Abstract

The invention discloses a security chip COS firmware updating method, which comprises the following steps of receiving a security chip COS firmware updating request sent by a terminal; verifying the identity of the terminal; after the identity of the terminal is verified, using a first random key for performing symmetrical encryption on the new version COS firmware and an HASH value of the COS firmware; performing asymmetrical encryption on the first random key; sending the encrypted data to the terminal so that the terminal performs decryption on the received data; after the HASH value pass the checking, updating the new version COS firmware. The asymmetrical and symmetrical combined encryption technology is used; the random key is used for transmitting data in an encrypted way; the security of the updating data in the transmission process is protected; the security chip COS firmware updating can be securely, reliably and conveniently realized. In addition, the invention also provides a security chip COS firmware updating server side, the terminal and a system. The technical advantages are also realized.

Description

technical field [0001] The invention relates to the technical field of cryptographic operation chips of semiconductor technology, in particular to a security chip COS firmware update method, server, terminal and system. Background technique [0002] With the continuous innovation of smart devices, people begin to rely on smart devices in many aspects of daily life, and there are more and more personal privacy leakage problems caused by smart devices, and people pay more and more attention to information security.
