Unforgeability - Open Access .click

2021
In this paper, we give the first formal security analysis on the one-more unforgeability of blind ECDSA. We start with giving a general attack on blind ECDSA, which is similar to the ROS attack on the blind Schnorr signature. We formulate the ECDSA-ROS problem to capture this attack.

Strong unforgeability in group signature schemes

Computer Standards & Interfaces, 2009
A signature scheme is strongly unforgeable if no adversary can produce a new valid signature @s on a message M even after seeing some signatures on M. We define strong unforgeability of group signature schemes and explain why the strong unforgeability of a group signature scheme is necessary. This relatively new security concept was not considered when

BETWEEN FORGIVENESS AND UNFORGIVENESS

The Heythrop Journal, 2010
Although demanding and hard to grant, forgiveness has been treasured for centuries because it has the power to heal emotional wounds, restore human relationships and break the chain of violence. Some writers, though, have asserted that forgiveness found its boundaries in Auschwitz; the Nazi crimes against humanity reached the pinnacle there and cannot ...
