On the Shannon cipher system with a wiretapper guessing subject to distortion and reliability requirements
On the Shannon cipher system with a wiretapper guessing subject to distortion and reliability requirements
We modify the problem studied by Merhav and Arikan (see IEEE Trans. Inform. Theory, vol.45, no.6, p.1860-6, 1999) of discrete memoryless source encrypted messages guessing by wiretapper within given distortion level /spl Delta/ in the case of Shannon cipher system. The security of the system is measured by the expected …
