7SHIELD activities presented at the The European Network for Cybersecurity (NeCS) PhD School
February 6 - February 10
7SHIELD was presented at this year’s edition of the European Network for Cybersecurity (NeCS) PhD School. The school was launched six years ago, in response to the increasing need of highly qualified experts in cyber-security. The School addresses the issues of training and development of talented junior researchers, as indicated in the European Cybersecurity strategy and highlighted in the EC’s Digital Agenda. Luigi Romano from CeRICT gave a lecture titled: “Hardware-assisted Trusted Computing: State of The Art and Emerging Use Cases”. In the lecture, he explained that even the most secure algorithm is vulnerable, if the computing environment where it is executed is not adequately protected and he presented the solutions which have been developed in 7SHIELD to provide such protection. In particular, he focused on 7SHIELD protection mechanisms for data “in use” (i.e. it is loaded in the RAM or in the CPU for executing a computation) based on Trusted Execution Environment (TEE) technology. It is worth emphasizing that – while protection of data in transfer and at rest is relatively easy to achieve – protection of data in use is still, to a large extent, an open issue. The challenge here is that data must be also protected from attacks by privileged users (e.g. system administrators or cloud providers) and software (e.g. the operating system or the hypervisor). Protection of data in use is a number one priority in security research, since it the enabling factor of a number of business opportunities. The talk introduced the basic concepts of hardware-assisted security and gave an overview of the current State of The Art of CPU support for Trusted Execution Environment technology. Then, 7SHIELD use cases were presented, where TEE technology was used to effectively improve security in real world setups.
