We provide a complete investigation of security in the presence of semi-honest adversaries-static and adaptive, with and without erasures-and initiate the study of security in the presence of malicious ...
In contrast, in the sublinear-communication realm erasures have a big effect on the feasibility bound and make the design of an optimal protocol a far more challenging task. ...

We show that using spatial gossip we can compute the erasure codes for the entire network with a total of near linear message transmissions, thus improving substantially the communication cost in previous ...
In a sensor network of n nodes in which k of them have sensed interesting data, we perform in-network erasure coding such that each node stores a linear combination of all the network data with random ...
For this, we keep all the computed coded values in the sensors, instead of replacing them with the newly computed codeword. ...

These codes are a finite-rate generalization of the toric codes, and, for sufficiently large quantum computers, offer an advantage over the toric codes. ...
In particular, we show that any family of LDPC codes, quantum or classical, where distance scales as a positive power of the block length, d ∝ n^α, α>0, can correct all errors with certainty if the error ...
We also give related bounds for fault-tolerant op-eration in the presence of syndrome measurement errors. ...
