Abstract
RFID technology plays a critical role in item identification, tracking, asset management, anti-counterfeiting, and wireless communication, significantly enhancing productivity. However, the security of the wireless communication link between electronic tags and readers is a growing concern, limiting wider adoption. Ensuring secure electronic tag authentication is essential.This paper focuses on implementing a system to encrypt electronic tags using digital signature algorithms like Elliptic Curve Cryptography (ECC) and RSA. It compares these methods in terms of signature computation time, memory usage, and key length, highlighting their advantages and limitations. The paper begins by detailing the components, principles, applications, and security challenges of RFID systems. It then delves into ECC, which provides high-security strength with shorter keys, and RSA, which relies on large prime factorization and is widely used. Experimental results reveal that ECC offers advantages in encryption speed and key efficiency, especially in resource-constrained environments, while RSA remains suitable for specific scenarios. This study demonstrates the implementation of these algorithms in RFID systems and provides insights into their comparative strengths and constraints.
