  • Verification System and Method with Extra Security for Lower-Entropy Input Records
    Publication number: 20140245020
    Abstract: An authentication system for digital records has a hash tree structure that computes an uppermost, root hash value that may be digitally signed. A random or pseudo-random number is hashed together with hash values of the digital records and acts as a blinding mask, making the authentication system secure even for relative low-entropy digital records. A candidate digital record is considered verified if, upon recomputation through the hash tree structure given sibling hash values in the recomputation path and the pseudo-random number, the same root hash value is computed.
