A chaotic-cipher-based packet body encryption algorithm for JPEG2000 images

作者：

Highlights：

• A chaotic-cipher-based encryption algorithm for JPEG2000 images is proposed.

• The algorithm produces a compliant JPEG2000 codestream.

• The algorithm relies on a 2-byte block encryption procedure for packet body data.

• A repeatedly encryption process is adopted to eliminate marker codes.

• The proposed algorithm is of high security and simplicity.
