Heartbeat traffic to counter (n-1) attacks

“…RGB Mixes. While none of the flushing algorithms proposed to date have entirely eliminated the threat of the simple but effective (n − 1) attack, Danezis and Sassaman [2003] proposed a technique for detecting when an attacker is conducting the attack, and minimizing its negative impact on the anonymity of legitimate messages. The authors called their approach Red-Green-Black (RGB) mixes.…”

The past two decades have seen a growing interest in methods for anonymous communication on the Internet, both from the academic community and the general public. Several system designs have been proposed in the literature, of which a number have been implemented and are used by diverse groups, such as journalists, human rights workers, the military, and ordinary citizens, to protect their identities on the Internet.In this work, we survey the previous research done to design, develop, and deploy systems for enabling private and anonymous communication on the Internet. We identify and describe the major concepts and technologies in the field, including mixes and mix networks, onion routing, and Dining Cryptographers networks. We will also review powerful traffic analysis attacks that have motivated improvements and variations on many of these anonymity protocols made since their introduction. Finally, we will summarize some of the major open problems in anonymous communication research and discuss possible directions for future work in the field.

“…Though some countermeasures Gülcü and Tsudik, 1996;Möller et al, 2003;Kesdogan et al, 1998;Danezis and Sassaman, 2003) have been proposed to defend (n À 1) attack, none of them can thwart it completely. However, WonGoo can successively protect against (n À 1) attack.…”

AbstractPurpose -As a peer-to-peer scalable anonymous communication system, WonGoo is a tradeoff between anonymity and efficiency. Usually, the longer the path, the stronger the anonymity, but at the same time the heavier the overhead. WonGoo lengthens the anonymity path and reduces the overhead, providing strong anonymity and high efficiency with layered encryption and random forwarding. The purpose of this paper is to analyze its performance in detail. Design/methodology/approach -The paper focuses on measure the performance of WonGoo system with probability theory. First, it gives a brief description of the system and evaluate its payload. Then it presents a detailed security analysis of the system. Findings -It is shown that WonGoo can protect against (n À 1) attack and provide variable anonymity, as well as how confident the collaborators can be that their immediate predecessor is in fact the path initiator. The paper measures the anonymity degree provided by WonGoo system based on information entropy and compare it with other anonymity systems. Practical implications -The paper is helpful for the further development of WonGoo system. In addition, the results presented in this paper will be useful for users to design other anonymity system. Originality/value -WonGoo is a peer-to-peer anonymity system that provides strong anonymity and high efficiency with layered encryption and random forwarding. The paper presents a detailed analysis of its performance with probability theory and measures its anonymity degree with information theory.
