Abstract :
A linear scheme is proposed for multiterminal secret key agreement under a private finite linear source model with public discussion. With a wiretapper observing the public discussion and a subset of the source components, it attains the secrecy capacity perfectly and non-asymptotically with a finite block length. Upper bounds on the block length and public discussion rate are given.
