Disclosed are systems and techniques for wireless communications. For instance, a process can include establishing, by a wireless device (e.g., a user equipment (UE)), access stratum (AS) security between the wireless device and a network node; generating a downlink control information (DCI) encryption key based on a physical layer encryption key generated from an AS key shared with the network node; receiving a DCI transmission from the network node; and decrypting the DCI transmission using the DCI encryption key to obtain scheduling information for the wireless device.
