Abstract: A method for authenticating a user to a computer system is disclosed, comprising using a first input and a second input in producing a digital signature in response to a challenge. The digital signature is valid when the first input matches a personalized secret and the second input matches a trio comprising a public modulus, a public exponent, and a private-key-dependent exponent. Selection of the personalized secret is discretionary and changeable. A crypto-key generation process uses the personalized secret and two primes as input to produce the trio. The public modulus and public exponent of the trio form a public key used in digital signature validation. Also disclosed is a business method that replaces the conventional public-key certificate with an agreement on the user's public key.

Abstract: This patent application discloses techniques, devices and systems for user authentication based on linking between a randomly generated authentication secret and a personalized secret.

Abstract: Techniques and systems for protecting verifiable digital secrets such as encryption keys and identification codes based on partition and recovery processes are described. Implementations of the present techniques may be used, for example, to offer individuals a personalized tool for protecting secret data and to provide enhanced security. The partition and recovery may be carried out at the same computer or on separate computers.

Abstract: Several processes and techniques for creating cryptosystems are disclosed. Cryptosystems created accordingly use a personalized secret such as a user-chosen password as a private key and a trio consisting of a first public exponent, a second public exponent, and a modulus as a public key. The public key and the private key form a public/private key pair. Selection of the personalized secret is discretionary and uses no information about the public key.

Abstract: The present invention creates flexibility into the RSA cryptography. The goal is achieved by allowing a user to select a personalized secret such as a password to derive an exponent that functions like a leading part of the RSA private key, and by further allowing the user to discretionarily change the selection without resorting to a regeneration of the public/private key pair. The invention also includes methods and cryptosystems of using a personalized secret and a crypto-key trio to produce and validate a digital signature. Exchanging a symmetric crypto key between two communication parties is one further application utilizing the devised techniques for the crypto-key generation, update, and validation.

Abstract: A structure of an EMI shield that can be easily installed to and removed from a base of an electronic equipment, where the base has at least one hook. The EMI shield comprises a casing for covering a circuit board on the base, wherein the casing includes a plurality of holes for thermal dissipation, and a plurality of flanges extending laterally from a bottom of a lateral side of the casing. The flanges comprise at least one groove to engage with the at least one hook of the base for positioning the EMI shield, and an opening, which is extended to a lateral side of the casing so that a power cord of the circuit board can be through the opening. At least one of the flanges comprises a spring finger, which is engageable with a concave portion of the base for fixing the EMI shield on the base without using screws.

Abstract: A method for crystallizing an amorphous film by using an electric field and an ultraviolet (UV) ray, and method for fabricating an LCD by using the same. The method for crystallizing an amorphous film includes forming an amorphous film having a catalytic metal deposited thereon on a substrate, irradiating a UV ray on the amorphous film, and applying an electric field to the amorphous film.

Abstract: An automatic monitoring and recording device for erythrocyte sedimentation employs a light source and a photodetector to detect the changes of light transmittance at the junction of plasma and red blood cell column. Changes of light transmittance at the junction reflect the descent of red blood cell column. The light source and photodetector pair is arranged so that it will track to the plasma - red blood cell column junction all the way the red blood cells fall. The whole course of erythroctye sedimentation is monitored and recorded automatically by a microcomputer.
