Abstract
A user device is configured for communication with a distributed verification system over a network. The user device generates first and second keys from a master key for a password vault or other credential store, provides the first key to the distributed verification system, encrypts the credential store based at least in part on the second key, and provides the encrypted credential store to the distributed verification system. The credential store is encrypted utilizing the second key and information that is stored in a distributed manner over a plurality of servers of the distributed verification system. For example, encrypting the credential store illustratively comprises generating a ciphertext by encrypting the credential store utilizing the second key, obtaining a third key stored in the distributed manner over the servers, and encrypting the ciphertext utilizing the third key to generate the encrypted credential store that is provided to the distributed verification system.
