1. A method for wireless communication, comprising:
selecting a first secure physical uplink channel and a second secure physical uplink channel for multiplexing based at least in part on the first secure physical uplink channel and the second secure physical uplink channel overlapping;
generating a secret key based at least in part on selecting the first secure physical uplink channel and the second secure physical uplink channel for multiplexing in accordance with the first secure physical uplink channel overlapping the second secure physical uplink channel in time;
generating multiplexed information based at least in part on multiplexing the first secure physical uplink channel and the second secure physical uplink channel;
encrypting the multiplexed information based at least in part on the secret key;
indicating to a base station an acknowledgement to use a security degradation function to track a quality of the secret key based on values defined in a security configuration signaled in downlink control information (DCI), radio resource control (RRC), media access control (MAC) control element (MAC-CE), or any combination thereof; and
transmitting the encrypted multiplexed information on a resource associated with the first secure physical uplink channel or a resource associated with the second secure physical uplink channel.
