摘要： An apparatus including circuitry configured to receive a plurality of images and extract at least one iris image from each of the plurality of images. The circuitry is configured to receive a claimed identity iris image corresponding to an identity to be authenticated, normalize the iris images and the claimed identity iris image, and filter the normalized extracted iris images to select a subset of the normalized extracted iris images based on a similarity measurement relative to the normalized claimed identity iris image. The circuitry is configured to divide the normalized claimed identity iris image and each image of the subset of images into a plurality of sub-images, filter the sub-images to select the sub-image having a closest similarity measurement relative to a sub-image of the normalized claimed identity image in a corresponding sub-image position to the selected sub-image, and generate a composite iris image by fusing the selected sub-images.

摘要： The virtual account and token-based digital cash token protocols use a combination of blind digital signatures and pseudonym authentication with at least two pairs of public and private keys. A user has one master pair of private and public keys and many pseudonym pairs of private and public keys. The new protocols combine blind digital signature and pseudonym-based authentication. Blind digital signatures based on the master pair of keys are used to withdraw digital cash from the user's bank account under the user's real identity. A pseudonym pair of keys is used for depositing digital cash with a digital cash issuer. Pseudonym key pairs are used for spending the digital cash. Digital cash includes digital cash tokens in virtual accounts, which can be managed from a user's fixed or mobile computing platform.

摘要： The RSA-analogous XZ-elliptic curve cryptography system and method provides a computerized system and method that allows for the encryption of messages through elliptic polynomial cryptography and, particularly, in a manner which is analogous to RSA cryptography but which does not require multiple private keys, as in the RSA scheme. The RSA-analogous XZ-elliptic curve cryptography method is based on the integer factorization problem. It is well known that the integer factorization problem is a computationally “difficult” or “hard” problem.

摘要： The hash functions with elliptic polynomial hopping are based upon an elliptic polynomial discrete logarithm problem. Security using hash functions is dependent upon the implementation of a computationally hard problem, and the elliptic polynomial discrete logarithm problem provides enough relative difficulty in computation to ensure that the produced hash functions, as applied to message bit strings, are optimally secure. The hash functions are produced as functions of both the elliptic polynomial as well as the twist of the elliptic polynomial, particularly using a method of polynomial hopping.

摘要： The message authentication code with elliptic polynomial hopping provides methods for the generation of message authentication codes (MACs) utilizing elliptic curves, which are based on the elliptic curve discrete logarithm problem. The elliptic curve discrete logarithm problem is well known to be a computationally “difficult” or “hard” problem, thus providing enhanced security for the MACs. Different elliptic polynomials are used for different blocks of the same plaintext, each elliptic polynomial for each message block being selected at random using an initial secret key and a random number generator.

摘要： The hybrid virtual account and token-based digital cash protocols provide a user with many pairs of secret and public keys. One of the pairs is the master pair, which consists of one master user private key and one master user public key. Other pairs are pseudonym pairs, wherein each consists of one pseudonym user private key and one pseudonym user public key. The use of a master key pair and pseudonym key pairs circumvents the need for blind signatures. None of the invention's protocols require blind signatures. The protocols comprise public key protocols, digital signatures and symmetric key protocols.

摘要： The cryptographic hash functions using of elliptic polynomial polynomials are based on the elliptic polynomial discrete logarithm problem, which is well known as a computationally hard problem. The hash functions are based on the elliptic polynomial equation in their generation, where different elliptic polynomials are used for different blocks of the same plain text. Particularly, the hash functions use an elliptic polynomial with more than one independent x-coordinate. More specifically, a set of elliptic polynomial points are used that satisfy an elliptic polynomial equation with more than one independent x-coordinate which is defined over a finite field F.
