RSA ENCRYPTION FOR DATA SECURITY IN QR CODE BASED DIGITAL PAYMENT SYSTEM
Keywords:
Digital Payment, QR Code, RSA, Key GeneratorAbstract
This research, titled "RSA Encryption for Securing Data in QR Code-Based Digital Payment Systems," aims to enhance transaction data security in the increasingly popular digital payment environment. In today’s digital era, the use of cashless payment methods through applications such as OVO, DANA, and GoPay simplifies transactions but also introduces risks related to data security. Therefore, a solution is needed to ensure the confidentiality and integrity of data. In this study, the RSA (Rivest-Shamir-Adleman) algorithm is employed to encrypt transaction data before it is embedded in a QR Code format. This process involves the generation of public and private keys, data encryption, and the creation of a unique QR Code for each transaction. The results indicate that using RSA with a 2048-bit key length provides a high level of security, effectively protecting data from unauthorized access and ensuring data integrity throughout the transmission process.Based on the analysis, the integration of RSA encryption and QR Code technology proves to be effective in mitigating data theft risks. This research is expected to serve as a reference for the further development of more secure digital payment applications, while also offering insights into the real-world application of cryptography.
