A practical design for secure broadcasting using PKD concept

Based on the concept of public key distribution (PKD), a new practical design for a secure broadcasting system is proposed. The proposed secure broadcast cryptosystem is based on the Diffie-Hellman public key distribution concept. The communication key is hidden with the RSA scheme. The security of the cryptosystem is therefore the same as that of the RSA scheme. The single key concept is used to reduce the load of additional control messages.<
