Hellman said his work was initially discouraged by his colleagues until it was proven worthwhile, leading him to speak about the wisdom of foolishness during a lecture at Stanford University School of Engineering. Cryptography plays a crucial role in secure financial transactions, protecting a staggering number of financial transactions every day. Public key cryptography is essential to e-commerce and blockchains, he said. “Public key cryptography makes the seemingly impossible possible. Ideas seemingly stupid are often the best ideas, so technological innovation needs to be more tolerant of seemingly stupid ideas,” he said. |
