Predicate Encryption Structured Encryption And Controlled Disclosure Cloud Cryptography

Predicate Encryption Structured Encryption And Controlled Disclosure Let’s face it: hundreds of elegant cryptographic schemes have been devised in the last 30 years but only encryption and authentication are deployed in practice. For this purpose, we introduce the notion of structured encryption which generalizes previous work on symmetric searchable encryption (sse) to the setting of arbitrarily structured data. we present a model for structured encryption, a formal security definition and several efficient constructions.

Cloud Cryptography Security Encryption Illustration Ppt Template While the original motivation for structured encryp tion was to perform private queries on encrypted data (or more precisely, private searches on encrypted data), we introduce here a new application which we refer to as controlled disclosure. Confidentiality in cloud storage how do we preserve confidentiality of data in the cloud?. In the context of cloud storage, structured encryption allows a client to encrypt data without losing the ability to query and retrieve it efficiently. We present a model for structured encryption, a formal security definition and several efficient constructions.

Access control cloud provides stronger security than self hosting [molnar schecter 10] q: but what if i don’t trust the cloud operator?. In this talk, we will briefly highlight the opportunities the cloud offers to cryptographers, then we will cover some recent results in the areas of provable data possession and proxy re. To enhance the privacy for receivers, we proposed the first subset predicate encryption schemes with weakly attribute hiding. moreover, our first scheme is constructed over lattices, which is believed to be secure against quantum computers. Our results o structured encryption o formal security definition o simulation based o constructions o adjacency queries on encrypted graphs o neighbor queries on encrypted graphs o focused subgraph queries on encrypted web graphs o controlled disclosure o application to cloud based data brokering.
