Last time I checked Tor's technical paper (probably been 10 or so years), it stated the fact that a relay? node in between can only decrypt the information required to route to next hop and not the actual packet's payload. Is that correct or am I dreaming?
Also, I recall that if someone malicious flooded the tor network with malicious exit nodes, then all traffic details can be `inferred' right? i.e., the assumption was that exit nodes need to route the packet to destination thus it needed to look at every packet but couldn't infer the originating IP address (based on my dated knowledge :))
If a malicious person now floods the tor network with bazillion exit + relay nodes - then essentially all contents (payload + IP src/dst) can be aggregated. Is this still problem in tor network?
