signature scheme based on RSA [18] and later used the blind signature scheme to construct the rst electronic cash scheme in [4]. Assume that a user, called a recipient, wishes a signer to sign a message m WebJan 14, 2024 · Abstract. This paper proposes the first practical pairing-free three-move blind signature schemes that (1) are concurrently secure, (2) produce short signatures (i.e., three or four group elements/scalars), and (3) are provably secure either in the generic group model (GGM) or the algebraic group model (AGM) under the (plain or one-more ...

WebOct 1, 2016 · A practical group blind signature scheme for privacy protection in smart grid. Journal of Parallel and Distributed Computing, Volume 136, 2024, pp. 29-39. Show abstract. The leakage of privacy is one of the key factors to restrict the development of smart grid. Currently, research works of protecting privacy in smart grid mainly focused … WebFeb 24, 2024 · I will discuss later why RSA based blind signatures were still the right choice for VPN by Google One. RSA parameters, oversimplified (assume that these are chosen correctly): e = public exponent. d = private exponent (known by signing server) x^e^d == x (mod N) for all x in [0, N) Protocol: Notes: r must be relatively prime to N.
