The Legacy of RSA Encryption: How MIT Mathematicians Transformed Digital Security

The Story Behind RSA Encryption: How Three MIT Mathematicians Revolutionized Digital Security

In 1977, three brilliant minds at MIT - Ron Rivest, Adi Shamir, and Leonard Adleman - filed what would become one of the most important patents in computer science history: Patent 4,405,829, better known as the RSA encryption system.

Before RSA, secure digital communication faced a seemingly impossible problem: how do you share secret information with someone you've never met, over a channel that anyone can intercept? The answer lay in the elegant mathematical properties of prime numbers.

RSA created the world's first practical public-key cryptosystem - a revolutionary "digital lock" that anyone could use to encrypt messages, but only the intended recipient could unlock. This breakthrough solved the fundamental key distribution problem that had plagued cryptographers for decades.

Today, RSA encryption is everywhere:
• Every secure website you visit (that little padlock icon)
• Online banking and credit card transactions
• Secure messaging apps
• Digital signatures and certificates
• Cryptocurrency transactions
• Government and military communications

The patent expired in 2000, releasing this crucial technology into the public domain and accelerating the growth of e-commerce and secure digital communications. Without RSA, the modern internet as we know it simply wouldn't exist.

This is the fascinating story of how three mathematicians used the power of prime numbers to change the world forever, enabling billions of secure transactions every single day.
