This paper presents a new cryptographic technique to prevent the repetitive terms in a message, when it is to be encrypted, so that it becomes almost impossible for a person to retrieve or predict the original message from the original message.In modern world, cryptography hackers try to break a code or cryptographic algorithm or try to retrieve the key, which is needed to encrypt a message, by analyzing the insertion or presence of repetitive characters in the message and encrypted message to find out the encryption algorithm or the key used for it. So it is must for a good encryption method to exclude the repetitive terms such that no trace of repetitions can be tracked down. For this reason we apply new cryptographic method that uses idea of dynamic key to exclude repetitive terms from a message, which is to be encrypted. In this method the repetitive characters are removed and there is no trace of any repetition in the message.The problem of distributing the secret key has been also overcome by adopting a new technique to hide the key inside the encrypted text in a nearly proposed way.
