Unconditional Security in Quantum Cryptography [PDF]
Journal of the ACM, 2001 Basic techniques to prove the unconditional security of quantum crypto graphy are described. They are applied to a quantum key distribution protocol proposed by Bennett and Brassard [1984]. The proof considers a practical variation on the protocol in which the channel is noisy and photos may be lost during the transmission.

Security of neural cryptography
Proceedings of the 2004 11th IEEE International Conference on Electronics, Circuits and Systems, 2004. ICECS 2004., 2005In this paper we analyze the security of neural cryptography, a novel key-exchange protocol based on synchronization of neural networks. Various attacks on this protocol were suggested by Shamir et al., and the protocol was shown to be secure against them (Mislovaty et al. (2002)). A new attack strategy involving a large number of cooperating attackers,

Cryptography for Security in IoT
2018 Fifth International Conference on Internet of Things: Systems, Management and Security, 2018The Internet of Thing (IoT) has rapidly emerged as the manifesto of the Linked Society, where everything that benefits from a connection is connected. The IoT consists of multiple ecosystems, with different requirements and capabilities. There are few in the community who can escape IoT impact.

Cryptography and Future Security
Discrete Applied Mathematics, 2018Information Technology (IT) has been pervasive in our lives as an exciting paradigm with a user-centric environment to provide computing and communication services. IT advantages are realized in various computer science related environments such as cloud computing, ubiquitous computing, Internet of Things, and so on.

On securing untrusted clouds with cryptography
Proceedings of the 9th annual ACM workshop on Privacy in the electronic society, 2010In a recent interview, Whitfield Diffie argued that "the whole point of cloud computing is economy" and while it is possible in principle for "computation to be done on encrypted data, [...] current techniques would more than undo the economy gained by the outsourcing and show little sign of becoming practical".

Cryptography and Middleware Security
2001Middleware gives applications an abstract view of the underlying technology. Access control policies define the authorisations of principals. When no suitable representation of principals is available on the middleware layer, policies resort to using verifiable identifiers of underlying cryptographic mechanisms. However, this approach collides with the

Security of Quantum Cryptography
2020Quantum cryptography is one of the most mature area of quantum information. In the past few decades, active research has taken place in theoretical as well as implementation security of a practical quantum key distribution system. This resulted in hardening of theoretical proofs for a robust implementation against implementation loopholes and realistic

Cryptography and National Security
Information Systems Security, 1992This column addresses government policy issues that affect computer security. For good or for bad, government is increasingly involved with information systems in a variety of policy arenas, and computer security is an area that is attracting particular attention.

Unconditional Security in Cryptography
1999The fact that most presently- used cryptosystems cannot be rigorously proven secure and hence permanently face the risk of being broken motivates the search for schemes with unconditional security. The corresponding proofs however must be based on information theory rather than complexity theory. One reason for this is the lack of known lower bounds on

Secure Cryptography Infrastructures in the Cloud
2019 IEEE Global Communications Conference (GLOBECOM), 2019Information systems are deployed in clouds as virtual machines (VMs) for better agility, elasticity and reliability. It is necessary to safekeep their cryptographic keys, e.g., the private keys used in TLS and SSH, against various attacks. However, existing virtualization solutions do not improve the cryptography facilities of in-cloud systems.
