In this paper we demonstrate a new proposed hybrid cryptosystem, which combines the one-time pad that is theoretically unbreakable cipher, with the most strong (standard) encryption algorithms today’s, the RSA public-key algorithm, and the AES standard secret-key algorithm, to offer unconditionally secured cryptosystem. Public-key cryptosystem can be used to create a digital signature. The analysis of the proposed scheme shows that with a digital signature, we can be sure the sender and the receiver cannot deny the signed object, and we can ensure the message integrity. The existence of such a system would enable instant secure communication between subscribers who have never met or communicated before. A system of this kind greatly simplifies the problem of key distribution. A one-time pad, under the assumption that it has been exchanged between parties’ securely, offers unbreakable cipher! Besides, the proposed scheme facilitates additional level of security strength achieved through the involvement of a four level of key-hierarchy.
