Integrity protection for user plane data in 5g network

Abstract

A method for integrity protection scheme by a mobile communication device or a core network entity according to a first exemplary aspect of the present disclosure includes configuring settings and parameters for integrity protection for user data with another party; receiving user plane data from the other party, calculating Message Authentication Code for Integrity (MAC-I) for a part of the data and checking integrity of the part of the data.

What is claimed is: 
     
         1 . A method for integrity protection scheme by a mobile communication device or a core network entity, the method comprising:
 configuring settings and parameters for integrity protection for user data with another party;   receiving user plane data from the other party;   calculating Message Authentication Code for Integrity (MAC-I) for a part of the user plane data; and   checking integrity of the part of the user plane data, wherein   the mobile communication device only checks integrity of the part of the user plane data and the mobile communication device and the core network entity use shorter MAC-I.   
     
     
         2 . A method according to  claim 1  further comprising:
 reading information on size of the part of the user plane data for integrity protection from the received user plane data. 
 
     
     
         3 . A method for integrity protection scheme by a mobile communication device or a core network entity, the method comprising:
 configuring settings and parameters on integrity protection with the other party;   receiving the data from the other party; and   deciding whether calculating MAC-I for the received data or not.   
     
     
         4 . A method according to  claim 3  further comprising:
 calculating data rate of the received data; and 
 deciding whether calculating MAC-I for the received data or not based on the data rate. 
 
     
     
         5 . A method according to  claim 3  further comprising:
 calculating processing load; and 
 deciding whether calculating MAC-I for the received data or not based on the processing load. 
 
     
     
         6 . A method according to  claim 3  further comprising:
 calculating processing load; and 
 deciding whether calculating MAC-I for the received data or not based on the importance of the received data. 
 
     
     
         7 . A method for integrity protection scheme by a mobile communication device or a core network entity, the method comprising:
 configuring settings and parameters on integrity protection with the other party;   calculating MAC-I for a part of data to be sent; and   sending the data and the MAC-I to the other party.   
     
     
         8 . A method according to  claim 7  further comprising:
 including information on size of the part of the data in the data to be sent.
