Abstract
During a security technique, an electronic device determines a name by a applying a function to a shared secret, which is shared between a user and another user. This name is advertised in a network. After discovery by another electronic device (which is associated with the other user), the electronic device generates a first encrypted message from an unencrypted message using a cryptographic key. The electronic device provides the first encrypted message to the other electronic device, and receives a second encrypted message from the other electronic device. Using the cryptographic key, the electronic device decrypts the second encrypted message. Moreover, the electronic device receives confirmation that the other electronic device was able to decrypt the first encrypted message, thereby authenticating that the secure connection has been established.
