  • Patent number: 9693226
    Abstract: Method and Apparatus for Securing a Connection in a Communications Network A method of operating a user equipment (UE) using a Generic Bootstrapping Architecture (GBA) is provided. The method includes establishing a shared secret between the UE and a Network Application Function (NAF). An authentication request is sent to a Bootstrapping Server Function (BSF) by the UE. An original parameter intended for a key derivation function and a bootstrapping transaction identifier is received from the BSF. An application request, including the bootstrapping transaction identifier, is sent by the UE to the NAF. A modified parameter is derived by the UE from the secret and the original parameter intended for the key derivation function. A cryptographic key is determined using said modified parameter in place of or in addition to the original parameter in the key derivation function, and communications with the NAF are secured using the key.

  • Patent number: 9622028
    Abstract: This disclosure relates to methods and arrangements for positioning of a communication device (102, 202, 208, 402, 502) in a communication system. Based on received radio channel information from a positioning server (112, 212, 408, 508), positioning nodes (104a-d, 204, 206, 410, 412, 510) identify (S-430, S-538, 704) a radio signal from said communication device, measure (S-432, S-433, S-540, 706) the strength of said received signal and sends (S-434, S-435, S-542, 708) signal strength information and position information of the positioning nodes to said positioning server. The positioning server then determines (S-436, S-544, 610) the position of the communication devices based on the received signal strength measurements and the position information of the positioning nodes. High accuracy in-door positioning of communication devices is achieved.

  • Publication number: 20150281958
    Abstract: A method of securing a session between a Network Application Function, NAF, and a User Equipment, UE, connected to a network. The NAF is assigned a NAF identifier, NAF_id, using the Generic Bootstrapping Architecture, GBA, or a similar architecture and a shared secret is established between the UE and the NAF (S7.1). An application request containing a bootstrapping transaction identifier is sent to the NAF from the UE (S7.2) and an authentication request comprising the bootstrapping transaction identifier, the NAF_id, and information derived from the shared secret is sent to a Bootstrapping Server Function, BSF, from the NAF (S7.4). The BSF and the UE determine a NAF key, Ks_NAF, by using a modified parameter in place of or in addition to an original parameter in a key derivation function, the modified parameter being derived from the shared secret and the original parameter of the key derivation function (S7.5). This NAF key is transmitted from the BSF to the NAF (S7.
