a system which utilises a computing device to assist an embedded device in providing secure internet communication

摘要

There are disclosed methods, systems and devices whereby SSL or TLS communications between an end-user such as a browsing agent and a small embedded device 4 such as a microcontroller without substantial memory or processing power are made possible. One approach is to provide an interfacing computing device between the end-user 6 and the embedded device 4 comprising an SSL/TLS proxy server/router 1 which translates between a relatively heavyweight encryption protocol used by the end-user 6 and a relatively lightweight encryption protocol used by the embedded device 4. An alternative approach utilises an SSL/TLS assistant computing device that performs computationally expensive encryption/decryption calculations on behalf of the embedded device.
