Summary0003313: DHT GET randomization should increase with time
DescriptionSuccesive GET requests should increase the amount of randomization with succesive requests, in order to try to defeat Sybil attacks capable of eclipsing ALL randomized key from a smaller pool.
Additional InformationIf an attacker is able to eclipse 512 keys, randomizing over 8 bits would not work as all 256 keys are eclipsed. The GETs should start trying with 9 bits (which would also keep failing) and then 10 bits (with 1024 possible targets), which would eventually succeed.
