Secure communication in network environment is primary requirement to access remote resources in a controlled and efficient way. For validation and authentication in e-banking and e-commerce transactions, digital signatures using public key cryptography is extensively employed. To maintain confidentiality and digital envelope, which is the combination of the encrypted message and signature with the encrypted symmetric key, is also used. This paper has proposed to develop a hybrid technique using symmetric & asymmetric key cryptography. It will also include message authentication code to maintain integrity of message.
