In modern computer science, secured data communication in an efficient way is one of the challenging aspects. To achieve an advanced level of security this paper introduces a new algorithm for symmetric-key cryptography. The main novelty of this paper is to convert the plaintext into its equivalent cipher-text of unprintable characters using ASCII and radix conversions. To achieve a higher level of security a 128 bit i.e., 16 characters symmetric-key has been used. Dividing the original message into several packets the symmetric-key is imposed with each packet and then using radix conversion the plaintext is converted to unprintable cipher-text. The proposed cipher is an efficient and novel procedure to secure data communication which offers a higher level of security without increasing the size of data or loosing of any data. Download
