Security Intelligence for Broadcast : Threat Analytics

Broadcast or multicast is one of the most fundamental concepts in data communication and distributed cryptography. A central entity wishes to broadcast a secret data stream to a dynamically changing privileged subset of recipients in such a way that non-members of the privileged class cannot learn the secret. This work presents an Adaptively Secure Broadcast Algorithm (ASBA) based on threats analytics and case based reasoning. It defines the security intelligence of an adaptively secure broadcast comprehensively with a novel concept. It recommends a set of intelligent model checking moves for the verification of security intelligence of broadcasting mechanism. The algorithm is analyzed from the perspectives of security intelligence, communication complexity, computational intelligence and efficiency of mechanism. The computational intelligence is associated with the complexity of broadcast scheduling, verification of security intelligence of broadcasting system, key management strategies and payment function computation. The cost of communication depends on number of agents and subgroups in the broadcasting group and complexity of data. The algorithm is applicable to the analysis of intelligent mechanisms in static and dynamic networks, auction or combinatorial auction for e-market, digital content distribution through computational advertising, cloud computing, radio and digital TV broadcast, SCADA and sensor networks.
