AI Technical Summary
Technical Problem
In communication networks, as the complexity of application scenarios increases, the amount of data in the Service Data Unit (SDU) of this layer increases. How to ensure the security of data transmission when the SDU is segmented has become an urgent problem to be solved.
Method used
By assigning a unique target identifier to each PDU segment and providing independent security protection, the security of data transmission is improved by ensuring that each PDU uses different parameters during transmission.
Benefits of technology
While ensuring data transmission security, it reduces the memory pressure on nodes and improves communication efficiency, especially reducing the risk of node crashes in the StarFlash communication system.

Abstract
A communication method and a related device are applied to the technical field of communication. In the application, the SDU is divided into N SDU segments, and the second SDU segment in the N SDU segments is re-segmented to form M SDU segments. A first node can generate a first PDU, the first PDU carries a first SDU segment in M SDU segments, and security protection is performed on the first PDU by using a target identifier corresponding to the first SDU segment. Wherein the target identifier corresponding to the first SDU segment is different from the target identifiers corresponding to the N SDU segments. According to the method and the device, independent security protection can be carried out on the PDU where the SDU segment is located by using the target identifier corresponding to the SDU segment, and for the newly formed SDU segment, the target identifier corresponding to the newly formed SDU segment is designed to be different from the previously generated target identifier, so that the security of data transmission can be improved, and the security performance of the node is improved.
