Schnorr-Signed ElGamal Encryption is an encryption mechanism commonly employed by various types of public-key cryptography (PKC) systems that blockchains and other types of networks employ. The framework is designed to hide sensitive data using Schnorr signature technology and is characterized by Diffie-Hellman key exchange and other complex mechanisms. The standardized Digital Signature Algorithm (DSA) that most blockchain systems are based on is a variant of the Schnorr and ElGamal signature frameworks. The Schnorr-Signed ElGamal Encryption scheme is named after its Egyptian creator Taher Elgamal, who proposed the solution in 1985.
