Is there any proper security proposal for non-IP connections ?
Linux box usually can handle TLS properly with mbed-TLS. But non-IP connections also demand a suitable security policy including authentication and verification. Actually BLE is frequently used in smart locks.
But most of the micro can not handle RSA properly. Is there any suggestion ?

Only saw this question now... There is a variety of ways of doing this. X509 certificates are one way of doing it (and support is in mbed TLS). F.e.: a 'lock open' request can be signed by the private key of a certificate, held on f.e. smartphone. The public key is held on the lock, and used to verify if the request came from a trusted party. Make sure to never re-use certificates though.
