ABSTRACT
In 1977, the RSA cryptosystem was proposed by Ron Rivest, Adi
Shamir, and Leonard Adleman of the Massachusetts Institute of
Technology (MIT). RSA was patented in the United States by MIT
on September 20, 1983. Although the patent for RSA expired
September 21, 2000 [254], RSA has become the most popularly
implemented public-key cryptosystem.
