Abstract
A method in a first node of a wireless communications network comprises: inspecting a data packet or message to determine a characteristic of the data packet or message; and selectively activating integrity protection for onward transmission of the data packet or message to a second node of the wireless communications network based on the determined characteristic.
Claims22
A method in a first node of a wireless communications network, the method comprising:
- inspecting a data packet or message to determine a characteristic of the data packet or message, the characteristic of the data packet or message comprising the following associated with the data packet or message:
- a destination address, a source address, and a size;
- and
- selectively activating integrity protection for onward transmission of the data packet or message to a second node of the wireless communications network based on the determined characteristic, selectively activating integrity protection for onward transmission of the data packet or message comprising:
- activating integrity protection for onward transmission of the data packet or message responsive to a determination of the following:
- the destination is associated with one or more first services,
- the source address is associated with the one or more first services, and
- the size is less than one or more thresholds;
- and
- refraining from activating integrity protection for onward transmission of the data packet or message responsive to a determination of the following:
- the destination address is associated with one or more second services;
- the source address is associated with the one or more second services;
- and
- the size is greater than the one or more thresholds.

A node in a wireless communication network, the node comprising:
- power supply circuitry configured to supply power to the node;
- and
- processing circuitry configured to:
- inspect a data packet or message to determine a characteristic of the data packet or message, the characteristic of the data packet or message comprising the following associated with the data packet or message:
- a destination address, a source address, and a size;
- and
- selectively activate integrity protection for onward transmission of the data packet or message to a second node of the wireless communications network based on the determined characteristic, selectively activating integrity protection for onward transmission of the data packet or message based on:
- activating integrity protection for onward transmission of the data packet or message responsive to a determination of the following:
- the destination is associated with one or more first services, the source address is associated with the one or more first services, and
- the size is less than one or more thresholds;
- and
- refraining from activating integrity protection for onward transmission of the data packet or message responsive to a determination of the following:
- the destination address is associated with one or more second services;
- the source address is associated with the one or more second services;
- and
- the size is greater than the one or more thresholds.
