Research interests

Elisabeth's main research interest is in applied cryptography. She focuses thereby on implementation aspects: i.e. what problems arise when (theoretical) cryptography is put into practice by implementing it on different devices which all inevitably leak some form of information. She has spent several years looking into practical methods of dealing with information leakage via the power consumption (and electro-magnetic emanations), and has recently branched out towards dealing with web based side channels.

Besides her work on concrete and practical attacks and countermeasures, she is investigating longer term and more theoretically sound countermeasures tapping into the area of leakage resilient cryptography. Connected to leakage resilient cryptography is her most recent work on smart brute-force key search as well as highly accurate key ranking algorithms.  


Elisabeth lectures on a number of units that deal with Cryptography and Information Security.  She has held the post of Postgraduate Research Director for MVSE until 2016. Currenlty she acts as Senior Tutor for the Computer Science department, where she is also Deputy Head.


Expert in the field of power analysis attacks on cryptographic devices such as smart cards. Generally interested in problems of applied cryptography and information security, some contribution to the analysis of hash functions, and to efficient implementations of cryptographic algorithms.
