| Summary | 0004841: Mitigate per-user DK set | ||||
| Description | Possible use of the signature of the cumulative hash of all DKs, namely the 'eddsa_sig' field sent along in the /keys response: (2) Different keys per-user is obviously a crucial attack, and this signature allows one to collect _proof_ of the attack. But is this really enough to prevent it? In practice, we probably need to have some real "monitoring" of /keys that can be easily continuously executed by 3rd parties to keep the exchange honest. Future work... | ||||
| Tags | No tags attached. | ||||
| This is some far-off theoretical feature, no need to worry about it for a long time, closing for now. | |
