A calculus for cryptographic protocols: The spi calculus

by Martin Abadi, Andrew D. Gordon - Information and Computation , 1999
"... We introduce the spi calculus, an extension of the pi calculus designed for the description and analysis of cryptographic protocols. We show how to use the spi calculus, particularly for studying authentication protocols. The pi calculus (without extension) suffices for some abstract protocols; the ..."

Security and Composition of Multi-party Cryptographic Protocols

by Ran Canetti - JOURNAL OF CRYPTOLOGY , 1998
"... We present general definitions of security for multi-party cryptographic protocols, with focus on the task of evaluating a probabilistic function of the parties' inputs. We show that, with respect to these definitions, security is preserved under a natural composition operation. The definiti ..."

The Protection of Information in Computer Systems

by Jerome H. Saltzer, Michael D. Schroeder , 1975
"... This tutorial paper explores the mechanics of protecting computer-stored information from unauthorized use or modification. It concentrates on those architectural structures--whether hardware or software--that are necessary to support information protection. The paper develops in three main sections ..."

of protecting information in computers. Access The ability to make use of information stored in a computer system. Used frequently as a verb, to the horror of grammarians. Access control list A list of principals that are authorized to have access to some object. Authenticate To verify the identity of a person

Prudent Engineering Practice for Cryptographic Protocols

by Martin Abadi, Roger Needhamt - Proc. IEEE Computer Society Symposium on Research in Security and Privacy , 1994
"... We present principles for the design of cryptographic protocols. The principles are neither necessary nor sufficient for correctness. They are however helpful, in that adherence to them would have avoided a considerable number of published errors. Our principles are informal guidelines. They complem ..."

Fuzzy extractors: How to generate strong keys from biometrics and other noisy data. Technical Report 2003/235, Cryptology ePrint archive, http://eprint.iacr.org, 2006. Previous version appeared at EUROCRYPT 2004

by Yevgeniy Dodis, Rafail Ostrovsky, Leonid Reyzin, Adam Smith - 34 [DRS07] [DS05] [EHMS00] [FJ01] Yevgeniy Dodis, Leonid Reyzin, and Adam , 2004
"... We provide formal definitions and efficient secure techniques for • turning noisy information into keys usable for any cryptographic application, and, in particular, • reliably and securely authenticating biometric data. Our techniques apply not just to biometric information, but to any keying mater ..."

An Efficient Cryptographic Protocol Verifier Based on Prolog Rules

by Bruno Blanchet - IN 14TH IEEE COMPUTER SECURITY FOUNDATIONS WORKSHOP (CSFW-14 , 2001
"... We present a new automatic cryptographic protocol verifier based on a simple representation of the protocol by Prolog rules, and on a new efficient algorithm that determines whether a fact can be proved from these rules or not. This verifier proves secrecy properties of the protocols. Thanks to its ..."

Random key predistribution schemes for sensor networks

by Haowen Chan, Adrian Perrig, Dawn Song - IN PROCEEDINGS OF THE 2003 IEEE SYMPOSIUM ON SECURITY AND PRIVACY , 2003
"... Key establishment in sensor networks is a challenging problem because asymmetric key cryptosystems are unsuitable for use in resource constrained sensor nodes, and also because the nodes could be physically compromised by an adversary. We present three new mechanisms for key establishment using the ..."
Abstract - Cited by 813 (14 self) - Add to MetaCart
-reinforcement scheme, we show how to strengthen the security between any two nodes by leveraging the security of other links. Finally, we present the random-pairwise keys scheme, which perfectly preserves the secrecy of the rest of the network when any node is captured, and also enables node-to-node authentication

Ariadne: A secure on-demand routing protocol for ad hoc networks

by Yih-chun Hu , 2002
"... An ad hoc network is a group of wireless mobile computers (or nodes), in which individual nodes cooperate by forwarding packets for each other to allow nodes to communicate beyond direct wireless transmission range. Prior research in ad hoc networking has generally studied the routing problem in a n ..."

Secrecy by Typing in Security Protocols

by Martín Abadi - Journal of the ACM , 1998
"... We develop principles and rules for achieving secrecy properties in security protocols. Our approach is based on traditional classification techniques, and extends those techniques to handle concurrent processes that use shared-key cryptography. The rules have the form of typing rules for a basic co ..."

Data Security

by Dorothy E. Denning, Peter J. Denning , 1979
"... The rising abuse of computers and increasing threat to personal privacy through data banks have stimulated much interest m the techmcal safeguards for data. There are four kinds of safeguards, each related to but distract from the others. Access controls regulate which users may enter the system and ..."

Inference controls protect statistical databases by preventing questioners from deducing confidential information by posing carefully designed sequences
