On The Use Of Negative Selection In An Artificial Immune System
نویسندگان
چکیده
The natural immune system is very e ective at protecting the body from diseases. Several researchers have analyzed the natural system and created arti cial systems which copy mechanisms of the natural system in order to improve computer security. We suggest that the negative selection algorithm, which is at work in the natural system, might have been copied too closely. We argue against the use of negative selection if space is nite and self comprises only a small fraction of the available space or if space is in nite. We illustrate this on the problem of user authentication using keystroke analysis.

In this paper we have designed a new algorithm based on nega...
متن کاملBeeID: intrusion detection in AODV-based MANETs using artificial Bee colony and negative selection algorithms
Mobile ad hoc networks (MANETs) are multi-hop wireless networks of mobile nodes constructed dynamically without the use of any fixed network infrastructure. Due to inherent characteristics of these networks, malicious nodes can easily disrupt the routing process. A traditional approach to detect such malicious network activities is to build a profile of the normal network traffic, and then iden...
متن کاملNegative Selection Based Data Classification with Flexible Boundaries
One of the most important artificial immune algorithms is negative selection algorithm, which is an anomaly detection and pattern recognition technique; however, recent research has shown the successful application of this algorithm in data classification. Most of the negative selection methods consider deterministic boundaries to distinguish between self and non-self-spaces. In this paper, two...
