Elliptic curve cryptosystems in the presence of faults were studied by Biehl, Meyer and M?uller (2000). The first fault model they consider requires that the input point P in the c...
We describe the first domain extender for ideal ciphers, i.e. we show a construction that is indifferentiable from a 2n-bit ideal cipher, given a n-bit ideal cipher. Our construc...
Peer-to-peer content dissemination applications suffer immensely from freeriders, i.e., nodes that do not provide their fair share. The Tit-for-Tat (TfT) incentives have received ...
—The majority of security protocols employ public key cryptography for authentication at least in the connection setup phase. However, verifying digital signatures is an expensiv...
Confidential data hemorrhaging from health-care providers pose financial risks to firms and medical risks to patients. We examine the consequences of data hemorrhages including pri...
