National: RSA Cryptographer Ronald Rivest Seeks Secure Elections the Low-Tech Way | Susan D’Agostino/Quanta Magazine
onald Rivest sports a white beard, smiles with his eyes and bestows his tech gifts on the people of the world. The Massachusetts Institute of Technology professor is the “R” in RSA, which means that he, along with Adi Shamir (the “S”) and Leonard Adleman (the “A”), gave us one of the first public key cryptosystems. It’s still common today: Nearly all internet-based commercial transactions rely on this algorithm, for which the trio was awarded the 2002 A.M. Turing Award, essentially the Nobel Prize of computing. In recent decades, Rivest has continued to work on making it computationally hard for adversaries to break a system, though he now focuses on ensuring that votes in democratic elections are cast as intended, collected as cast and tallied as collected. Elections, he has discovered, have stricter requirements than nearly any other security application, including internet-based commerce. Unlike online bank accounts and the customer names with which they are affiliated, ballots in an election must be stripped of voters’ names because of voting’s secrecy requirement. But the ballot box’s anonymity sets conditions for real or perceived tampering, which makes proving the accuracy of tallies important to voters, election officials and candidates. Another requirement is that voters can’t receive receipts verifying their candidate selections, lest the practice encourage vote selling or coercion. But without a receipt, voters might wonder if their votes were faithfully and accurately counted. It’s a tough problem to crack, and Rivest thinks the solution lies not with fancier computers, but with pen, paper and mathematics. “I mainly argue for some process by which we have confidence in our election results,” he said. “No one should say, ‘It’s right because the computer said so.’”Full Article: RSA Cryptographer Ronald Rivest Seeks Secure Elections | Quanta Magazine.
