A Multisecret-Sharing Scheme Based on LCD Codes - MDPI

WebIt is known that using bent functions to define binary codewords gives constant amplitude signals. Based on the concept of quarter bent functions, a new inequality relating the minimum order of terms of a bent function and the maximum Walsh spectral magnitude is proved, and it facilitates the generalization of some known results. WebThe determination of which sets of shares can be used to obtain the secret leads to the apparently new notion of minimal codewords in a linear code. It is shown that the minimal codewords in the dual code completely specify the access structure of the secret-sharing scheme, and conversely. disney hotels on property california

Secret Sharing Schemes from Two-Weight Codes Request PDF

Webcodewords in V with leftmost non-zero component 1 are minimal codewords. In an MDS code, the () N N-K+1 minimum-weight codewords with leftmost digit 1 are all the minimal codewords, as follows from the fact that any codeword of weight more than N - K … Web27 dec. 2005 · In this paper, a sufficient condition for all nonzero codewords of a linear code to be minimal is derived from exponential sums. Some linear codes whose covering structure can be determined are constructed, and then used to construct secret sharing schemes with nice access structures. WebBond, however, did not share her simple contentment. The loyal pooch had been ill at ease ever since Loid and Anya had left, wearing a path in the rug where he’d paced the length of the apartment. Once or twice he’d interrupted her work, tugging on her leg and earning both a scolding and small piece of meat to appease him, only for him to return. coworking macclesfield

"Web1 sep. 2024 · The minimal codewords of a linear code are those whose supports, i.e., the sets of nonzero coordinates, do not properly contain the supports of other nonzero codewords. They are equivalent to circuits in matroids and cycles in graphs. In coding theory, minimal codewords were first used in decoding algorithms [1], [2], [6], [15].
