christian janson
I am an Athene Young Investigator in Cryptography and affiliated to the Cryptoplexity team led by Marc Fischlin at Technische Universität Darmstadt in which I have been a Postdoc before as well.
Prior to this I was a Ph.D. student in the Information Security Group at Royal Holloway, University of London under the supervision of Carlos Cid. It all began at Universität Bremen where I studied mathematics and completed my diploma in the AlZAGK group under the supervision of Michael Hortmann.
I am a member of the IACR and my Erdös number is 3.
research interests
My main (current) research interests are:
verifiable outsourced computations
key exchange
secure channels
authenticated encryption
signature schemes
leakage-resilient cryptography
