Abstract: Security of data for any computer system application is vital and crucial since data is transferred via networks. Since Multimedia data encapsulates all types of data form structured text (fields and lines) through free text (pages, books …etc.) to images (still and moving), sound and all of them nowadays are digital. In this paper, a cryptography system is provided. It is based on the integration of two well-known algorithms, the public-key and the data encryption standard. The new integrated cryptography system incorporates a number of public and private keys. A new approach for generating secure keys is also adapted. This approach ensures high reliability secrecy. It also handles encrypted information efficiently such that attempts to break the coded messages will eventually fail. In addition, the new system extends the mapping character set by handling multilingual messages. Finally, some results of our experiments are presented.
