The information is as follows:

1. Overview

1.1 Introduction to DTLS encryption

DTLS (Datagram Transport Layer Security) is a datagram transport layer security protocol. It is an extension based on the TLS protocol architecture and is used to ensure the transmission security of UDP connections.

The ONENET platform supports the DTLS protocol based on PSK (pre-shared key) to establish a secure channel between the user device and the OneNET platform for authentication and secure data transmission. The DTLS protocol runs on top of UDP, ensuring the encryption of transmitted data.

1.2 Introduction to ONENET Platform PSK

The device can register to the platform by connecting to the boot machine and directly connecting to the access machine , so it is divided into bs_psk and acc_psk. bs_psk is the psk required for handshake when connecting to the boot machine, and acc_psk is the psk required for handshake when connecting to the access machine. The address for access using the boot machine is 183.230.40.39, the access machine address is 183.230.40.40, and the encryption port is 5864.

What are the guide machine and access machine mentioned in the above information? Please help me explain the difference between the two in their working principles.
