WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebElGamal Cryptosystem Like RSA, ElGamal is a public key cryptosystem: The encryption key is published, and the decryption key is kept private. This allows an entity (human or …
WebApr 12, 2024 · The El Gamal encryption algorithm, based on the Diffie-Hellman key exchange, was developed by Taher Elgamal in 1985. The security strength of this algorithm is based on the difficulty of solving discrete logarithms. One downside is that the ciphertext generated by El Gamal is two times the length of the plaintext.
