Abstract

Digital signatures are important for companies to overcome distance and time constraints. Therefore, a digital signature system is needed that is not only efficient but also has a high level of security to prevent data falsification or document legality. This research contributes to improving data security and integrity by implementing DSA and AES 128 Bit superencryption in the “Paperless Room” Digital Signature application. The implementation of the technology used is such as ReactJS, NodeJS, NextJS, cryptography modules in JavaScript, and PostgreSQL databases. Evaluation is done through penetration testing and measurement of encryption and decryption performance. The results show that this superencryption successfully improves efficiency and security, with an average encryption time of 165.67 ms and decryption of 98.17 ms, as well as an entropy value of 6.2837 which reflects a high level of security. In comparison, using DSA alone requires a longer encryption time of 242.97 ms and decryption of 312.83 ms, with a lower entropy of 4.8663. These findings confirm that DSA and AES-128 superencryption offer an optimal combination of efficiency and security for securing digital mail files in an enterprise environment.

Abstract

The Field Work Lecture was held in Hamlet One, Cinunuk Village, Wanaraja District, Garut Regency, West Java for 4 weeks starting from August 1 to August 31, 2022. Hamlet One, Cinunuk Village was the village chosen to be the KKN target village. The village's abundant potential is one of the main aspects of KKN implementation in order to increase village economic progress by developing tourist objects. KKN begins with village observations to see the potential of the village which will be the main target in the implementation of KKN. Sequentially designed programs start with discussions between KKN groups, village officials, and the local community, and specifically those that directly intersect with the designed programs. The implementation of the KKN program is carried out in a balanced manner starting with planning, implementation, and evaluation at the end of each program. The results achieved from the entire KKN program include developing community skills and helping to develop human resources to increase the potential of the local village. The literacy program is also implemented to improve the village economy by developing quality digital-based tourist objects. In the environmental field, the development of the promotion concept through digital platforms received a response and active participation from the residents of hamlet one, Cinunuk Village, Wanaraja District, Garut Regency, West Java.
