Experiments in Encrypted and Searchable Network Audit Logs

We consider the scenario where a consumer can securely outsource their network telemetry data to a Cloud Service Provider and enable a third party to audit such telemetry for any security forensics. Especially we consider the use case of privacy preserving search in network log audits. In this paper we experiment with advances in Identity Based Encryption and Attribute-Based encryption schemes for auditing network logs

Efficient Format Preserving Encrypted Databases

We propose storage efficient SQL-aware encrypted databases that preserve the format of the fields. We give experimental results of storage improvements in CryptDB using FNR encryption scheme

Cryptography Challenges for Computational Privacyin Public Clouds

I was like a boy playing on the sea-shore, and diverting myself now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.- Issac Newton Abstract—Computational privacy is a property of cryptographic system that ensures the privacy of data (and/or operations) while being processed at an untrusted server. Cryptography has been an indispensable tool for computer security but its readiness for this new generational shift of computing platform i.e. Cloud Computing is still questionable. Theoretical constructions like Fully Homomorphic Encryption, Functional encryption, Server aided Multiparty Computation
