Path Problems applied to Computer Security and Cryptography
Labeled paths in directed graphs have many applications. The graph edges are labeled with terminals of context free grammars. This talk presents some new results for labeled paths in digraphs with balanced parenthesis grammars. The focus is on using a basic variation of Nykanan and Ukkonen’s exact path problem to get more efficient shortest paths. Applications to model-based intrusion detection are reviewed. Next the quickest path problem is discussed for labeled digraphs. The quickest path problem accounts for network bandwidth and speed while finding shortest labeled paths. A dynamic programming solution is given for the quickest path problem on labeled digraphs. Applications to cryptographic protocols are outlined.
