El Gamal algorithm

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 public key cryptography.

To fulfil both the functions of encryption and signature as the proposed immune based blind signeryption, the above signature schemes must be improved with a secure symmetric encryption/decryption algorithm, for which the typical ElGamal encryption algorithm is selected with its simplicity and security.
Compound scheme 1 is the scheme of blind signature^ Elgamal encryption; Compound scheme 2 is the scheme of ECDSA+ Elgamal encryption.
The classical ELGamal encryption scheme is one of the most widely used public-key cryptosystems.
