Impressions of Intel® SGX performance

Intel® SGX enclaves provide hardware enforced confidentially and integrity guarantees for running computations. This is achieved mainly by encrypting all information as it leaves the CPU, effectively shielding data in the memory from external observers.   But what is the overhead of running computations inside an enclave? One would expect some overheads due to the […]

Test Driving Spark SQL with Intel SGX on Encrypted Data

Protecting sensitive business and personal information is a central requirement when enterprises move to the cloud. Many aspects of this requirement are already handled at various levels. Data-at-rest can be secured in cloud stores by encrypting it before storage, while data-in-flight is transmitted on protected channels such as TLS and HTTPS. Data-in-use, processed in cloud […]

RestAssured Joined the DPSP Cluster

In September 2017 RestAssured became a member of the Data Protection, Security, and Privacy in the Cloud (DPSP) Cluster. Joining the cluster enables RestAssured to maximize the impact of the project’s outcomes by seeking synergies in the methods, tools, and solutions, and identifying future research and innovation needs. The collaboration among the members of the […]

RestAssured Approach Presented at ESOCC 2017

Mike Surridge (IT Innovation) presented the RestAssured approach at an EU Project Workshop attached to the ESOCC 2017 conference in Olso, Norway. The workshop was too short to present more than a high level overview, but it proved useful in raising awareness of what we are trying to do, and also what other projects are […]

Intel SGX Development from IBM

Intel’s SGX technology for creating secure enclaves has the potential to guarantee the security of both data and applications hosted on public clouds.  However, there are numerous limitations on what can be run inside such enclaves and the investment required to learn how to use the SGX SDK for application developers can be quite steep.
