Disclosed is a computer-readable medium containing program instructions for configuring a first computer so that a first telephony client on the first computer may securely communicate with a second telephony client on a second computer via a communication path. The computer-readable medium includes computer code for inserting a security algorithm within the communication path. The security algorithm facilitates secure communication between the first and second telephony clients such that more t...

Without the need to store and manage a private unique value of a hash function for each token, and without the fear of organizational private information of a center being revealed, a hash function is provided to a token. A unique value input unit is supplied with a unique value d, which is a parameter required to generate a hash function X. A message input unit is supplied with a message M from which to find a hash value. A function generation unique value memory unit 3 holds a function generat...

A mobile terminal for use in a mobile communications system includes a SIM card storing subscriber related data. For security, the SIM card performs secret cryptographic calculations with secret numbers. Secret information is hidden from outside observation by scheduling the calculations using a precomputed, fixed randomization schedule in such a way that externally observable parameters of the device cannot be associated to particular pieces, bits, symbols or values of the secret information.

An image input device which includes a means for inputting image data, a memory for storing a secret information and an operator for carrying out an operation by using the image data and the secret information.

In a signature creating apparatus, a clock generates a time stamp and in which time can be set only by a computer installed in a certificate authority center. Further, connecting sections connects an apparatus ID for specifying an apparatus and the time stamp and personal identification information for identifying an implementor to a plain-text so as to create data for the signature. A signature creating circuit encrypts the data for the signature using a signature creating key or the like and g...

An electronic processing device having GPS card and antenna, such as a laptop or personal digital assistant, can be enable only when a geographic-specific password is entered. Geographic regions are established in the electronic processing device with a user interface and priorities can be granted to the regions. The user further stores a geographic-specific password for each of the geographic regions. When the user travels and wishes to enable the electronic processing device, the GPS card and ...

Web based clients using embodiments of the disclosed invention may efficiently access stored manipulation functions in order to perform manipulation functions on data via Internet applications. The disclosed system allows web based applications to receive manipulation services on data using dynamically maintained, centrally stored, manipulation functions.

Systems are provided for the enhancement of the system BIOS for microprocessor-based devices. Before the end of a BIOS start-up procedure, the BIOS operation is diverted to a BIOS security authentication system which may be a portion of an enhanced system BIOS. The BIOS security authentication system establishes communication with an information module, if the information module is present. The information module is typically a removable or installable card, which may be unique to one or more us...

A disposable garment, subassemblies of the garment, and apparatus and methods for making the garment and subassemblies. The garment has elasticized leg and waist openings. The apparatus and methods of the invention facilitate assembling leg elastics and crotch elastics into the garment subassemblies, with the leg elastics extending across the width of the garment, and the crotch elastics extending along the length of the garment, while assembling a series of the garment subassemblies in a contin...

A superconducting magnet apparatus includes superconducting coils in a vacuum vessel. The vacuum vessel is provided with a refrigerator for cooling the superconducting coils. The refrigerator includes a motor drive, displacers, and a cooling cylinder accommodating the displacers such that the displacers may reciprocate therein. The vacuum vessel has a sleeve for accommodating the cooling cylinder while isolating them from its vacuum area, the sleeve having an opening near the wall of the vacuum ...
