Strong Digital Signatures: The Lamport Advantage

Signing and claiming ownership of data is a basic act in cyber space, especially to approve financial transactions, and verify critical instructions. The prevailing signatures today are based on algorithmic complexity, which is essentially a cryptanalytic minefield - vulnerable to weaponized math. Alternatively, we can rely on lavish use of randomness, and resurrect pre-complexity solutions. The forgotten Lamport signature is attracting new interest.
