Secure Source Coding With a Public Helper [PDF]

IEEE Transactions on Information Theory, 2013
We consider secure multi-terminal source coding problems in the presence of a public helper. Two main scenarios are studied: 1) source coding with a helper where the coded side information from the helper is eavesdropped by an external eavesdropper; 2) triangular source coding with a helper where the helper is considered as a public terminal.

Unfortunately, as Goodhart [7] already remarked: “when a measure becomes a target, it ceases to be a good measure”. And indeed: hiring, grants and tenure decisions depend more and more on performing well in publication metrics.
