Re: [fw-wiz] covert timing channel data

Here is an example with regards to software algorithms

There is no 'actual interarrival times' or program to generate such an attack - A covert timing channel attack is a method (think of methods of cryptanalysis such as frequency analsysis) to analyze the inner operations of a program based on design differences in operations that make up how the system works. The page I included has an example of a password checking algorithm that could be 'attacked' using a covert timing channel attack because the methodology of the sample program differs based on successful password length.

Subject: [fw-wiz] covert timing channel data


I'm doing research on covert timing channel detection and was not able to get data from any of the authors of various papers describing different covert timing channel techniques. Does anyone know where I can find such data? (either the program to generate it, or the actual interarrival times in a comma separated file)

Thanks and regards,
