Applications are invited for a self-funded, 3-year full-time or 6-year part-time PhD project, to commence in October 2019 or February 2020. The PhD will be based in the School of Computing and will be supervised by Dr Mo Adda, Dr Alexander Gegov and Dr Gareth Owenson.

Side Channel attacks are the actions of stealing sensitive data (e.g. secret keys, password and bank details) by exploiting the behaviour of a black box (e.g. a CPU) to infer and steal information from it (e.g. encryption keys). For example, one might steal keys from a smart card allowing them to clone it.

Initially, it was thought side channel attacks are aimed only at stealing secret keys of cryptographic algorithms. Recent research, however, has shown that the side channel attacks can target any kind of data in environments where memory content in kernel space, main memories, databases, smart cards, BTree search algorithms, satellite systems, CAPTCHA, printers, web applications and keystroke are involved.

Meltdown attacks, currently a hotspot area in the modern cloud and native computer systems, are such examples. Attackers use Flush+Reload techniques to exploit the vulnerabilities of victim systems. They can read arbitrary memory locations regardless how isolated they are. The attacks run in users’ unprivileged environment and so do not require any privileges to achieve their objectives. Besides, the exploitation does not leave any traces in the traditional log files. From a digital forensic point of view for instance, it is harder to collect any evidence from the attack. Furthermore, even anti-virus tools are not capable of detecting these attacks, because the anti-virus tools may detect malware by only comparing binary against known signatures.

The aim of this research, based on a previously successful work, is to develop a universal framework to detect the most popular side channel attacks based on Flush+Reload, Prime+Probe, Flush+Flush  +Reload techniques. It relies on a fine-grained program execution attributes when the smallest unit of program is assigned to a processor core’s time line with other workloads, concurrently. This framework utilises program phase proprieties as a security solution in detecting side channel attacks.

This is achieved by taking a course of program phase analysis to extract malicious loops with heterogeneous workloads. The main characteristics of the framework is reliability, efficiency, performance and accuracy, which existing frameworks lack. Machine learning algorithms will be the building blocks of the proposed universal framework to sense, detect and identify malicious attacks on the cloud computer system.
