A Survey on Fault Tolerant Data Retrieval in Military Network
نویسنده
چکیده
In military environments, like battlefield or a hostile region, the mobile nodes might suffer from intermittent network connectivity and frequent partitions. Disruption-tolerant network (DTN) technology is the successful solution that allow, wireless devices carried by soldiers to communicate with each other and access the confidential information or command reliably by exploiting external storage nodes. Here, authorization policies are needed in order to retrieve the data securely. Ciphertext-policy attribute-based encryption (CP-ABE) can be provided as the cryptographic solution for the control issues. CP-ABE is applied to the decentralized DTNs. It introduces several security and privacy challenges with regard to the attribute revocation, key escrow, and coordination of attributes issued from different authorities. Here, a scheme where decentralized DTNs use’s CP-ABE with multiple key authorities to manage their attributes with mutual communication is used. Key terms: DTN, Attribute Revocation, Key Escrow, ABE, CP-ABE.

A generalized ABFT technique using a fault tolerant neural network
In this paper we first show that standard BP algorithm cannot yeild to a uniform information distribution over the neural network architecture. A measure of sensitivity is defined to evaluate fault tolerance of neural network and then we show that the sensitivity of a link is closely related to the amount of information passes through it. Based on this assumption, we prove that the distribu...
