Abstract
The method includes: receiving, by a first member device, a second EAPOL-MKA packet sent by a second member device; determining, by the first member device, a first cipher suite, and determining a first secure association key SAK corresponding to the first cipher suite; and sending, by the first member device, the first cipher suite and the first SAK to the second member device in CA. Based on the foregoing technical solution, a device in the CA may determine a cipher suite and a secure association key corresponding to the cipher suite that are used for MACsec secure data transmission. In addition, all devices in the CA support the determined cipher suite. In this way, a problem that the cipher suite needs to be re-determined because one or more devices do not support the cipher suite determined by the first device can be avoided.
