Abstract:
The present disclosure describes methods and systems, including computer-implemented methods, computer program products, and computer systems, for distributing recovery keys. One method includes: transmitting, from a first user device to a secure community server, a key distribution request, wherein the key distribution request identifies a second user device, and the first user device and the second user device are members of a same secure community managed by the secure community server; transmitting a first portion of a recovery key to secure community server for forwarding to the second user device; transmitting a second portion of the recovery key to the secure community server; and discarding the first portion and the second portion of the recovery key at the first user device.
