Abstract

We propose an encryption scheme which uses steganography. The encryption algorithm encrypts messages by embedding them in a data stream in such a way that an adversary cannot get information about the messages. Since the embedding is the only computation requires this scheme is optimal in computational efficiency. However, since the size of the data stream is large, this scheme is most beneficial when the cost of bandwidth is less expensive than the cost of computation. The scheme embeds the message as specified by a pseudo random generator. Therefore, the scheme'"'"'s security is based on a new weak assumption base on the pseudo random generator which we introduce.
