Firmware is a read-only software that combines hardware, computer architecture, and data. Although the firmware is defined as a state that can only be read, we must also consider the problems of modifying loopholes and adding new features. In particular, hardware that is connected to the Internet should pay more attention to firmware update, and some people will use it. The system is updated at the near end, but it takes a lot of manpower and money. An effective solution is to use remote firmware updates. Although remote updates are efficient, some update processes do not have one-to-many authentication at a time, just like ID-based one-to-one verification, or they cannot hide the update list. In order to overcome these problems, we design a secure verification mechanism that combines the accumulators to achieve over the air (OTA).It is different from previous senders that use OTA to get an updated list. Our sender can protect the user''s privacy by not knowing which meters are updated through the list, and we also ensure the security of the encryption and decryption keys and reduce the calculation time of the verification meter through the accumulator. By using our update process, multiple devices can be verified simultaneously while ensuring basic privacy.
