Embodiment Construction

[0019] Such as figure 2 As shown, the mobile communication terminal architecture of the secure encryption communication of the present invention includes an application processor 1 and a baseband processor 2, and also includes a security chip 3, one end of the security chip 3 is connected to the application processor 1, and the other end is connected to the baseband Processor 2 is connected.

[0020] Preferably, the application processor 1 and the baseband processor 2 are packaged as one by using the system-in-package technology, and are respectively connected to the security chip 3 outside the package by signals.

[0021] System-in-Package (SiP) technology is one of the important ways to achieve high-density and high-integration chips. Among them, the Chiplet (literally translated as "small chip") based on SiP technology manufactures chips by building blocks. It is a type of die that meets specific functions. Multiple dies are connected to each other through die-to-die inte...

Abstract

The invention discloses a mobile communication terminal architecture for secure encrypted communication. An encryption algorithm is convenient to upgrade and good in confidentiality. The mobile communication terminal architecture for security encryption communication comprises an application processor (1) and a baseband processor (2), and further comprises a security and secrecy chip (3), one endof the security and secrecy chip (3) is connected with the application processor (1), and the other end of the security and secrecy chip is connected with the baseband processor (2). Preferably, the application processor (1) and the baseband processor (2) are packaged into a whole by adopting a system-in-package technology, and are respectively in signal connection with the security chip (3) arranged outside the package. Therefore, physical separation of the baseband processor data and the application processor data is ensured, and safe and reliable communication is provided for the two processors.

Description

technical field [0001] The invention belongs to the technical field of mobile communication equipment, in particular to a mobile communication terminal architecture for secure encrypted communication. Background technique [0002] A mobile communication terminal (communication digital processing chip) is usually composed of an application processor (AP), a baseband processor (CP), a hardware accelerator, a radio frequency processing chip, and other peripheral interfaces. As baseband chips support more and more wireless communication modes, the complexity of the chip structure increases, and the speed of data exchange with application data continues to increase. At the same time, communication security issues are becoming more and more important. [0003] Among them, the application processor (AP) chip mainly completes the functions of platform application software operation, channel control, human-computer interaction processing, simple signal preprocessing and communication...
