The primary area of my research is Secure Cloud Computing over Outsourced Encrypted Data, where I develop advanced cryptographic techniques and protocols to preserve confidentiality, integrity, and privacy when encrypted data is delegated to third party cloud providers. I also investigate Blockchain Technology and Applications to strengthen transparency, auditability, and accountability in cloud services through the integration of blockchain mechanisms into secure cloud computing frameworks.

I have increased my focused on Post-Quantum Cryptography, especially Lattice-Based Cryptography, with the objective of designing quantum resilient constructions that secure modern cryptographic systems against emerging quantum adversaries. In parallel, I am exploring Quantum Cryptography, including quantum key distribution and quantum secure communication protocols, to contribute to next generation infrastructures capable of withstanding both classical and quantum threats.
