Abstract
The present disclosure relates to systems and methods for secure communications. In some aspects, an initiator KMS receives, from an initiator UE, one or more values used in generation of an encryption key, which includes obtaining at least one value associated with a RANDRi. The initiator KMS sends the at least one value associated with the RANDRi to a responder KMS. The responder KMS generates the encryption key using the one or more values.
