Strengthening Cloud Security with ECSM-QKDP: A Quantum Key Distribution Protocol Approach

The research delivers an advanced version of Cloud Security Model defined as ECSM-QKDP which implements quantum cryptographic methods to protect cloud data. The proven quantum key distribution (QKD) method BB84 runs as an integral part in the model to perform secure key transfers between cloud entities. Data encryption through Hierarchical Attribute-Set Based Encryption (HASBE) delivers increased security and manages access control procedures. The implementation executes quantum cryptographic simulations through CloudSim Qiskit and iQuantum which operate in the cloud environment. The paper conducts experimental assessments to test ECSM-QKDP against AKE and PDP security protocols as well as other encryption models in the market. The results demonstrate key computation time decreases by 39.9% and encryption and decryption operations operate at 78% faster speed and cloud memory utilization reaches 55% better efficiency against standard security methods. The model ensures 99.8% secure cloud service delivery because it stands up well against quantum threats. The addition of distance bounding techniques in the developed Secure Authentication Protocol (SAP) enhances overall security features. ECSM-QKDP proves itself as a viable method to protect cloud-based data through efficient quantum security protocols which demonstrate scalability and quantum security.
