Abstract
A first electronic device can establish a communication channel with a second electronic device and receive a second signed log head of an identifier log via the communication channel. The identifier log is managed by a key transparency server and can include public keys of users registered with the server and user identifiers. The second signed log head includes a hash of the public keys and the user identifiers in the identifier log. The second signed log head can be provided to the second device by the server. In response to sending a request for a consistency-checked log head from the server, the device can receive at least one consistency-checked signed log head. The device can verify a consistency between the second signed log head and the at least one consistency-checked log head. If verified the device can maintain use of the server for verifying ownership of the keys.
