Abstract: A method for information reconciliation in quantum key distribution is introduced herein. In general, a first binary sequence belonging to a sender is being divided and fitted into a first blocks system having a specific number of blocks (103). At the same time, a second binary sequence belonging to a recipient is being divided and fitted into a second blocks system having the same specific number of blocks as the first blocks system (103). The first blocks system and the second blocks system correspond to each other. Parity bit comparison is then carried out between the blocks within the first blocks system and their corresponding blocks within the second blocks system to detect an error that is defined as parity bit discrepancy (107). Once detected, a matrix system within the error block of each first and second blocks systems is extracted, and parity bits of each row and each column of the matrix system within the error block of the first blocks system are compared to the parity bit of its corresponding row and column of the matrix system within the error block of the second blocks system to identify and correct the entry contributing the error (108).

Abstract: The present invention provides an apparatus for measuring six polarization state of an input optical pulse. The disclosed apparatus is easy to implement with relatively lesser components to form the apparatus. The apparatus uses two polarization rotators (231, 232) having a respective non-linear material (221, 222) that are oriented at different angles. The two polarization rotators are connected in series for the polarization state on an input optical pulse and a beam splitter is connected thereafter to direct the rotated pulse to either a horizontal or a vertical detector.

Abstract: A method for performing quantum key distribution wherein in the sender and receiver agreeing the states and sets, three non-orthogonal states (6) are selected from three respective bases, one state from each basis being selected to represent a key value, and three sets (10) are then produced by grouping (8) the states into sets of two non-orthogonal states.

Abstract: Bijective substitution box is constructed from non-permutation power functions wherein said non-permutation functions are optimally converted to a permutation function by utilizing the heuristic algorithm of an Optimized Balanced Boolean Function Maker algorithm such that it has high cryptographic properties. The result is a bijective function, which provides desirable cryptographic properties such as high nonlinearity of 108 and high algebraic degree of 7. The said construction of bijective substitution boxes from non-permutation power functions using heuristic techniques comprising steps of first selecting a Boolean map from a plurality of linear power functions and high cryptographic properties power function (102, 104); extending an image of said extended image by utilizing Optimized Balanced Function Maker algorithm (110); and performing analysis on cryptographic properties of substituted box (112). The said steps are iterated until said cryptographic properties meets the predetermined condition of a cryptographically strong bijective substitution box.

Abstract: A method for processing information in wireless communication having optically coupled first and second channel stations comprising the steps of determining and executing the error correction on the string developed through the quantum channel and generating a predetermined string by using a specific check sum after the error correction which shrinks the corrected string into a useful predetermined message the first channel station intends to transfer to the second channel station.
