Claim of US Patent No. 10,368,239

1. A method for encrypting a broadcast message of a base station, the method comprising:detecting, by a processor of the base station, a communication impairment at the base station, wherein the communication impairment pertains to a communication between the base station and an endpoint device;
selecting, by the processor of the base station, in response to the detecting the communication impairment, an encryption key for the broadcast message;
encrypting, by the processor of the base station, the broadcast message using the encryption key to create an encrypted broadcast message;
transmitting, by the processor of the base station, an identifier of the encryption key;
transmitting, by the processor of the base station, the encrypted broadcast message over a control channel via a first resource block, wherein the broadcast message includes information identifying that the control channel is to be reassigned from the first resource block to a second resource block; and
reassigning, by the processor of the base station, the control channel of the base station from the first resource block to the second resource block.
