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

A Security Architecture for Computational Grids

by Ian Foster , Carl Kesselman, Gene Tsudik, Steven Tuecke , 1998
"... State-of-the-art and emerging scientific applications require fast access to large quantities of data and commensurately fast computational resources. Both resources and data are often distributed in a wide-area network with components administered locally and independently. Computations may involve ..."

involve hundreds of processes that must be able to acquire resources dynamically and communicate e#ciently. This paper analyzes the unique security requirements of large-scale distributed (grid) computing and develops a security policy and a corresponding security architecture. An implementation

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 ..."

Basic concepts and taxonomy of dependable and secure computing

by Algirdas Avizienis, Jean-claude Laprie, Brian Randell, Carl Landwehr - IEEE TDSC , 2004
"... This paper gives the main definitions relating to dependability, a generic concept including as special case such attributes as reliability, availability, safety, integrity, maintainability, etc. Security brings in concerns for confidentiality, in addition to availability and integrity. Basic defin ..."

Multiparty unconditionally secure protocols

by David Chaum, Ivan Damgdr - In STOC ’88: Proceedings of the twentieth annual ACM symposium on Theory of computing , 1988
"... Under the assumption that each pair of participants em communieatc secretly, we show that any reasonable multiparty protwol can be achieved if at least Q of the Participants am honest. The secrecy achieved is unconditional, It does not rely on any assumption about computational intractability. 1. ..."

Language-Based Information-Flow Security

by Andrei Sabelfeld , Andrew C. Myers - IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS , 2003
"... Current standard security practices do not provide substantial assurance that the end-to-end behavior of a computing system satisfies important security policies such as confidentiality. An end-to-end confidentiality policy might assert that secret input data cannot be inferred by an attacker throug ..."

The Advantages of Evolutionary Computation

by David B. Fogel , 1997
"... Evolutionary computation is becoming common in the solution of difficult, realworld problems in industry, medicine, and defense. This paper reviews some of the practical advantages to using evolutionary algorithms as compared with classic methods of optimization or artificial intelligence. Specific ..."

Efficient dispersal of information for security, load balancing, and fault tolerance

by Michael Rabin - Journal of the ACM , 1989
"... Abstract. An Information Dispersal Algorithm (IDA) is developed that breaks a file F of length L = ( F ( into n pieces F,, 1 5 i 5 n, each of length ( F, 1 = L/m, so that every m pieces suffice for reconstructing F. Dispersal and reconstruction are computationally efficient. The sum of the lengths ..."

( F, 1 is (n/m). L. Since n/m can be chosen to be close to I, the IDA is space eflicient. IDA has numerous applications to secure and reliable storage of information in computer networks and even on single disks, to fault-tolerant and efficient transmission of information in networks, and to communi

Security without identification: transaction systems to make Big Brother obsolete

"... The large-scale automated transaction systems of the near future can be designed to protect the privacy and maintain the security of both individuals and organizations. DAVID CHAUM Computerization is robbing individuals of the ability to monitor and control the ways information about them is used. A ..."

A Digital Signature Scheme Secure Against Adaptive Chosen-Message Attacks

by Shafi Goldwasser, Silvio Micali, Ronald L. Rivest , 1995

The scheme possesses the novel property of being robust against an adaptive chosen-message attack: an adversary who receives signatures for messages of his choice (where each message may be chosen in a ..."
