The Design and Implementation of an Information Encryption and Hiding Tool
Abstract
In modern times, with the universal application of computers and rapid development of the Internet, more people have paid attention to the security issues in the Internet. The security issues mainly refer to network information security, so it needs some protection measures and provides appropriate security services. As the protection measures of information security, the encryption and information hiding technology provides the functions of integration, authentication, and non-repudiation for the signing message. In some applications, it only needs to be verified by some recipients while keeping the message secret from public. This paper mainly researches the information encryption and hiding technology and introduces the application prospects of the information security. Based on the acquired knowledge, a simple information encryption and hiding tool is designed, and it provides the functions of encryption and information hiding, and the handing object refers to the text and picture. The symmetric encryption algorithm is applied into the text encryption while a picture is hidden in another picture. The purpose of this design is to make the application of information encryption and hiding in real life understood, as well as to describe the principles of the technology on the whole. In addition, the designing result can be applied into the teaching and experiments.
