Digital Signature Laws

The Right Approach
New Legal Status For Digital Record Keeping
The Challenge Of Document Integrity
Last summer, President Clinton signed S.761, also know as "E-Sign," into law. Formally titled the Electronic Signatures in Global and National Commerce Act, E-Sign is colloquially known as the "digital signature act" and has been widely hailed as a boon to e-commerce.

E-Sign did not spring fully formed from the mind of Congress. It derives from, and shares much language in common with, UETA, the Uniform Electronic Transactions Act, which a majority of states have either already adopted, or are considering.

The PKI (public key infrastructure) industry has made what marketing hay it can of E-Sign. But the fact remains that, while E-Sign certainly confers a stamp of approval on PKI, this set of technologies is as complex and esoteric as anything the high-tech industry has ever created. There's a huge disconnect here. Although I'm a proponent of digital signatures, and have used and advocated them for years, PKI remains a complete mystery to most people.

Like UETA before it, E-Sign does not try to define digital signatures except in abstract and technology-neutral terms:

UETA definition of electronic signature:

(8) "Electronic signature" means an electronic sound, symbol, or process attached to or logically associated with a record and executed or adopted by a person with the intent to sign the record.

E-Sign definition of electronic signature:

The term "electronic signature" means information or data in electronic form, attached to or logically associated with an electronic record, and executed or adopted by a person or an electronic agent of a person, with the intent to sign a contract, agreement, or record.

While E-Sign general seeks to avoid pre-empting states' UETA efforts, it appears to threaten at least one state -- Utah -- whose Digital Signature Act tries to spell out an explicit integration of PKI into state government.

In this volume of Best of BYTE, we explore the emergence of some heuristic algorithms. Although we have only scratched the surface of this intriguing subject, we hope we've suggested the potential of the synthesis of heuristics and algorithms.
