The present invention has particular applications to the navigation of Internet web pages using two-way interactive communication devices, such as a mobile device, a mobile phone, a landline telephone, and an Internet capable remote controller. According to one aspect of the present invention, each of the two-way interactive communication devices is a node in a distributed network, thus the devices can access hypermedia or hierarchic layers of information stored in server devices on the network. When one or more pages of information are updated, rather than sending the entire updated information to users of the devices subscribing to the updated information through the network, the present invention sends a notification to a proxy server that forwards the notification to the users using a messaging system via a low cost narrowband channel. Upon receiving the notification, the users can fetch the updates, when needed, through a wideband channel. Hence systemic solutions are provided in the present invention to integrate wideband and narrowband channels so as to keep the users informed of any updates to their desired information and meanwhile provide efficient means to the users for retrieving the latest updates without incurring uncontrollable costs and increasing unnecessary network traffics.

The present invention discloses a central certificate management system for thin client devices in data networks and has particular applications to systems having a large number of the thin clients serviced by a proxy server through which the thin clients communicate with a plurality of secure server computers over a data network. According to one aspect, the present invention provides a certificate management module that causes the server device to manage digital certificates for each of the thin client devices. To minimize the latency of obtaining certificates for each of the thin client devices, the certificate management module reserves a fixed number of free certificates signed by a certificate authority and their respective private keys in a certificate database and frequently updates the free certificate according to a certificate updating message. Whenever a user account is created for a thin client device, the certificate management module fetches one or more free certificates from the certificate database and associate the fetched certificates to the created account and meanwhile the certificate management module creates new free certificates with the certificate authority to fill in the certificate database. Apart from the tradition of obtaining certificates locally in client devices that normally have sufficient computing power, the present invention uses the computing resources in a server device to carry out the task of obtaining and maintaining certificates asynchronously in the proxy server and further. These and other features in the present invention dramatically minimize the demands for computing power and memory in thin client devices like mobile devices, cellular phones, landline telephones or Internet appliance controllers.

The second server device can then use the retrieved state information to accept a session with the client device.

In accordance with the present invention, a consumer communicates a request for purchase of goods and services to a merchant, the goods and / or services being selected from these listed together with their price quotes on the merchant's computer or website connected to a network, such as the Internet. The merchant then communicates a request for a token and an update key to the clearing server, the token being previously purchased by the consumer and residing on a clearing server device. The update key is used as an authorization to modify the value of the token, i.e., to decrement and to increment. The merchant forwards the purchased merchandise to the consumer. When consumer discontinues making purchases at the selected merchant, the merchant returns the updated token to the clearing server. A new key is necessary to make the next purchase. This is the case even where the requesting merchant is the same as that from whom the last purchase was made. When the token is requested, if the token was used after its initial purchase, the present value of the token is made certain by receipt on the clearing server of informational downloads from the merchants.

A method and system for communication between server-less computing devices or clients in computers communicating over networks, such as the World Wide Web (WWW) using stateless protocols, e.g., HTTP. In this scheme, there are two classes of clients which can operate independently or can be combined in computers communicating over the network: a) clients that issue commands and request status or data, and b) clients that function as service brokers for providing services and processing commands, updating status and providing specific data—resembleing a server device but without accessible TCP / IP ports. Each service providing device is authenticated, retains a unique identity and establishes a soft state with the globally accessible server or servers. All devices and clients can compile and process a globally common command language established between all communicating network clients. The central server includes a CGI processing program and a database to retain client specific information. The server database represents a collection of queues, each having a client unique identifiable status, pending commands and / or data components. In this scheme, commands and signaling transmitted between the servers and clients utilize standard HTTP protocol semantics and HTML or standard markup language syntax. Clients encapsulate or embed information as parameters passed to HTTP CGI as a set of standard HTTP conversations. A CGI processing program converts, parses or processes each conversation and passes arguments with or without data to queues.

A method and apparatus for efficiently processing data requests in a network oriented n-tier database environment is presented. According to one embodiment of the invention, certain or all data from the tables of a database server device can be maintained in tables on the client device in a client side database cache server system. This local cache allows the network oriented n-tier database system to eliminate the expense of repetitive network transmissions to respond to duplicate queries for the same information. Additionally, the local client device may also keep track of what data is cached on peer network nodes. This allows the client to request that data from a peer database cache server and off load that burden from the database server device. Moreover, the local client may also keep statistics regarding the frequency of requested data in order to optimize the data set maintained in the local database cache server.

A crypto-ignition process is needed to establish an encrypted communication protocol between two devices connected by an insecure communication link. The present invention introduces a method of creating an identical secret key to two communicating parties is conducted between a thin device and a server computer over an insecure data network. The thin device generally has limited computing power and working memory and the server computer may communicate with a plurality of such thin devices. To ensure the security of the secret key on both sides and reduce traffic in the network, only a pair of public values is exchanged between the thin device and the server computer over the data network. Each side generates its own secret key from a self-generated private value along with the received counterpart's public value according to a commonly used key agreement protocol, such as the Diffie-Hellman key agreement protocol. To ensure that the generated secret keys are identical on both sides, a verification process is followed by exchanging a message encrypted by one of two generated secret keys. The secret keys are proved to be identical and secret when the encrypted message is successfully decrypted by the other secret key. To reduce network traffic, the verification process is piggybacked with a session request from the thin device to establish a secure and authentic communication session with the server computer. The present invention enables the automatic delivery of the secret keys, without requiring significant computing power and working memory, between each of the thin clients respectively with the server computer.
