Abstract: A new ElGamal public key cryptosystem and digital signature scheme are presented over algebraic integral rings of quadratic number fields. Their securities depend on difficulty of discrete logarithmic computations in the algebraic integral rings.

Key words: ElGamal Public Key Cryptosystem(PKC), digital signature scheme, algebraic integral ring
