What is Schnorr-Signed ElGamal Encryption?

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.
