Digital signature is commonly used for authentication of a user or data. In order to ensure the security of a signature scheme, it is important to design a signature scheme with a security proof. In 1999, Gennaro et al. and Cramer et al. respectively proposed practical and provably secure signature schemes under the standard assumption without the random oracle model. Since then, some provably secure signature schemes in the standard model were constructed, for example, Camenisch–Lysyanskaya… CONTINUE READING
