LEAP: Efficient Security Mechanisms for Large-scale Distributed Sensor Networks

by Sencun Zhu , 2003
"... Protocol), a key management protocol for sensor networks that is designed to support in-network processing, while at the same time restricting the security impact of a node compromise to the immediate network neighborhood of the compromised node. The design of the protocol is motivated by the observ ..."

by the observation that different types of messages exchanged between sensor nodes have different security requirements, and that a single keying mechanism is not suitable for meeting these different security requirements. LEAP supports the establishment of four types of keys for each sensor node – an individual key

SPINS: Security Protocols for Sensor Networks

by Adrian Perrig, Robert Szewczyk, Victor Wen, David Culler, J. D. Tygar , 2001
"... As sensor networks edge closer towards wide-spread deployment, security issues become a central concern. So far, the main research focus has been on making sensor networks feasible and useful, and less emphasis was placed on security. We design a suite of security building blocks that are optimized ..."

Certification of Programs for Secure Information Flow

by Dorothy E. Denning, Peter J. Denning , 1977
"... This paper presents a certification mechanism for verifying the secure flow of information through a program. Because it exploits the properties of a lattice structure among security classes, the procedure is sufficiently simple that it can easily be included in the analysis phase of most existing c ..."

Security mechanisms in high-level network protocols

by Victor L. Voydock, Stephen, T. Kent - ACM Computing Surveys , 1983
"... The implications of adding security mechanisms to high-level network protocols operating in an open-system environment are analyzed. First the threats to security that may arise in such an environment are described, and then a set of goals for communications security measures is established. This is ..."

A Sense of Self for Unix Processes

by Stephanie Forrest, Steven A. Hofmeyr, Anil Somayaji, Thomas A. Longstaff - In Proceedings of the 1996 IEEE Symposium on Security and Privacy , 1996
"... A method for anomaly detection is introduced in which "normal" is defined by short-range correlations in a process ' system calls. Initial experiments suggest that the definition is stable during normal behavior for standard UNIX programs. Further, it is able to detect several common ..."

intrusions involving sendmail and lpr. This work is part of a research program aimed at building computer security systems that incorporate the mechanisms and algorithms used by natural immune systems. 1 Introduction We are interested in developing computer security methods that are based on the way natural

The Ponder Policy Specification Language

by Nicodemos Damianou , Naranker Dulay , Emil Lupu , Morris Sloman - LECTURE NOTES IN COMPUTER SCIENCE , 2001
"... The Ponder language provides a common means of specifying security policies that map onto various access control implementation mechanisms for firewalls, operating systems, databases and Java. It supports obligation policies that are event triggered conditionaction rules for policy based management ..."

Public-key cryptosystems based on composite degree residuosity classes

by Pascal Paillier - IN ADVANCES IN CRYPTOLOGY — EUROCRYPT 1999 , 1999
"... This paper investigates a novel computational problem, namely the Composite Residuosity Class Problem, and its applications to public-key cryptography. We propose a new trapdoor mechanism and derive from this technique three encryption schemes: a trapdoor permutation and two homomorphic probabilist ..."

Keying hash functions for message authentication

by Mihir Bellare, Ran Canetti, Hugo Krawczyk , 1996
"... The use of cryptographic hash functions like MD5 or SHA for message authentication has become a standard approach inmanyInternet applications and protocols. Though very easy to implement, these mechanisms are usually based on ad hoc techniques that lack a sound security analysis. We present new cons ..."

Random Key Predistribution Schemes for Sensor Networks”,

by Haowen Chan , Adrian Perrig , Dawn Song - IEEE Symposium on Security and Privacy, , 2003
"... Abstract Efficient key distribution is the basis for providing secure communication, a necessary requirement for many emerging sensor network applications. Many applications require authentic and secret communication among neighboring sensor nodes. However, establishing keys for secure communicatio ..."

Second, we propose a new
