Security and Cryptography

2003
Writing secure code is hard. Even in traditional client-server applications, it’s difficult to defend against the vast array of possible threats and attacks. Security considerations stretch across every area of programming, from design to deployment, and include everything from hiding sensitive information to restricting the abilities of different ...

Cryptography architecture for information security

IBM Systems Journal, 1978
Information being transferred from point to point over a public communication carrier or stored on portable media can be protected, by the use of cryptography, from accidental or international disclosure. Control function are required to ensure synchronization of the process. In a communication environment, the control function become logically part of

The measure of security in quantum cryptography

2012 IEEE Global Communications Conference (GLOBECOM), 2012
This paper describes a new concept of security measurement in quantum cryptography (QC). The most popular quantum key distribution protocol BB84 and the key distillation process are briefly introduced first. Next, a new concept of entropy of security in QC is proposed, and a unique measure of security is defined.

Cryptography and Security

2010
In this chapter, we saw how to use the .NET cryptography features to perform common cryptographic operations, such as encryption, decryption, and hash code validation. The .NET Framework Class Library contains implementations of many encryption and has algorithms, some of which are implemented using underlying Windows features and others of which are ...

Cryptography, Capitalism, and National Security

IEEE Annals of the History of Computing, 2018
I call into question a line of thinking about the societal consequences of distributed network architectures. Empirically, this work centers its explanation on aberrant historical conditions, most notably the early Arpanet-centered Internet. Conceptually, despite an effort to identify a new order, it replicates foundational assumptions of exchange in ...

Cryptography Based Data Security

1990
Publisher Summary The chapter discusses the types of data security problems. The categories where data protections are falling are physical security, communication security, and operational security (database security, operating security, computer viruses).

The role of cryptography in database security

Proceedings of the 2004 ACM SIGMOD international conference on Management of data, 2004
In traditional database security research, the database is usually assumed to be trustworthy. Under this assumption, the goal is to achieve security against external attacks (e.g. from hackers) and possibly also against users trying to obtain information beyond their privileges, for instance by some type of statistical inference.

Security, Cryptography and Directed Bigraphs

2008
Bigraphical reactive systemsare an emerging graphical framework proposed by Milner and others [4,5,2,3] as a unifying theory of process models for distributed, concurrent and ubiquitous computing. A bigraphical reactive system consists of a category of bigraphs(usually generated over a given signature of controls) and a set of reaction rules.

Handbook of Financial Cryptography and Security

2010
The Handbook of Financial Cryptography and Security elucidates the theory and techniques of cryptography and illustrates how to establish and maintain security under the framework of financial cryptography. It applies various cryptographic techniques to auctions, electronic voting, micropayment systems, digital rights, financial portfolios, routing ...
