The method is suitable for the time synchronization system using a precise time protocol. The time synchronization system includes a master node and a slave node, wherein the slave node synchronizes its time with the master node. In the method for encrypting/decrypting packet data of the precise time synchronization protocol, an encryption/decryption hardware device is disposed on the hardware protocol layer of each of the master node and the slave node. The hardware protocol layer is under the data link layer, and includes the data link layer. A synchronization message is encrypted by using the encryption/decryption hardware devices of the master node to generate a frame data, and the frame data is decrypted by using the encryption/decryption hardware devices of the slave node to obtain the synchronization message."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for encrypting/decrypting packet data of precise time synchronization protocol and time synchronization system","description":"A method and an apparatus for encrypting/decrypting packet data of a precise time synchronization protocol and a time synchronization system are illustrated.
