Method and system for securely communicating with a machine to machine, M2M, device comprising sharing a secret or data derived from the secret between the M2M device and a server 610/620. Establishing a connection between the M2M device and the server 630. Using the shared secret or data derived from the shared secret to establish cryptographic material on both the M2M device and the server 640 . Securing communication between the M2M device and the server with a cryptographic protocol using the established cryptographic material 650. The cryptographic material is unrecoverable from the shared secret or data derived from the shared secret alone. The shared secret may be generated by the M2M device or the server and communicated to the other of the two. |
