Spread Spectrum Storage with Mnemosyne

We motivate and describe Mnemosyne1, a highly private and reliable distributed storage system built over a number of untrusted, unreliable block stores. A client selects the pseudo-random set of block locations used to store a particular file by successive hashing of an initial key value. Resiliency to collisions is obtained by the use of erasure codes. The resulting system operates with decent...

Mnemosyne: Peer-to-Peer Steganographic Storage

We present the design of Mnemosyne1 , a peer-topeer steganographic storage service. Mnemosyne provides a high level of privacy and plausible deniability by using a large amount of shared distributed storage to hide data. Blocks are dispersed by secure hashing, and loss codes used for resiliency. We discuss the design of the system, and the challenges posed by traffic analysis.

Transaction-Based Charging in Mnemosyne: A Peer-to-Peer Steganographic Storage System

Mnemosyne is a peer-to-peer steganographic storage system: one in which the existence of a user’s files cannot be verified without a key. This paper applies the techniques used in Mnemosyne—erasure codes and anonymous block writing—to move most of the administrative overhead of a commercial storage service over to the client, resulting in cost savings for the service provider. The contribution ...
