Abstract: This disclosure provides an encryption/decryption system, an optical module, and a related apparatus and system, and belongs to the field of network communications technologies. The encryption/decryption system includes an encryption/decryption component, a first interface component, and a second interface component. The encryption/decryption component is configured to encrypt a first physical layer data stream from the first interface component and transmit the encrypted first physical layer data stream to the second interface component, and is configured to decrypt a second physical layer data stream from the second interface component and transmit the decrypted second physical layer data stream to the first interface component. According to this disclosure, a delay caused by encryption/decryption during data transmission can be reduced.

Abstract: A first communication apparatus obtains a first ciphertext data stream, and sends the first ciphertext data stream. The first ciphertext data stream includes a first alignment marker (AM) and an encrypted first data segment. At least one of some bits in a first AM lock information field in the first AM, some bits in a first lane identification information field in the first AM, or some or all bits in a first check information field in the first AM carry encryption parameter information of the first data segment.

Abstract: This application provides a status notification method, an optical module, a network device, and a network system. The method includes: determining a lock status of a logical lane in a first optical module, where the first optical module belongs to a first network device, and the lock status includes a locked state or an unlocked state; and sending uplink notification information when the lock status indicates that the logical lane in the first optical module is locked, where the uplink notification information is used to enable a second optical module to determine that the logical lane in the first optical module is locked, the second optical module belongs to a second network device, and the first optical module is connected to the second optical module.
