 Contrarian Minds: Sheueling Chang

"Generating RSA keys is quite time consuming. This is because each RSA key relies on having two very large prime integers. A computer must run for a long time to search for huge numbers that cannot be subdivided. Elliptic curve keys do not need to be prime, making it much easier to generate key pairs," Chang says. "If, for example, you need to issue smart cards for a health-care system to millions of customers, generating so many RSA keys on small token devices is not a trivial task."
