A system for actively updating a cryptography module in a security gateway and related method is used in a security gateway, such as a VPN gateway according to an IPSEC protocol, which is connected between at least one user computer system and a network system. The system includes a Web GUI, a module update unit, a defined module unit, and an extended library. A user can easily update or add decryption / encryption modules into the extended library of the gateway through the Web GUI and the module update unit instead of updating the decryption / encryption modules along with the entire kernel firmware. This can reduce the setting time, increase the efficiency of operation, reduce the maintenance cost, and promote the expansion of decryption / encryption modules of the gateway so that network transmission can become much safer.

An information terminal of a user B who permits a user A to search the person B calculates a calculation result G(Pa′, Pb) by using information Pa′ related to the user A and information Pb of the user B, both Pa′ and Pb being stored in the information terminal of the user B and transmits to a server the calculation result G(Pa′, Pb). Further, the information terminal of the user B receives trust information expressing that Pb is authenticated and calculates a calculation result F(Pb) and transmits to the server. The information terminal of the user A calculates G(Pa, Pb′) and transmits it to the server. When the server receives G(Pa, Pb′) from the information terminal of the user A, the server searches G(Pa′, Pb) which matches G(Pa, Pb′) and the search result with F(Pb) to the information terminal of the user A. The information terminal of the user A calculates F(Pb′) and compares it with F(Pb) which is sent by the server.

The invention discloses a multi-website shopping cart implementation method, which uses a main website to provide consumers a hyperlink element linking to an associate website. When a consumer selects the hyperlink element, the main website will transmit the ID of the consumer and the verification code to the associate website so as to verify the identity of the consumer. When the consumer wants to purchase a particular commodity sold at the associate website, the main website will receive trade information transmitted from the associate website and thereby charge to the consumer. Finally, the main website places an order to the associate website and provides the name and the address of the receiver to the associate website. With the trade information, the name and the address of the receiver, the associate website sends out the commodity. The invention also discloses a multi-website shopping cart system to implement the above method.

A private communication network through which a plurality of member users communicate using the public switched telephone network (PSTN) is disclosed herein. Each member user utilizes either a modified land line telephone directly connected to PSTN, or uses a modified mobile telephone operatively coupled to the PSTN through a wireless communication system. The private communication network includes network call manager having a telephone network interface for establishing a telephone connection with each of a plurality of telephone lines of the PSTN. Each of the plurality of telephone lines is associated with one of the plurality of member users. The network call manager further includes a switch matrix, coupled to the telephone network interface, for providing an information signal received from an active member user over a selected telephone line to the remaining non-active member users.

A method and system for file-system based caching can be used to improve efficiency and security at network sites. In one set of embodiments, the delivery of content and storing content component(s) formed during generation of the content may be performed by different software components. Content that changes at a relatively high frequency or is likely to be regenerated between requests may not have some or all of its corresponding files cached. Additionally, extra white space may be removed before storing to reduce the file size. File mapping may be performed to ensure that a directory within the cache will have an optimal number of files. Security at the network site may be increased by using an internally generated filename that is not used or seen by the client computer. Many variations may be used is achieving any one or more of the advantages described herein.
