"Web1.1 Background of Public-Key Cryptosystems and Related Works Until the late 1970's, the only cryptosystems for message transmission were symmetric key systems. In symmetric key cryptography, any two users who require communicating a message must have a same key to cipher or decipher the message. In 1976, Diffie and Hellman [14] invented a key- " - Elements of cryptosystems ins
