Abstract
A method performed by a first IP multimedia system, IMS, node, for handling authentication of a user equipment, UE, in a communication network. The method includes receiving a request from a second IMS node to retrieve an authentication vector. The request includes a private identifier generated from a subscription permanent identifier. The method further includes sending a request to retrieve an indication, where the request includes a subscription permanent identifier, receiving the indication, and generating the authentication vector using the received indication. In addition, the method includes sending the generated authentication vector to the second IMS node for authenticating the UE.
Claims16
A method performed by a User Equipment, UE, for handling authentication of the UE in a communication network, the method comprising:
- generating a password based on any one of a stored first security key and a derived second security key, the password being used for authenticating the UE to a network node, and the first security key being a KAUSF security key;
- and
- sending a message, to a second IMS node for registering the UE to the network node based on the generated password, the message comprising a private identifier and a public identifier.
A User Equipment, UE, for handling authentication of the UE in a communication network, the UE being configured to:
- generate a password based on any one of a stored first security key and a derived second security key, the password being used for authenticating the UE to a network node, and the first security key being a KAUSF security key;
- and
- send a message, to a second IMS node for registering the UE to the network node based on the generated password, the message comprising a private identifier and a public identifier.
