Mutual Information and Unconditionally Secure Systems
Passive Cryptanalysis of the UnConditionally Secure Authentication Protocol for RFID Systems
... Recently, Alomair et al. embarked on the notion of UnConditionally Secure mu- tual authentication protocol for RFID systems (UCS-RFID)[17]. UCS-RFID’s security relies mainly on the freshness of five ...

Unconditionally Secure Computation with Reduced Interaction
... Very roughly, the intuition we will formalize is as follows: A player whose input matters to the result must somehow communicate his input to the rest of players, in order to enable correct computation of the result by ...
