Patent number: 7512796Abstract: Authentication method for authenticating a mobile node to a packet data network, in which a shared secret for both the mobile node and the packet data network is arranged by using a shared secret of the mobile node and a telecommunications network authentication centre. In the method, the mobile node sends its subscriber identity to the packet data network together with a replay attack protector. The packet data network obtains authentication triplets, forms a session key using them, and sends back to the mobile node challenges and a cryptographic authenticator made by using the session key. The mobile node can then form the rest of the authentication triplets using the challenges and then form the session key. With the session key, the mobile node can check the validity of the cryptographic authenticator. If the authenticator is correct, the mobile node sends a cryptographic response formed using the session key to the packet data network for authenticating itself to the packet data network.Type: GrantFiled: July 25, 2006Date of Patent: March 31, 2009Assignee: Nokia CorporationInventors: Henry Haverinen, Jukka-Pekka Honkanen, Antti Kuikka, Nadarajah Asokan, Patrik Flykt, Juha Ala-Laurila, Jyri Rinnemaa, Timo Takamäki, Raimo Vuonnala, Jan-Erik Ekberg, Tommi Mikkonen, Petri Aalto, Seppo Honkanen

Patent number: 6781954Abstract: Methods and apparatus for signal monitoring of messages in a telecommunications network having a plurality of switches and network elements therein alleviate the need for external hardware to be hooked up to nodes of the network to determine whether faults have occurred at the nodes. A signal monitoring application disclosed herein stores related message signals and messages in a relational database wherein messages and signals having common elements can be easily and quickly viewed. The SIMO application cross-references the messages and signals in the relational database according to a transaction table which categorizes and stores the messages according to parameters set out in the transaction table. This allows the messages to be ranked and viewed very quickly without the need to process them and expend valuable computational time and resources.Type: GrantFiled: January 12, 2000Date of Patent: August 24, 2004Assignee: Nokia Networks OyInventors: Petri Aalto, Timo Takamäki
