Data packet processing method and related equipment

The invention discloses a data packet processing method and related equipment, relates to the technical field of information security, and aims to solve the problems that the engineering quantity for modifying application software is relatively large and the practicability is relatively low. The method is applied to target equipment, the target equipment comprises an application processor and a baseband processor, and the method comprises the following steps: the application processor obtains a target data packet; the application processor judges whether the target data packet meets a first preset condition or not; under the condition that the target data packet meets a first preset condition, the application processor encrypts the target data packet to obtain an encrypted data packet; the application processor fills check characters in the encrypted data packet to obtain a check data packet; the application processor sends the verification data packet to a baseband processor; and the baseband processor sends
