Cryptography and Middleware Security

2001
Middleware 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

2020
Quantum 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, 1992
This 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.

Management of security in quantum cryptography

IEEE Communications Magazine, 2013
The interest in quantum-based security methods has been growing rapidly in recent years. New implementations of quantum key distribution and new network services supported by this solution are being introduced. The reason behind the growing popularity of quantum cryptography is its unrivaled security level: all eavesdroppers can be revealed through the

Cryptography with information theoretic security

Proceedings of the IEEE Information Theory Workshop, 2003
Summary form only given. We discuss information-theoretic methods to prove the security of cryptosystems. We study what is called, unconditionally secure (or information-theoretically secure) cryptographic schemes in search for a system that can provide long-term security and that does not impose limits on the adversary's computational power.

Unconditional Security in Cryptography

1999
The 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

Security and Cryptography

2010
Prior to version 4.0, the .NET Framework incorporated two complementary security models that addressed user and code security: role-based security (RBS) and code access security (CAS). With version 4.0, CAS has been deprecated. The previous edition of this book included a number of CAS recipes (11-1 through to 11-7), and we have included them in this ...

Secure Cryptography Infrastructures in the Cloud

2019 IEEE Global Communications Conference (GLOBECOM), 2019
Information 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.
