摘要：

In this paper, we propose to use Secure Firmware Update over the air of embedded devices, which use TrustZone technology to securely update new firmware. TrustZone will provide authenticity and security of the firmware to be updated in the device. By using trusted application along with host application, it checks integrity, authenticity and security of firmware. We use a digital signature algorithm to verify the authenticity of the firmware with signature verification, which will be carried out securely in TrustZone environment.
