Jorden Whitefield

Computer Security Researcher


Jun. 2019 - Oy L M Ericsson Ab, FI Specialist Security Technology.

Jan.-Jun. 2019 Aalto University, FI Visiting Post Doctoral Researcher.

2013 - 2014 Accenture, UK Associate Software Engineer.

I developed hybrid mobile applications for Android and Apple iOS. I extended legacy UK government software systems with a RESTful API layer to integrate with modern systems.


2015 - 2019 University of Surrey Computer Security PhD (Funded EPSRC iCASE with Thales UK)

PhD supervisors: Liqun Chen, Steve Schneider, and Helen Treharne.

My thesis was titled: Formal Analysis and Applications of Direct Anonymous Attestation.
Thesis - Surrey ePubs

2016 - 2017 University of Surrey Graduate Certificate in Learning and Teaching.

I am a fellow of the Higher Education Academy UK (Reference #: R137274). The course explored the theory and practice of teaching, curriculum design and implementation, and pedagogy research.

2011 - 2015 University of Surrey BSc Computer Science (First class honours)

Dissertation Project: Linking ProB and LTSmin.

I was awarded the EDF Best Digital Project Prize for achieving the highest mark for the dissertation project.

I received a scholarship from the University of Surrey for performance in my studies.

Modules I studied include: Computer Security, Information Security Management, Software Engineering Project.


2017 Thales eSecurity UK (Cambridge, UK)

Thales indicated a strong interest in Trusted Platform Modules (TPM) and Trusted Execution Environments (TEE) and how these technologies can be used within security protocols, e.g., investigating how Direct Anonymous Attestation could be applied in the vehicular domain.

I also defined a scope of work in collaboration with Thales aligned to their trusted computing agenda. I developed a demonstrator of the O-Token protocol defined in my STM 2017 paper. I was responsible for leading the project, defined an initial software requirements specification, supervised a graduate student in the development of the demonstrator and presented outcomes for internal review.


EPSRC UK Impact Acceleration Account, Privacy-enhanced capabilities for VANETs using Direct Anonymous Attestation (£47k)

Co-Investigator: January 2018 - December 2018

Project partners: University of Surrey, Pervasive Intelligence UK, Thales Research and Technology UK

Defined the architecture to be used within the proposal to build a demonstrator for privacy-preserving Vehicle-2-Anything (V2X) communications by employing Direct Anonymous Attestation that is standardized in ISO/IEC 20008-2 & 11889.

Co-wrote the work packages within the proposal.

The demonstrator is implemented in a relevant lab environment using NexCom automotive boxes, TPM development kits, various communication interfaces and message standards.

CS-E4310: Mobile Systems Security, Aalto University

I graded student exercises, and I was responsible for organising the student presentation portion of the course.

CS-E4000: Seminar in Computer Science, Aalto University

I supervised two MSc students to produce special assignment reports. One of the students reviewed the state-of-the-art and limitations of Android app collusion attacks. The other student reviewed the attack surface of man-in-the-middle attacks on Android.


COM3009: Computer Security, University of Surrey

I was a lab demonstrator for lab sessions for a class of 40 final year students.

I supported student learning in cryptography, application of CrypTool for lab exercises and symbolic security protocol verification in Scyther.

COM2039: Parallel Computing, University of Surrey

I was a lab demonstrator for lab sessions for a class of 60 second year students.

Supported student learning in labs for basics of programming NVIDIA CUDA in C.

2016 COM1032: Mobile Computing, University of Surrey

I provided support in lab sessions on Android, Java and Android Studio.

I was the marking lead for two assignments for over 100 students, which required evaluation of Java code and testing on tablets. Experienced in using grade descriptors and automated feedback and personalised formative feedback.

2015 COM1028: Programming Fundamentals, University of Surrey

I was the lead lab demonstrator for practical sessions in the lab sessions for class of 60 first year students.

I mentored students to become lab demonstrators for this module.

I lead tutorial sessions for students who required extra support in groups of 20 or more.

The module aim was to deliver fundamentals of programming using Java in Eclipse IDE.
