With the increasing volume of digital information the cost of encryption is also increasing as conventionally the whole information is encrypted. But it is possible to provide equal security by partially encrypting the information, which will reduce the computation cost. In this paper authors proposed a partial encryption scheme based on bit plane manipulation. The proposed scheme encrypts only those bits which carry significant amount of information instead the whole image. The scheme uses DNA computation and chaotic henon map which are run on low computational overhead. Therefore, the scheme runs on low computational overhead. Moreover, the values of UACI and NPCR of the partially encrypted image is better than that of AES and some other schemes.
