Abstract: Methods and apparatus are provided for end-to-end security in heterogeneous networks. Hop-by-hop protection techniques ensure that each hop of a signaling path is satisfying one or more predefined security criteria. An end-to-end path is secured at each node by identifying a next hop in the end-to-end path; determining, in response to a received call setup request, if a vendor associated with the next hop in the end-to-end path has satisfied one or more predefined security criteria; and routing the call to the next hop if the vendor has satisfied the one or more predefined criteria. A look-up table can be used to determine whether a vendor has satisfied the one or more predefined security criteria. The look-up table can identify one or more of: (i) vendors that have achieved a predefined security rating; (ii) members in a predefined consortium or business group; and (iii) signatories to a predefined contract or technical specification.

Abstract: A system for managing security keys in a wireless network includes a manufacturer certification authority (MCA) for providing a signed digital MCA certificate for installation into a new network element (NE) at the manufacturer's facility prior to the new NE being installed and initialized in the network. The MCA also provides a source of trusted authority for authenticating legacy NEs in the network. The system includes a service provider certification authority for managing certificates and files used by the NEs to communicate securely within the network, a signing server for providing signing services to NEs for authentication, an element manager for providing security key and digital certificate management, and a management agent (MA) for providing proxy functionality of the EM security key services to NEs not directly connected to the EM.

An authorized capacity corresponds to the peak requirement for the plurality of base stations. The disclosed example includes adjusting an allocation of the authorized total capacity among the plurality of base stations to meet different traffic requirements at each of the base stations at different times.

Abstract: A method and apparatus for defending against a Denial of Service attack wherein a target victim of an attack recognizes the existence of an attack, identifies the source of the attack, and automatically instructs its carrier network to limit (e.g., block) transmission of packets from the identified source to the victim. The victim may identify the existence of an attack based on various criteria determined within the victim's site's infrastructure, and may employ event correlation techniques to make the determination. The victim then communicates one or more source/destination IP (Internet Protocol) address pairs to the carrier, which will then limit the transmission of packets from a specified destination IP address to a corresponding source IP address. The victim may advantageously communicate the source/destination IP address pairs with use of security signatures and by using redundant connections to the carrier network to ensure delivery even under congested network conditions.

Abstract: A method and apparatus for defending against a Denial of Service attack wherein a target victim of an attack has recognized the existence of an attack and identified its source. The carrier network which provides service to the victim automatically receives one or more IP (Internet Protocol) source/destination IP address pairs from the victim, and then limits (e.g., blocks) the transmission of packets from the identified source address to the identified destination address. The carrier may implement this filtering capability as a stand-alone box included in the network, or as a line card incorporated into otherwise conventional network elements already present in the network. The source/destination address pairs to be blocked may be advantageously communicated from the victim with use of security signatures and with use of redundant connections from the victim to the carrier network to ensure receipt even under congested network conditions.

Abstract: Methods and apparatus are provided for authenticating a remote service to another service on behalf of a user. A user client authorizes a remote application client to perform one or more actions on behalf of the user client. The user client provides one or more keys to a remote authentication service; receives an identifier of the remote application client; and notifies the remote authentication service that the remote application client is authorized to obtain a response based on at least one of the one or more keys using the identifier. The remote application client provides a challenge that is received from a server that the remote application client is attempting to access for the user client and an identifier of the user client to a remote authentication service; and receives a response to the challenge from the remote authentication service that is based on one or more keys stored by the remote authentication service on behalf of the user client.

Abstract: A method and apparatus for the early detection of machines infected by e-mail based computer viruses advantageously employs a network behavioral analysis rather than a direct technical analysis of attached executable code. Specifically, an SMTP (Simple Mail Transfer Protocol) log associated with a mail gateway system interconnected to a plurality of machines is examined, and based on an analysis of information comprised in a plurality of log entries thereof, it may be determined that one of these machines has a possible infection by an e-mail based computer virus. Illustratively, information extracted from each entry in the SMTP log (i.e., for each incoming e-mail message) of the mail gateway includes (i) the unique identity of the sending machine; (ii) the “hello” name that the sending machine calls itself, (iii) the e-mail “From:” address; and (iv) whether the message contains a potentially virus-like (e.g., executable) attachment.

Abstract: Secure communication protocols are disclosed in which two parties generate a shared secret which may be used as a secure session key for communication between the parties. The protocols are based on Diffie-Hellman type key exchange in which a Diffie-Hellman value is combined with a function of at least a password using the group operation such that the Diffie-Hellman value may be extracted by the other party using the inverse group operation and knowledge of the password. In one embodiment, each of the parties explicitly authenticates the other party, while in another embodiment, the parties utilize implicit authentication relying on the generation of an appropriate secret session key to provide the implicit authentication. Typically, the parties will be a client computer and a server computer.
