Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] See figure 1 , which is a structural block diagram of an embodiment of the mobile terminal of the present invention.

[0040] like figure 1 As shown, the mobile terminal includes AP1 and Modem2, and there is two-way communication between them. That is, AP1 can send data to Modem2, and Modem2 can also send data to AP1. When AP1 sends data to Modem2, AP1 is the data sender and Modem2 is the data receiver. When Modem2 sends data to AP1, Modem2 is the data sender and AP1 is the data receiver. In order to verify the data received by the data receiver, in this embodiment, the mobile terminal further includes a first data verification device 11 and a second data verification device 21 . Specifically, a first data verification device 11 is prov...

Abstract

The invention discloses a data verification method, a verification device and a mobile terminal. The data verification method comprises the steps that a receiver receives data and executes the following verification process of obtaining an ID of receiving data and looking for a data structure corresponding to the ID of the receiving data from a stored data structure; after the corresponding data structure is found, the receiving data type is obtained and compared with a stored legal data type, and the legality of the receiving data type is judged; when the receiving data type is legal, a valve of the receiving data with a limited value domain is obtained according to the data type and compared with a legal value of the stored data belonging to the type, and the legality of the value of the receiving data is judged; if the found corresponding data structure, the receiving data type and the value are legal, the receiving data is confirmed as legal data; if the found corresponding data structure, the receiving data type and the value are illegal, the receiving data is illegal data. By applying the data verification method, the verification device and the mobile terminal, the problem that verification on the legality of the receiving data cannot be performed in the prior art can be solved.

Description

technical field [0001] The invention relates to data processing technology, in particular to a data verification method, a verification device and a mobile terminal. Background technique [0002] The hardware structure of an existing intelligent mobile terminal (such as a smart phone) includes two parts, an AP and a Modem. AP is an application program processor, which is a hardware function module that runs an application operating system; Modem is a modem, a hardware function module that runs voice and data communications, and is responsible for the execution of all communication software. AP and Modem are separated in hardware, and the two usually communicate through AT commands. [0003] Currently on the market for smart mobile terminals, when AP and Modem exchange data through AT commands, after receiving the data, the receiver usually only checks the received data for transmission correctness such as CRC check, and checks the received data. Whether it is the same as t...
