By possessing very powerful machines and using parallelization techniques cloud service providers are able to operate on huge amount of data very fast. It follows that TREDISEC security services should maintain this low cloud provider’s latency by making sure that the implemented security services do not add too much complexity to the cloud environment.
Remote Attestation is the activity of making a claim about properties of a target by supplying evidence to an appraiser over a network. The Remote Attestation generates the evidence of whether or not the untrusted cloud platform is running in the expected state, and therefore, the result of the service, application or VM image outsourced to the cloud is trustworthy.
This primitive could be offered as a service to perform biometric authentication on trusted servers while preserving the privacy of the data. It could also be simply adapted to validate ID doc against trusted data sources
It is a cryptographic scheme that enables a cloud provider to compute the multiplication of a given vector with the matrix and to prove to a user that the output is actually correct. The goal of the solution is to render the verification of the proof as efficient as possible.
Cryptographic scheme that enables a cloud provider to evaluate a polynomial over an input received from the user and to prove to a user that the output is actually correct. We consider a scenario whereby a user wishes to outsource a high-degree polynomial P to the cloud server. Further, a queried requests the evaluation of this polynomial over some inputs x. In addition to the output and the server also provides a proof p on the correctness of the output. Finally, the verifier receiving the output and the proof verifies p and concludes whether y equals P(x).
