Abstract
This invention introduces methods and mechanisms of partial integrity protection in mobile systems. A device comprising: a memory configured to store instructions; and a processor configured to execute the instructions to: generate a representation value based on protocol data unit (PDU) header data and payload data of a PDU; generate a message authentication code based on the representation value; and include the message authentication code in the PDU.
Claims12
A User Equipment (UE) comprising:
- a memory configured to store instructions;
- and
- a processor configured to execute the instructions to:
- generate a Packet Data Convergence Protocol (PDCP) data Protocol Data Unit (PDU);
- and
- perform transmission of the PDCP data PDU to a receiver using a radio interface,
- wherein a format of the PDCP data PDU is arranged in order of a Sequence Number (SN), security information, and data, and
- wherein the security information comprises a plurality of bits and indicates that integrity protection is used or not, and the security information further indicates to derive two or more parameters indicating protection of the data.
A method of a User Equipment (UE), the method comprising:
- generating a Packet Data Convergence Protocol (PDCP) data Protocol Data Unit (PDU);
- and
- performing transmission of the PDCP data PDU to a receiver using a radio interface,
- wherein a format of the PDCP data PDU is arranged in order of a Sequence Number (SN), security information, and data, and
- wherein the security information comprises a plurality of bits and indicates that integrity protection is used or not, and the security information further indicates to derive two or more parameters indicating protection of the data.
A method of a Radio Access Network (RAN) node, the method comprising:
- generating a Packet Data Convergence Protocol (PDCP) data Protocol Data Unit (PDU);
- and
- performing transmission of the PDCP data PDU to a User Equipment (UE),
- wherein a format of the PDCP data PDU is arranged in order of a Sequence Number (SN), security information, and data, and
- wherein the security information comprises a plurality of bits and indicates that integrity protection is used or not, and the security information further indicates to derive two or more parameters indicating protection of the data.
