01 · A life in computing
The person behind the work
Leonard Adleman co-developed RSA with Ronald Rivest and Adi Shamir, contributing to a practical public-key approach to encryption and digital signatures. His research connects number theory, algorithms, and computational complexity. At the University of Southern California, he also pioneered DNA computing by demonstrating how molecular operations could solve a small computational problem. His career explores computation through both mathematical structures and unconventional physical media.
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.
