Abstract
With the exponential growth in mobile banking usage, securing mobile transactions has become a critical challenge due to the increasing number of cyber-attacks targeting sensitive financial data. This manuscript explores the design and implementation of hybrid cryptographic algorithms that combine symmetric and asymmetric encryption techniques to enhance the security of mobile banking transactions. Hybrid cryptography leverages the efficiency of symmetric key algorithms and the secure key exchange features of asymmetric cryptography, ensuring confidentiality, integrity, and authentication simultaneously. The study reviews existing cryptographic approaches for mobile banking security, proposes a novel hybrid encryption model tailored for mobile banking environments, and evaluates its performance using experimental data. Results demonstrate that the hybrid approach balances security and computational efficiency, making it suitable for resource-constrained mobile devices. The paper concludes by emphasizing the importance of hybrid cryptography in protecting mobile banking transactions against evolving security threats.
Keywords: Hybrid cryptography, mobile banking security, symmetric encryption, asymmetric encryption, data confidentiality, key management, transaction authentication.
