A New Scheme for Sealed Digital Signatures
Khaled Almgren · 2013
Nowadays, people are looking for the easiest way to do things. The digital world has made that even more possible. One aspect is the way when we sign documents and papers, how to present ourselves officially. When this aspect has been started to be a critical thing in the digital world, computer scientists started to conduct research of how it should be done. In an eye of users, digital signature should be easy to do, but on the eye of computer scientists, it has many problems and obstacles, security being the biggest. The problem of authentication has brought many issues, and many researchers have come with secure solutions but hackers made it unsecured. Since everything will be sent through an Internet, and knowing that the Internet is not a safe environment which brings many risks. This challenge has been more difficult and has gotten more complicated in every single day. Many schemes have presented efficient ideas but still more problems are coming. This paper will present a new scheme that uses a combination of old and new algorithms that brings more secure digital signatures. Moreover, we will first present issues on current schemes, and we will present our scheme and how it solved the issues presented in previous research work. Therefore, the paper will describe the scheme along with the algorithms that was used to achieve full data integrity for the digital signature. Also, it will describe a new mechanism to enhance the data transmit from users to any other sources by creating another digital signature that is based on the original digital signature.
