Abstract

Example embodiments of the present disclosure relate to methods, apparatus, devices, and media for passive optical network activation. According to an example embodiment of the present disclosure, a first device receives a key control message from a second device during a key exchange. The key control message instructs the first device to generate a key by employing an encryption algorithm to be used and transmit the key, or to confirm the key corresponding to the encryption algorithm currently used. The key control message also instructs the first device to generate a key report based on the key control message and to send the key report to the second device. In this way, the key and the encryption algorithm in the communication process of the first device and the second device can be matched, and the stability of the channel operation is improved.
