Identity based cryptography offers an extremely bright alternative to public key based cryptography in the grid computing scenario. A majority of the current security architecture for grid systems use public key infrastructure based security to authenticate grid members and to secure resource allocation to them. In this paper we present identity based cryptography for the grid architecture whic...

Identity-based cryptography has attracted attention in the cryptographic research community in recent years. Despite the importance of cryptographic schemes for applications in business and law, the legal implications of identity-based cryptography have not yet been discussed. We investigate how identity-based signatures fit into the legal framework. We focus on the European Signature Directive...

Information confidentiality is an essential requirement for cyber security in critical infrastructure. Identity-based cryptography, an increasingly popular branch of cryptography, is widely used to protect the information confidentiality in the critical infrastructure sector due to the ability to directly compute the user's public key based on the user's identity. However, computational require...

This paper provides an overview of elliptic curves and their use in cryptography. The focus of the paper is on the performance advantages obtained in the wireless environments by using elliptic curve cryptography instead of traditional cryptosystems such as RSA. Specific applications to secure messaging and identity-based encryption are also discussed. keywords: elliptic curves, wireless, Digit...

In this paper, we introduce how to use cryptography in network security and access control of an e-hospital. We first define the security goal of the e-hospital system, and then we analyze the current application system. Our idea is proposed on the system analysis and the related regulations of patients’ privacy protection. The security of the whole application system is strengthened through la...

The revolutionary impact offered by identity based cryptography is phenomenal. This novel mechanism was first coined by Adi Shamir in 1984. Since then, several identity based signature schemes were reported. But surprisingly, none of the identity based signature scheme is having the property of determinism and does rely on bilinear pairing. We think positively in answering this long standing qu...
