  • Patent number: 7992199
    Abstract: A communications scheme enables a central communications station to assist two communications systems located behind firewalls that prevent communication initiated from an external data network to establish direct communication with each other. In one embodiment, the systems separately establish communications with the central communications station and obtain from it the connection information (e.g., IP address, port, etc.) of the other. The systems then directly communicate with each other using the obtained connection information while pretending to be the central communications station. In another embodiment in which the firewalls include NAT devices that implement network address translation, the systems exchange connection information for establishing a new connection through the central communications station and then complete a three-way handshake with the assistance of the central communications station, thereby allowing the central communications station to remove itself from the communication.

  • Patent number: 7965846
    Abstract: When an SIP interface unit of a server apparatus receives an SIP message for call connection from a client apparatus and an SIP message analyzing unit can confirm that the SIP message is normal, a call controller recognizes that an RTP communication is carried out between the client apparatus and another client apparatus and instructs an encrypting capability management unit to determine RTP encrypting information which is used between the client apparatuses. The encrypting capability management unit determines the RTP encrypting information between these client apparatuses based on the instruction. With this arrangement, there can be provided a client-server distributed system that can realize an encrypting security function without requiring a certificate authentification function at a low cost in order to deliver an encrypting key as well as without necessity of holding or managing a certificate and preparing an authenticating server in a system.

  • Patent number: 7949879
    Abstract: Secure password entry is facilitated by displaying a password prompt comprising a changing stream of random characters, where a particular character within the stream of random characters is displayed at a visibly detectable higher frequency. A user selects a password character by entering input to increment or decrement the particular high frequency character to reach the password character, such that any unauthorized keystroke logging to detect said password is ineffective. Once the user reaches the password character, the user provides another input indicating a selection of the current high frequency character as the password character. Once the user has selected all the characters of the password, the user enters an input indicating the password is complete and the password entry controller then passes the password to the calling layer.

  • Patent number: 7925023
    Abstract: One embodiment of the present invention provides a system for managing keys. During operation, the system authenticates a client at a key manager. Next, the system receives a token from the client at the key manager, wherein the token is associated with a customer key, and includes a token authenticator. This token authenticator comprises one-half of an authenticator pair which is used to determine if the client is the owner of the customer key. Next, the system decrypts the token using a master key. The system then verifies a client authenticator, which comprises the other half of the authenticator pair which is used to determine if the client is the owner of the customer key. If the client is the owner of the customer key, the system sends the customer key to the client, which enables the client to encrypt/decrypt data. Finally, the client deletes the customer key.

  • Patent number: 7904712
    Abstract: A technique is disclosed that allows different computers in a network to create an identifier that uniquely identifies the network. The technique allows the unique identifier to be consistently created over time, regardless of the particular make up of the computing devices in the network at any particular point time. In some implementation, a computer within the network hosts the identification creation tool. In order to create a unique identifier for the network, the tool identifies each network adapter used by the host computer. Using this information, the tool identifies a gateway device used by the network adapter or adapters, and then determines the physical network address of that gateway device. For example, if the network is an Ethernet network, the tool will determine the medial access control (MAC) address for the gateway device. The tool then creates a unique identifier for the network based upon the physical address.

  • Patent number: 7876895
    Abstract: A unified broadcast encryption system divides a media key tree into S subtrees, divides digital content into segments, and converts some of the segments into variations; the number of segments and variations is q. The system subdivides each of the subtrees into q/|S| subdivided subtrees, assigns a key media variant to each of the subdivided subtrees, and generates a unified media key block (MKBu). The system decrypts digital content by obtaining required key media variants from the MKBu, using the key media variant to find an entry in a variant key table, decrypt a title key, and locate a variant number from the variant key table. The system uses the variant number to identify which of the variations may be decrypted by the title key and uses the title key to decrypt segments and variations.
