Digital Signatures Chain and El Gamal Scheme Integration for Data Transmission Integrity in Digital Transaction

Abstract

Digital signatures have been widely used by both private and government agencies. However, the use of chain digital signatures is still not widely used, especially in the military world. This results in a lack of ability to ensure data integrity, where it will be difficult to find out who has made changes to the document and to find out the original source of the document. This paper proposes a digital signature chain as a solution to guarantee data authenticity and prevent tampering during transmission. This technique involves creating a chain of digital signatures that are attached to data before it is sent over the network. The proposed method is expected to provide a more secure and efficient way to ensure data integrity, compared to traditional methods such as encryption and checksums. This paper evaluates the effectiveness of the proposed method through a series of experiments and shows that digital signature chains are an effective and reliable way to secure and maintain data transmission over networks. The proposed research aims to evaluate the effectiveness of digital signature chain technology in ensuring data security and integrity and to provide recommendations for its implementation
