Abstract:
The speaker will present in the first part of the talk some ongoing
research. The second part is about a result first presented with
Zbigniew Kotulski and Josef Pieprzykat at ESORICS 2002 in Zurich about
verifiable secret sharing. The approach there works for any underlying
secret sharing scheme. It is based on the concept of verification sets
of participants, related to authorized set of participants. The
participants interact (no third party involved) in order to check
validity of their shares before they are pooled for secret recovery.
Verification efficiency does not depend on the number of faulty
participants.
