Efficient Zero-knowledge Authentication Based on a Linear Algebra
We propose a new Zero-knowledge scheme based on MinRank. We prove he used the same X S and T. Finally when Q = 0 we will verify the rank of the.

Polynomial Time Algorithm for Min-Ranks of Graphs with Simple
The task of computing the min-rank of a graph is accomplished when the computation reaches the root of the compound tree Let F P(c) roughly speaking denote the family of graphs with simple tree structures where each node in the tree structure is connected to its child nodes via at most cvertices
Optimal Index Codes with Near-Extreme Rates - arXivorg
for ?nding min-ranks over the binary ?eld of digraphs were developed in the work of Chaudhry and Sprintson [13] The min-ranks of random digraphs are investigated by Haviv and Langberg [14] A dynamic programming approach was proposed by Berliner and Langberg [15] to compute min-ranks of outerplanar graphs in polynomial time Algorithms
