What does the 'S' in the RSA encryption algorithm stand for?

The "S" in the RSA encryption algorithm stands for Shamir, which refers to Adi Shamir, one of the three inventors of the RSA algorithm. Along with Ron Rivest and Leonard Adleman, Shamir played a crucial role in developing this widely used cryptographic algorithm in 1977. The RSA algorithm is named after the initials of their last names - Rivest, Shamir, Adleman - to honor their significant contributions in the field of modern cryptography.
