During my VLSI time I was invloved in the development of the SOSCARD CLU chip and the implementation of IAIK’s full custom designed crypto coprocessors for industrial partners. In the Java Security group I am responsible for the IAIK MOA crypto core libraries, the XML signature libraries, the PKI library and the mobile signature solution. I am also involved in IAIK’s Cloud Signature Consortium activities. My main interests are digital signatures and public key infrastructurs.
