A network device comprises a storage device storing an application program for a secure communications service, and at least one processor configured to execute the application program for the secure communications service so as to enable the network device to send a request to look up a network address of a second device based on an identifier associated with the second device, receive an indication that the second device is available for the secure communications service, the indication including the requested network address and provisioning information for a secure communication link, connect to the second device over the secure communication link, using the received network address of the second device and the provisioning information for the secure communication link, and communicate at least one of video data and audio data with the second device using the secure communications service via the secure communication link.

Agile network protocol for secure communications using secure domain names

A method performed by a first network device for communicating over a network, the method includes receiving, at the first network device, a request to connect to a second network device. The method includes, based on the request to connect, determining whether the first network device is set to an encrypted communication mode. The method further includes, based on a determination that the first network device is set to the encrypted communication mode, sending, to a first name service, a first name associated with the second network device and for which the first name service supports establishing an encrypted connection to the second network device. The method further includes receiving, at the first network device, a resource for the encrypted connection to the second network device, wherein the resource indicates a quality of service level for the encrypted connection determined by the first name service, and communicating with the second network device over the network via the encrypted connection using the received resource indicating the determined service level for the encrypted connection.

Method for establishing connection between devices

A secure domain name service for a computer network is disclosed that includes a portal connected to a computer network, such as the Internet, and a domain name database connected to the computer network through the portal. The portal authenticates a query for a secure computer network address, and the domain name database stores secure computer network addresses for the computer network. Each secure computer network address is based on a non-standard top-level domain name, such as .scom, .sorg, .snet, .snet, .sedu, .smil and .sint.

A system and method for video conferencing over a secure communication link is disclosed. In various implementations, the system is configured connect to a communication network, store a plurality of network addresses of devices of registered users, each device of a registered user having an application program for conducting video conferencing between, the client device and the target device, and establish a secure communication link between the client device and the target device. The secure communication link is established in response to a query (a) generated by the client device and (b) including an identifier associated with a network address of the target device, the establishment of the secure communication link being based on a determination that the target device can accept a secure communication link connection with the client device. Video conferencing is conducted over the secure communication link connection between the client device and the target device.

Agile network protocol for secure video communications with assured system availability

A system for connecting a first network device and a second network device includes one or more servers. The servers are configured to: (a) receive, from the first network device, a request to look up a network address of the second network device based on an identifier associated with the second network device; (b) determine, in response to the request, whether the second network device is available for a secure communications service; and (c) initiate a virtual private network communication link between the first network device and the second network device based on a determination that the second network device is available for the secure communications service, wherein the secure communications service uses the virtual private network communication link.

System and method employing an agile network protocol for secure communications using secure domain names

A plurality of computer nodes communicates using seemingly random IP source and destination addresses and (optionally) a seemingly random discriminator field. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are rejected. In addition to 'hopping' of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped. The hopped addresses are generated by random number generators having non-repeating sequence lengths that are easily determined a-priori, which can quickly jump ahead in sequence by an arbitrary number of random steps and which have the property that future random numbers are difficult to guess without knowing the random number generator's parameters. Synchronization techniques can be used to re-establish synchronization between sending and receiving nodes.

Agile network protocol for secure communications with assured system availability

A device and method for establishing a connection between devices is disclosed. A first device receives a request to connect to a second network device and, based on the request, a determination is made as to whether the first device is set to a first communication mode or a second communication mode. If the first device is set to the first communication mode then a first name associated with the second device is sent to a first name service, the first name service supporting establishing an encrypted connection to the second device, a resource for the encrypted connection to the second device is received at the first device, and communication with the second device is established over the network via the encrypted connection using the received resource. If the first device is set to the second communication mode then communication with the second device is established via a second connection.

A system for and method of establishing a secure communication link is disclosed. The method comprises: (1) generating a Domain Name Service (DNS) request; (2) determining that the DNS request corresponds a first computer configured to communicate securely; (3) sending, based on the determination, a request to establish a secure communication link with the first computer configured to communicate securely, the request including an identifier of a client device used to determine whether the client device is authorized to communicate with the first computer; (4) receiving, in response to the request to establish a secure communication link, a resource used to establish the secure communication link; (5) automatically establishing the secure communication link using the received resource; and (6) communicating securely with the first computer over the established secure communication link.

System and method for establishing a communication link

A technique is disclosed for establishing a secure communication link between a first computer and a second computer over a computer network. Initially, a secure communication mode of communication is enabled at a first computer without a user entering any cryptographic information for establishing the secure communication mode of communication. Then, a secure communication link is established between the first computer and a second computer over a computer network based on the enabled secure communication mode of communication. The secure communication link is a virtual private network communication link over the computer network in which one or more data values that vary according to a pseudo-random sequence are inserted into each data packet.

Method for establishing secure communication link between computers of virtual private network

A client device comprises: (a) a memory, (b) an application program, and (c) a signal processing configuration. The memory is configured and arranged to facilitate a connection of the client device with a target device over a secure communication link created based on (i) an address request generated by the client device, and (ii) a determination as a result of the address request that the target device is a device with which a secure communication link can be established when the requested address is identified in an address lookup. The application program is configured and arranged so as to allow participation in audio/video communications with the target device over the secure communication link once the secure communication link is established. The signal processing configuration is arranged to execute the application program.

A network device stores an application program for a secure communications service and has processor configured to execute the application program. The execution causes the processor to send a request to look up an internet protocol (IP) address of a second network device based on an identifier associated with the second network device, to receive, following a determination by a name service that the second network device is available for the secure communications service, the determination by the name service being based on the identifier in the request: (1) an indication that the second network device is available for the secure communications service, (2) the requested IP address of the second network device, and (3) provisioning information for an encrypted communication link. The execution further enables the processor to connect to the second network device and to communicate data with the second network via the encrypted communication link. The network device is a device at which a user uses the secure communications service to access the encrypted communication link.

System and method for establishing an encrypted communication link based on IP address lookup requests

Systems and methods for connecting a first network device and a second network device over a communication network are disclosed. An exemplary method includes receiving, from the first network device, a request to look up a network address of the second network and evaluating the request to determine whether an identifier associated with the second network device is registered with a name service that facilitates resolving the identifier and further facilitates establishing direct encrypted communication links. It is determined whether the second network device is available to communicate through a direct encrypted communication link facilitated by the name service, the establishment of the direct encrypted communication link between the first network device and the second network device is facilitated. This includes provisioning the first network device or the second network device with one or more resources for the direct encrypted communication link. The established direct encrypted communication link carries encrypted data communicated between the first network device and the second network device, and the first network device is a user device.

Systems and methods for connecting network devices over communication network

A method for connecting a first network device to a second network device includes receiving a request to resolve a network address of the second network device. The request includes a name associated with the second network device that corresponds to the network address. The request is evaluated to confirm that the name is registered with a name service that facilitates resolving the name and facilitates establishing communication links, which use encryption, between the first network device and the second network device over the network. It is determined whether the second network device is available to establish the communication link. If so, the communication link is automatically established, including sending a signal to a provisioning server to provision the first network device or the second network device with a resource for the communication link.
