Optimised compact authentication scheme based on three factors for cloud-based electronic transactions

Key Points

• The aim is to develop a secure authentication scheme that uses three factors to enhance cloud transaction security.
• Developed a compact authentication scheme integrating three factors.
• Applied cryptographic techniques for secure data transmission.
• Tested the scheme in simulated cloud-based transaction scenarios.
• The new scheme showed a significant reduction in authentication time compared to existing methods.
• Enhanced security against common cyber threats was observed.
• User satisfaction improved due to the efficient authentication process.
