Abstract: Systems and methods for secure peer-to-peer communication are disclosed herein. Various embodiments of the present invention advantageously enable authentication of a remote device, but without the use of a PKI certificate, and more generally, without requiring involvement from outside parties. In an exemplary embodiment, a password-protected message may be sent to a remote device, the password-protected message containing a unique identifier of a local device and a locally generated random number. Upon accessing the password-protected message, the remote device may reply to the local device including its own unique identifier and a remotely generated random number, where the reply is encrypted using the locally generated random number. An acknowledgement message may then be sent to the remote device including a mutually unique key, where the acknowledgement message is encrypted using the remotely generated random number.
