Securely exchanging keys to establish secure connections to low powered connected devices (LPCDs), such as smart devices and IoT (Internet Of Things) devices, and mutual authentication between these devices and third party controllers is accomplished via a higher performance machine configured with a dedicated remote service (DRS). A known symmetric pre-shared key (PSK) is used to establish a secure first connection between the LPCD and the DRS using another symmetric key. The DRS can then use asymmetric key exchange to securely send a new symmetric key to the 3P, and send the same new symmetric key to the LPCD using the secure first connection. This facilitates LPCDs to securely establish secure communications with other devices, in particular for control by third party (3P) devices. This also allows authentication of the LPCD with cloud services, and enables a DRS to vouch for associated devices to other DRSs.

Key exchange and mutual authentication in low performance devices

A method for protecting data communications using a multiple processor device in which multiple processors are operatively connected by a transport mechanism for sharing data. One or more of the processors is programmed as a dispatcher and other processors are programmed with processes. Each of the processes enforce an identical security policy and/or perform an identical or specialized security function. Data streams are transferred respectively from the dispatcher to the processes through the transport mechanism. Control information is transmitted through the transport mechanism from one or more processes to the dispatcher. The control information specifies balancing load of the data streams between the processes. The dispatcher balances load based on the control information.
