Abstract :
We present a P2P filesharing system that allows redundant storage of shared files in a way that no participating server ever stores data that could compromise its operator. Instead, only fragments that do not contain any information about the original file in the information theoretic sense are uploaded. Reconstruction of a file requires all fragments it has been decomposed into. By this, in conjunction with other cryptographic methods, we yield significant legal advantages for server operators, as well as censorship-resistance, anonymity, secure routing, authenticated file update and integrity checks.
