Asynchrony (due to unknown message transmission delay) complicates the design of protocols for distributed systems. To simplify the protocol design task therefore, the authors propose an interprocess (point-to-point) communication mechanism that has the ...

We pursue to formalize and instantiate a secure bidirectional channel with message franking properties. Under this model a sender may send an abusive message to the receiver and the latter wish to open it in a verifiable way to a third party. ...

We present a process cooperation algorithm for broadcasting m messages among n processes, m ≥ 1, n ≥ 1, in one-port fully-connected communication systems. In this algorithm, the n processes are organized into 2^{⌊log n⌋} one- or two-process units. Messages ...
