Abstract
A constrained device, such as an Internet of Things (IoT) device, can use a handshake procedure to establish a secure transport session with a server and generate a corresponding client session state. The constrained device can encrypt the client session state into an encrypted client session state, and transmit the encrypted client session state to the server. When the constrained device enters an idle mode, the client session state may be cleared from memory of the constrained device. However, when the constrained device next wakes from the idle mode and re-enters an active mode, the constrained device can retrieve the encrypted client session state from the server. The constrained device can decrypt the encrypted client session state to recover the client session state, and use the recovered client session state to resume the secure transport session instead of establishing a new secure transport session with a new client session state.
