—Detection engines capable of inspecting packet payloads for application-layer network information are urgently required. The most important technology for fast payload inspection is an efficient multipattern matching algorithm, which performs exact string matching between packets and a large set of predefined patterns. This paper proposes a novel Enhanced(More)
BACKGROUND DNA signatures are distinct short nucleotide sequences that provide valuable information that is used for various purposes, such as the design of Polymerase Chain Reaction primers and microarray experiments. Biologists usually use a discovery algorithm to find unique signatures from DNA databases, and then apply the signatures to microarray(More)
—Intrusion Detection Systems (IDSs) are known as useful tools for identifying malicious attempts over the network. The most essential part to an IDS is the searching engine that inspects every packet through the network. To strictly defend the protectorate, an IDS must be able to inspect packets at line rate and also provide guaranteed performance even(More)
The homology search within genomic databases is a fundamental and crucial work in biological knowledge discovery. With exponentially increasing size and access of databases, the issues of efficient retrieval become more essential in bioinformatics. Due to the varieties of biological data, similar sequences are not only under some error tolerance, but are(More)
Expressed Sequence Tags (EST) are widely used for the discovery of new genes, particularly those involved in human disease processes. A subsequence in an EST dataset is unique if it appears only in one EST sequence of the dataset but does not appear in any other EST sequence. The unique subsequences can be regarded as signatures that distinguish an EST from(More)
The homology search within genomic databases is a fundamental and crucial work for biological knowledge discovery. With exponentially increasing sizes and accesses of databases, the filtration approach, which filters impossible homology candidates to reduce the time for homol-ogy verification, becomes more important in bioinformat-ics. Most of known(More)
Signatures are short sequences that are unique and not similar to any other sequence in a database that can be used as the basis to identify different species. Even though several signature discovery algorithms have been proposed in the past, these algorithms require the entirety of databases to be loaded in the memory, thus restricting the amount of data(More)
