HTTPS is a secure communication protocol based on HTTP and encrypted by using SSL. IoT Platform supports HTTPS. This article describes the HTTPS standard that is supported by IoT Platform.

Supported HTTP versions

  • HTTP/1.0. For more information, see RFC 1945.
  • HTTP/1.1. For more information, see RFC 2616.

Channel security

IoT Platform uses HTTPS to ensure channel security.

Note
  • TLS 1.0, 1.1, and 1.2 are supported. We recommend that you use TLS 1.2 for encryption. TLS 1.0 and 1.1 are previous versions and may pose security risks.
  • Link SDK is configured with TLS 1.2. You do not need to configure the TSL protocol if you use Link SDK.

Limits

  • Only HTTPS is supported.
  • Request parameters cannot be specified after a question mark (?).
  • The resource discovery feature is not supported.
  • After you register a device, you can use only one protocol to connect the device to IoT Platform. You cannot use multiple protocols for the same device.

Usage notes

  • HTTP URIs are consistent with MQTT topics. For more information, see MQTT standard.
  • If IoT Platform identifies that a device submits data over HTTP in the last 10 minutes, the device is in the Online state. This status appears in the IoT Platform console.
