A wireless device (12) performs authentication (14) with a home network (10H) of the wireless device (12). The wireless device (12) encrypts a network slice identifier (24) with cryptographic key material (22) that is available from the authentication (14) with the home network (10H) and that is shared between the wireless device (12) and the home network (10H). The wireless device (12) transmits a message (20) that includes the encrypted network slice identifier (26). In some embodiments, a network node in a serving network (10S) of the wireless device (12) receives the message (20) and decrypts, or requests decryption of, the encrypted network slice identifier (26) using cryptographic key material (22) that is available to the wireless device (12) from authentication (14) of the wireless device (12) with the home network (10H) and that is shared between the wireless device (12) and the home network (10H). 一种无线设备(12)执行与无线设备(12)的归属网络(10H)进行的认证(14)。无线设备(12)利用加密密钥材料(22)来加密网络切片标识符(24)，该加密密钥材料(22)可从与归属网络(10H)进行的认
