Abstract
A method and apparatus of key negotiation processing, which includes acquiring, by a control network element, a first key negotiation parameter and a second key negotiation parameter, and sending, by the control network element, the first key negotiation parameter and/or the second key negotiation parameter to the first user equipment UE and a second UE such that the first UE and the second UE generate a key according to the first key negotiation parameter and the second key negotiation parameter. Key negotiation may be performed between two UEs that perform proximity communication.
Claims19
A key negotiation processing method, comprising:
- acquiring, by a control network element, a first key negotiation parameter and a second key negotiation parameter by:
- receiving, by the control network element, a third key negotiation parameter from a first user equipment (UE);
- and
- generating the first key negotiation parameter according to the third key negotiation parameter and a first shared key between the first UE and the control network element,
- acquiring, by the control network element, the first key negotiation parameter and the second key negotiation parameter in response to a proximity communication connection request being sent between the first UE and a second UE, the control network element acquiring the second key negotiation parameter by:
- receiving, by the control network element, a fourth key negotiation parameter from the second UE;
- and
- generating the second key negotiation parameter according to the fourth key negotiation parameter and a second shared key between the second UE and the control network element;
- and
- sending, by the control network element, at least one of the first key negotiation parameter or and the second key negotiation parameter to the first UE and the second UE such that the first UE and the second UE generate a first key according to the first key negotiation parameter and the second key negotiation parameter, and a proximity communication connection is established between the first UE and the second UE using the first key.
