ANONYMOUS AND UNLINKABLE DISTRIBUTED COMMUNICATION AND DATA SHARING SYSTEM

摘要

A distributed communication and data sharing system that provides anonymity and unlinkability. A group comprising a number of structures, each having a public/private key pair, is stored on a plurality of nodes in a Distributed Hash Table. Advantageous features of the group management system are provided through the use of Cryptographically Generated Addresses (CGA) for the structures, a secure capture method that enables a user to capture an address and be the only one authorized to request certain operations for the address, and an anonymous get/set mechanism in which a user signs messages, encloses the public key in the message and encrypts the message and public key using the public key of the receiver. The distributed communication and data sharing system of the invention can advantageously be used for group management of social networks.
