2 A71CL Overview

The A71CL-ALI is a ready-to-use solution, enabling ease-of-use security for ID2-IoT

device makers to connect to Alibaba Cloud. It is a secure element capable of securely

storing and provisioning credentials and is already pre-provisioned with Alibaba ID2

credentials. It is based on A71 secure element hardware which runs an ID2 application

which manages the ID2 credentials.
The A71CL-ALI solution provides basic security measures protecting the IC against

many physical and logical attacks. It can be integrated with various host platforms and

operating systems to secure a broad range of applications.
