According to another aspect of the subject matter described herein, includes receiving or generating a service based interface (SBI) request message. The method further includes identifying a next-hop network function (NF) of the SBI request message. The method further includes determining, from a registered profile of the next-hop NF, whether the next-hop NF supports handling of encrypted SBI request message parameters. The method further includes in response to determining that the next-hop NF supports handling of encrypted SBI request message parameters: encrypting selected SBI request message parameters; adding one or more headers to the SBI request message or updating one or more headers in the SBI request message to facilitate identification and decryption of the encrypted SBI request message parameters; and transmitting the SBI request message to the next-hop NF.
