Anonymous networking amidst active adversaries
2009
MILCOM 2009 - 2009 IEEE Military Communications Conference
Preserved Fulltext
Using numerical examples, the tradeoff between the achievable anonymity and the power of the adversary is demonstrated as a function of the throughput for passive and active adversaries. ...
The problem of anonymous wireless networking is considered when adversaries who monitor the transmissions in the network are also capable of compromising a fraction of nodes to extract network information ...
In that setup, the uncertainty in the choice of nodes to monitor gives rise to a game-theoretic formulation. ...

At the saddle point, the strategy of the network designer is to ensure that any subset of nodes monitored by the adversary reveals identical amount of information about the routes. ...
Quantifying anonymity using conditional entropy of the routes given the adversary's observation, the problem of optimizing anonymity is posed as a two player zero-sum game between the network designer ...
The adversary's goal is to identify which of these sessions is currently active in the network by monitoring the transmission timing of the monitored nodes. s 1 = {(A 1 , B 1 , C 1 ), (A 2 , B 2 , C 2 ...

Similarly, the Scanner faces a dilemma: the wider the bandwidth scanned, the higher the probability of detecting the Invader, but at the expense of increasing the cost of building the scanning system. ...
In particular, we have found a discontinuous dependence of the equilibrium strategies on the network parameters, fine and the type of the Invader's award. ...
The game has a saddle point in mixed strategies, and let P (x, y) be the value of the game. Then P (x, y) is the maximal detection probability of the Invader under worst conditions.

A defense mechanism can increase the adversary's uncertainty by introducing controlled errors in the victim model's decisions (i.e., poisoning the adversary's training data). ...
The interactions between the defender and the adversary are formulated as a non-cooperative game, where the defender selects the probability of defending or the defense level itself (i.e., the ratio of ...

In this paper, we consider the path bias attack– where the attacker induces a client to use compromised nodes and thus links the client to their destination. ...
We show provable bounds for the sample complexity of the scheme and describe methods to make it resilient to introduction of false data by the attacker to subvert the detection process. ...
