Abstract
Systems, methods, and apparatus for facilitating secure over-the-air (OTA) programming are presented herein. A device can store a key, which can be based on a key algorithm (K-algorithm) and an identifier associated with the device. The device can receive information such as parameter(s) and a verification number from a communications system. The verification number can be generated by using an authorization algorithm (A-algorithm) based on the parameter(s) and a K-algorithm input. The device can generate a trial verification number by using the A-algorithm with the parameter(s) and the key as trial inputs. The device can compare the verification number to the trial verification number, and in response to the verification number being at least similar to the trial verification number, the device can use the parameter(s) for programming of the device.
