Abstract: This application is applied to the field of communication technologies, and provides a data transmission method, a communication apparatus, and a communication system, to resolve a problem in the conventional technology that user bandwidth is occupied during encrypted transmission. The method includes: generating N ciphertext data streams, where a first ciphertext data stream is any ciphertext data stream in the N ciphertext data streams, the first ciphertext data stream includes at least two first alignment markers AMs and at least two ciphertext data segments, one ciphertext data segment is included between every two first AMs, one first AM is included between every two ciphertext data segments, the at least two first AMs are used for aligning data of the N ciphertext data streams.

Abstract: This application provides a data transmission method, a communication apparatus, and a communication system. The method includes: generating N ciphertext data flows, where a first ciphertext data flow is any one of the N ciphertext data flows, the first ciphertext data flow includes at least two first alignment markers AMs, at least two encryption parameter sets, and at least two ciphertext data segments, one ciphertext data segment and one encryption parameter set are included between every two first AMs, the at least two first AMs are used for data alignment of the N ciphertext data flows; and sending the N ciphertext data flows. The solution may be applied to a physical layer of an optical module or a network device.
