Abstract Denial of service (DoS) attacks are arguably one of the most cumbersome problems in the Internet. This paper presents a distributed information system called Chameleon which is robust to DoS attacks on the nodes as well as the operations of the system. In particular, it allows nodes to efficiently look up and insert data items at any time, despite a powerful ``past-insider adversary'' which has complete knowledge of the system up to some time point t0 and can use that knowledge in order to block a constant fraction of the nodes and inject lookup and insert requests to selected data. This is achieved with a smart replication policy requiring a polylogarithmic overhead only. All requests in Chameleon can be processed in polylogarithmic time and work at every node.
