Unformatted text preview: : the Uniform Commercial Code, the United States Federal Reserve regulations, common law of contracts and signatures, the United Nations Convention on Contracts for the International Sale of Goods, and the United Nations Convention on International Bills of Exchange and International Promissory Committees. Included in the act are responsibilities and obligations of certification authorities, issues of liability, and limits and policies. In the United States, laws about signatures, contracts, and commercial transactions are state laws, so this model act is designed for states. The eventual goal is a federal act, but if this all begins at the state level there is less chance of the NSA mucking up the works. Even so, the validity of digital signatures has not been challenged in court; their legal status is still undefined. In order for digital signatures to carry the same authority as handwritten signatures, they must first be used to sign a legally binding document, and then be challenged in court by one party. The court would then consider the security of the signature scheme and issue a ruling. Over time, as this happened repeatedly, a body of precedent rulings would emerge regarding which digital signature methods and what key sizes are required for a digital signature to be legally binding. This is likely to take years. Until then, if two people wish to use digital signatures for contracts (or purchase requests, or work orders, or whatever), it is recommended that they sign a paper contract in which they agree in the future to be bound by any documents digitally signed by them [1099]. This document would specify algorithm, key size, and any other parameters; it should also delineate how disputes would be resolved.
