Information-Dispersal Games for Security in Cognitive-Radio Networks
Rabin's information dispersal algorithm (IDA) simultaneously addresses secrecy and fault-tolerance by encoding a data file and parsing it into unrecognizable data-packets before transmitting or storing them in a network. In this paper, we redesign Rabin's IDA for cognitive-radio networks where the routing paths are available with uncertainty. In addition, we also assume the presence of an attacker in the network which attempts to simultaneously compromise the confidentiality and data-integrity of the source message. Due to the presence of two rational entities with conflicting motives, we model the problem as a zero-sum game between the source and the attacker and investigate the mixed-strategy Nash Equilibrium by decoupling the game into two linear programs which have a primal-dual relationship.
