A Strong Secured Message Transaction System using RSA, Triple-DES and Enveloped Data Systems

Secured message transactions are considerably demanding issues for any electronic transactions system. A strong secured message communication system has been designed, developed and implemented using JAVA programming languages. For this, RSA is used as public key, Triple-DES is used as private key cryptographic technique and the enveloped data is used ensure better security in the proposed system. First the public-key algorithm RSA and private key cryptography technique Triple-DES jointly employed on the intended message to produce improved cipher text message. Then another cryptographic process enveloped data is applied on the produced cipher text that finally creates strong scramble message that is sent to the destination. This can be applied on any length of secured message transactions in any cryptographic applications where needed
