With the the rapid development of the Internet technology， multimedia technology and network， various kinds of multimedia information can be spreaded conveniently and fastly in different forms on the Internet ，and also， daily communication about economic， military and politics can be exchanged through the multimedia However， the multimedia information transmission also has great potential security Some criminals use technical means to steal and destruct multimedia information maliciously ，which brings huge loss to the multimedia information Well，The digital image is an important part of multimedia Research on digital image encryption has excellent significance to protect the interests of holders and enhance the harmony of economy society’s development As a result， how to protect the security of digital image， has gradually become the focus of The content of the subject is based on the structural features of digital image to research digital image information The purpose of this project is to achieve image information security algorithm，which has high security， to the realize of digital image encryption， That means a clear image can be changed into a unrecognized ciphertext using a certain algorithm to avoid the exposure of the original image during the network Image encryption has a variety of algorithms， this paper takes the hybrid encryption of Hilbert curve and Henon mapping，and meanwhile， realize changing of spatial pixel scrambling and gray scale of digital Encryption example shows that the encrypted image has completely covered the contents of the original image and the encryption effect is Therefore， the hybrid encryption based on the Henon mapping and Hilbert curves is a safe， effective， fast encryption Keywords: digital image; image encryption; pixel scrambling; gray transformation; Henon Hilbert curve mapping;
