摘要：Organizations of various types often collects, analyzes and disseminates data rapidly and accurately without exposing sensitive information to unauthorized or entrusted parties[14]. In such applications Anonymous communication is required to provide privacy to the data and nodes which contains this data. Communication anonymity means a particular message cannot be linked to any sender-receiver pair and no message is linkable to a particular sender-receiver pair. Sender anonymity prevents a particular message from being linked to a particular sender identity. Receiver anonymity prevents a particular message from being linked to a particular receiver identity. Several Anonymous Communication Systems have been developed to achieve anonymity including Crowds , Herbivore, Mixminion and Tor. These technologies offer varying degrees of anonymity to protect the user’s identity and provide privacy over a communication systems. The efficiency anonymous protocols depends strongly on a number of factors including: the number of anonymous users, how messages are routed, adversary knowledge and ability and other environmental factors for both the Internet and mobile ad hoc networks. In hierarchical model to provide privacy to the data and data contents we proposed mixnet. Use of Mixnet improves the privacy in the network as well as provides anonymous communication
