Claim 15:
16. A computer-implemented method comprising:
receiving, by a first access point, from a key management service, a cryptographic key associated with a client device, wherein the key management service operates to:
learn migration behavior associated with the client device;
receive a notification that comprises a second access point and a neighborhood list, wherein the second access point is the access point the client device is currently connected to and the neighborhood list is a list of access points in the neighborhood of the second access point;
predict a subset of neighbor access points from the neighborhood list based on the second access point and the learned client device migration behavior, wherein the size of the subset is dynamically adjusted using machine learning and the first access point is included in the subset;
generate cryptographic keys associated with the client device for each of the subset of neighbor access points; and
propagating one of the cryptographic keys associated with the client device to each of subset of neighbor access points; and

caching, by the first access point, the cryptographic key associated with the client device.
