Perfectly Secure Message Transmission Scheme against Rational Adversaries
secure message transmission game theory rational adversary
2017/4/12
Secure Message Transmission (SMT) is a two-party cryptographic scheme by which a sender securely and reliably sends messages to a receiver using nn channels. Suppose that an adversary corrupts at most...
On the Communication Complexity of Reliable and Secure Message Transmission in Asynchronous Networks

Reliable and Secure Message Transmission Protocols
2010/7/13
Consider the following problem: a sender S and a receiver R are part of an unreliable, connected, distributed network. The distrust in the network is modelled by an entity called adversary, who has un...
Cryptanalysis of Secure Message Transmission Protocols with Feedback (Full version of the ICITS 2009 paper with the same title and authors)

2009/12/29
In the context of secure point-to-point message transmission in networks with minimal
connectivity, previous studies showed that feedbacks from the receiver to the sender can be used to
reduce the r...
