The person behind the work
Adi Shamir co-invented the RSA public-key cryptosystem with Ronald Rivest and Leonard Adleman during their collaboration at MIT. His broader research includes secret sharing, cryptanalysis, and the mathematical foundations of security. At the Weizmann Institute, he continued to investigate both the construction of cryptographic systems and attacks that reveal their limits. His work illustrates how designing protection and understanding weaknesses advance together.
The contribution, explained
Ronald Rivest, Adi Shamir and Leonard Adleman developed RSA. Public information can be used to encrypt a message, while a related private key enables decryption. The construction uses number-theoretic operations with deliberately different computational roles, and it also supports digital signatures.
Why it matters
Public-key techniques made it possible to establish secure relationships without first sharing the same secret key.
