A Data Structure for Integrity Protection with Erasure Capability

NIST Inventors

D. Richard Kuhn

Provided is a process including: initializing a data block matrix; making supra-diagonal nodes that include at most one more node than sub-diagonal nodes; making a hash nodes with a hash sequence length that is proportional to a number of nodes in the row or column of nodes in which the hash node is

Diagonal Node Data Block Matrix for Adding Hash-linked Records and Deleting Arbitrary Records While Preserving Hash-based Integrity Assurance

NIST Inventors

D. Richard Kuhn

The invention is a data structure, referred to as a block matrix, that uses an array of blocks with hash values for each row and column. The invention supports the ongoing addition of hash-linked records while also allowing the deletion of arbitrary records, preserving hash-based integrity assurance

Oracle-Free Match Testing of a Program Using Covering Arrays and Equivalence Classes

NIST Inventors

D. Richard Kuhn and Raghu N Kacker

A process for testing a program includes: receiving a variable comprising a plurality of input values; producing a plurality of equivalence classes for the input values; producing a representative value per equivalence class; producing, by a processor, a primary covering array comprising a plurality
