Identity-Based Signcryption from Identity-Based Cryptography

2012
A signcryption scheme encrypts and signs data in a single operation which is more efficient than using an encryption scheme combined with a signature scheme. Identity-based cryptography (IBC) does not require users to pre-compute key pairs and obtain certificates for their public keys.

Identity-Based Cryptography

2013
Since computer systems and communication become each time more pervasive, information security takes attention, requiring guarantees for data authentication, integrity and confidentiality. Pervasive communication and computer systems intend to provide access to information and services anytime and anywhere, demanding cryptographic systems more ...

Identity-Based Cryptography

2012
This chapter is devoted to giving a brief introduction to identity-based cryptography (IBC), which presents a nice solution for some problems that limit the wide deployment of public-key cryptography, in particular, the problem of binding public keys with user identities.

Electronic Voting Using Identity Based Cryptography

2010 Fourth International Conference on Digital Society, 2010
Today voting processes are the most important element of democracy as the society´s way to make decisions. Such processes have been influenced by information technologies until becoming be named electronic voting. This topic has been an active research area, on which, cryptographic primitives are used in order to propose secure protocols.

Simple Identity-Based Cryptography with Mediated RSA

2003
In this paper, we present a general framework for evaluating the performance characteristics of block cipher structures composed of S-boxes and Maximum Distance Separable (MDS) mappings. In particular, we examine nested Substitution-Permutation Networks (SPNs) and Feistel networks with round functions composed of S-boxes and MDS mappings.

ZigBee Security Using Identity-Based Cryptography

2007
ZigBee is a specification defining a set of protocols and architecture for monitoring and control networks. With the advantages of high availability, low cost and low power consumption, ZigBee is ideal for both residential and industrial settings. This paper proposes an application of identity-based cryptography for security in ZigBee networks.

Cloud Access Secure with Identity Based Cryptography

2015
With the fast evolution of networks and Internet, appeared the concept of the Cloud, the requirements in terms of safety become more and more essential. This requires the introduction of advanced authentication methods, access control and identity management, while respecting the constraints of the services offered by this evolution, such as data ...

Identity-Based Cryptography for Securing Mobile Phone Calls

2009 International Conference on Advanced Information Networking and Applications Workshops, 2009
In this paper, an identity-based key agreement system for mobile telephony in GSM and UMTS networks is presented. The use of telephone numbers as public keys allows the system to piggyback much of the security overhead for key management to the existing GSM or UMTS infrastructure.

Applicability of identity-based cryptography for disruption-tolerant networking

Proceedings of the 1st international MobiSys workshop on Mobile opportunistic networking, 2007
Traditional approaches for communication security do not work well in disruption- and delay-tolerant networks (DTNs). Recently, the use of identity-based cryptography (IBC) has been proposed as one way to help solve some of the DTN security issues. We analyze the applicability of IBC in this context and conclude that for authentication and integrity ...

Pseudonym management using mediated identity-based cryptography

Proceedings of the 2005 workshop on Digital identity management, 2005
Mobile Location-Based Services (LBS) have raised privacy concerns amongst mobile phone users who may need to supply their identity and location information to untrustworthy third parties in order to access these applications. Widespread acceptance of such services may therefore depend on how privacy sensitive information will be handled in order to ...
