The Role and the Impact of Digital Certificate and Digital Signature in Improving Security During Data Transmittion

Abstract

This paper is cryptographic oriented research, aiming to describe the notion, role and impact of digital signature and digital certificate for the wide audience. Security improvement during data transmission comes as a result of the huge growth of electronic communications. While one party is trying to secure these data, there is always another party trying to reach and use them in several cases, so understanding the importance of digital security is quite important for everyone using a computer nowadays. Thus, the research explains the need for these types of technologies. Reading the paper, you will meet a comparison between paper and digital signature and digital certificate compared to digital signature. During this research were used Observational and Correlational research methodologies. As a conclusion, we can say that electronic signatures and certificates are making life easier for organization leaders, HR and all of other company sectors in a variety of industries, allowing them to freely announce, communicate or exchange several documents or high sensitive data.
