Design and Implementation of Information Digest Algorithm on a Ternary Optical Computer

In order to explore the information security field of ternary optical computers, this paper designs a new message digest algorithm based on the characteristics of ternary binary logic operations of ternary optical computers. And after demonstration and analysis, its security is greatly improved compared with the message digest algorithm designed based on binary and ternary values, which gives full play to the advantages of ternary optical computers.
