Embodiment Construction
[0031] The implementation process of the present invention will be further described in detail below in conjunction with specific drawings and examples.
[0032] figure 1 is the encryption flowchart of this method, figure 2 is the decryption flowchart of the method.
[0033] The programming software used is MyEclipse 2015 CI, select image 3A Lena image of size 512×512 is shown as the original interaction image. Using this method, Alice describes the detailed process of encrypting the interactive image as follows:
[0034] Step 1: Use the hash algorithm SHA-256 to get the 256-bit hash value corresponding to the original image K =9ae48c65bb78a5c6d0d9496f9364f36efc2bd2f2a3f521763e16edc434977e9e (hexadecimal representation), calculate the initial value of the PLCM chaotic map shown in formula (1) x 0 =0.447058823529412 and parameters q =0.352941176470588, iterate formula (1) 512×512 times to generate a chaotic sequence X ={ x i} 262144 .
[0035] Step 2: Alice calc...
