A popular asymmetric encryption algorithm invented by Taher El Gamal in 1985. Named after its author and based on discrete logarithms, El Gamal is used for encryption and digital signatures. See ...

Shor's algorithm would allow a quantum computer to solve factoring problems (used by the RSA algorithm), the discrete logarithm problem (used by the El Gamal algorithm) and even certain versions of ...

Encryption is a key technology for federal agencies. Although encryption is the primary goal, many encryption systems depend on a combination of tools to accomplish other tasks. Public-key ...

Researchers at Tel Aviv University have developed a compact, untethered tool capable of extracting GnuPG crypto keys (RSA and ElGamal) from laptops. It’s unlikely that anyone envisioned the evolution ...
