Abstract
Methods, systems, and devices for wireless communications are described. Private keys may be maintained upstream in a network at a more secure location. For example, when a signature is needed, a base station may transmit a signing request to a signing function within the core network and may transmit system information (SI) to be protected. The signing function may use a private key to generate a signature for the SI and returns the signature to the base station. The base station may transmit the SI and the signature to user equipment (UEs) within a coverage area of the base station. The UEs may obtain a public key corresponding to the private key and may use the public key to verify that the signature for the SI is valid and from the base station. The public key, and hence the signature, may correspond to a particular tracking area.
