Efficient Identity Based Key Insulated Signature Schemes using Bilinear Pairins Over Elliptic Curves

Abstract

quotDigital signature schemes are one of the most important information newlinesecurity services offered by PKC. These schemes provide authentication, data newlineintegrity and non-repudiation to digital communications. By combining the newlineconcept of digital signatures with some specific protocols, some extensions or newlinevariations have been proposed during the last years, which a basic signature newlinescheme does not provide. Many specific realizations of these new types of newlinesignature schemes have been proposed in the traditional public key scenario. newlineIn recent years many ID-based cryptographic schemes, as an alternative to newlinetraditional PKC schemes especially where an efficient key management and newlinemoderate security are required, have been proposed using bilinear pairings such as newlineWeil and Tate pairings on elliptic curves over finite fields.quot newline newline
