| 20100014655 | Method and apparatus for generating cryptographic key using biometric data - A method of securely storing and authenticating biometric data against attacks of a third party includes encoding input biometric data, and applying a one-way function to the encoded biometric data. A first exclusive OR operation is performed to the result of the one-way function and a selected secret key. The result of the first exclusive OR operation is encoded, and a second exclusive OR operation is performed to the encoded result of the first exclusive OR operation and the encoded biometric data. The result of the second exclusive OR operation is stored. In the same manner, the biometric data is authenticated. Accordingly, the biometric data can be securely stored against the attacks of a third party by processing and storing the biometric data according to a predetermined procedure. | 01-21-2010 |

| 20090003476 | METHOD AND APPARATUS FOR DECODING USING COMPLEX LATTICE REDUCTION IN A MULTIPLE ANTENNA SYSTEM - A method and apparatus for Multiple-Input Multiple-Output (MIMO) signal decoding using complex Lattice Reduction (LR) in a multiple antenna system is provided. The method provides MIMO signal decoding with increased operating speed using a transformation of reducing the lattice basis directly to a complex channel matrix that has a smaller size in comparison with a conventional matrix, which decreases the computational complexity of the LR transformation, as well as using a procedure of permutating columns of the channel matrix only twice without binding to the procedure of reducing off-diagonal elements of the matrix R, namely prior and after the procedure of reducing. Moreover, the new method for MIMO signal decoding has its output soft decisions. | 01-01-2009 |
