Schnorr-Signed ElGamal Encryption

Schnorr-Signed ElGamal Encryption is a commonly adopted encryption technique utilized in multiple public-key cryptography (PKC) systems employed by blockchains and other networks. This method incorporates Schnorr signature technology, along with complex mechanisms like Diffie–Hellman key exchange, to ensure the protection of sensitive data. The standardized Digital Signature Algorithm (DSA), which serves as the basis for most blockchain systems, is a variant of the Schnorr and ElGamal signature frameworks. The credit for this encryption scheme goes to Taher Elgamal, an Egyptian cryptographer who proposed the solution in 1985 and after whom it is named.
