Abstract: Cryptographic devices that leak information about their secrets through externally monitorable characteristics (such as electromagnetic radiation and power consumption) may be vulnerable to attack, and previously-known methods that could address such leaking are inappropriate for smartcards and many other cryptographic applications. Methods and apparatuses are disclosed for performing computations in which the representation of data, the number of system state transitions at each computational step, and the Hamming weights of all operands are independent of computation inputs, intermediate values, or results. Exemplary embodiments implemented using conventional (leaky) hardware elements (such as electronic components, logic gates, etc.) as well as software executing on conventional (leaky) microprocessors are described. Smartcards and other tamper-resistant devices of the invention provide greatly improved resistance to cryptographic attacks involving external monitoring.

Abstract: A firearm safety system restricts the use of the firearm by reference to biometric data received by a sensor coupled to the firearm trigger. The biometric data is compared to at least one record of biometric data associated with a permitted user to determine whether firearm actuation is permitted. Firearm actuation is controlled by an anchor that is pivotally coupled to the firearm trigger. Firearm actuation is prevented when the anchor is extended between the trigger and the trigger aperture. Firearm actuation is permitted when the anchor is retracted in response to a positive identification by the sensor.

Abstract: A method and system sends documents from a desktop computer inside an intranet through a series of firewalls and/or proxy servers to a server residing on the Internet. A computer in an intranet system protected by a firewall or proxy server uses a software application to access the Internet. The software also encodes binary data to be sent as text. This binary data may be subdivided into smaller text packets. The text packets are sent, using HTTP, to a server outside the firewall, which has been configured to accept such text packets. The server converts the text packets back to the original binary data representation. The binary data, once resident on the internet server, can then be forwarded directly to other internet servers, internet desktop computers, printers, or fax machines.

Abstract: A method is disclosed for creating a design that appears to float in the face of a piece of material. A piece of fusible material is placed on top of a first piece of material. The fusible material is coated with an adhesive. The non-adhesive side of the fusible material is in contact with the face side of the first piece of material. The fusible material is sewn to the first piece of material. The stitches define the periphery of an unbroken design. The fusible material is trimmed outside the periphery of the unbroken design. Next, the fusible material and the fabric are trimmed inside the unbroken design to create an aperture. The fusible material is pulled through the aperture so that the adhesive is substantially interposed between fusible material the reverse side of the first piece of material. The fusible material is then fused to the reverse side of the first piece of material. A second piece of material is placed on the reverse side of the piece of fabric to cover the aperture.

Abstract: A tape measuring device for determining bra sizes has dimension and size markings on both the outer and inner surfaces of the tape. The dimension markings divide each surface by standard units and subunits of length—typically inches. The size markings on the outer surface allow the user to determine the proper band size for a bra based on a single measurement, without the need for any additional calculations. The size markings on the inner surface allow the user to determine the proper cup and overall bra size based on the band size determination and a measurement of circumference around the bust, again without the need for any additional calculations.

Abstract: A method and apparatus is provided for effecting secure document delivery in any of various document formats. A document is encrypted with the public key of a server associated with the recipient of the document, instead of with the public key of the intended recipient. The receiving server is located within a firewall. The encrypted document is forwarded to the server within the firewall. The server decrypts the document using its corresponding private key, converts the document to a now data representation, and then either forwards the document to the recipient inside the firewall, or re-encrypts the document with the public key of an intended recipient outside of the firewall or with the public key of another server that is associated with the intended recipient of the document.

Abstract: A racquet string comprises of a core surrounded by at least one sheath, having a plurality of sheath fibers wound around said core, and a coating resin uniting the core and sheath fibers into a unitary body. The sheath fibers are helically wound about the core at a high wind angle, i.e., at a wind angle between 25 and 40 degrees relative to the core axis. Preferably, the sheath comprises a plurality of main sheath fibers and a plurality of non-main sheath fibers, and the core, the main sheath fibers, and the coating resin are transparent. Preferably, the non-main sheath fibers have a relatively low transparency. In this manner, the non-main fibers produce a multi-helix appearance when the string is observed from the side.

Abstract: Cryptographically assured data structures are created to enable a single sign on and/or authentication method for securely transferring user authentication information from a first computer to a second computer to allow the user to seamlessly interact with the second computer without necessarily re-authenticating himself thereto. Thus, if a second computer trusts the methods used by a first computer to authenticate a user, then the second computer can use a cryptographically assured cookie created by the first computer to authenticate the user, without requiring the user to perform an explicit authentication step at the second computer. More particularly, a cryptographically assured cookie is made by creating a cryptographically assured voucher of a user characteristic at the first computer, and embedding the voucher into a cookie for transmission to the user's computer and hence to the second computer.

Abstract: The present invention provides a method and apparatus for securing cryptographic devices against attacks involving external monitoring and analysis. A “self-healing” property is introduced, enabling security to be continually re-established following partial compromises. In addition to producing useful cryptographic results, a typical leak-resistant cryptographic operation modifies or updates secret key material in a manner designed to render useless any information about the secrets that may have previously leaked from the system. Exemplary leak-proof and leak-resistant implementations of the invention are shown for symmetric authentication, certified Diffie-Hellman (when either one or both users have certificates), RSA, ElGamal public key decryption, ElGamal digital signing, and the Digital Signature Algorithm.
