An Efficient 2-Party Private Function Evaluation Protocol Based on Half Gates
Bingol, M.A.; Bicer, O.; Kiraz, Mehmet Sabir; Levi, A. (Article)Private function evaluation (PFE) is a special case of secure multi-party computation (MPC), where the function to be computed is known by only one party. PFE is useful in several real-life applications where an algorithm ... -
Efficient and Verifiable Algorithms for Secure Outsourcing of Cryptographic Computations
Kiraz, Mehmet Sabir; Uzunkol, Osmanbey (Article)Reducing computational cost of cryptographic computations for resource-constrained devices is an active research area. One of the practical solutions is to securely outsource the computations to an external and more powerful ... -
Security and Efficiency Analysis of the Hamming Distance Computation Protocol Based on Oblivious Transfer
Kiraz, Mehmet Sabir; Genc, Ziya Alper; Kardas, Suleyman (Article)Bringer et al. proposed two cryptographic protocols for the computation of Hamming distance. Their first scheme uses Oblivious Transfer and provides security in the semi-honest model. The other scheme uses Committed Oblivious ... -
Still Wrong Use of Pairings in Cryptography
Kiraz, Mehmet Sabir; Uzunkol, Osmanbey (Article)Several pairing-based cryptographic protocols are recently proposed with a wide variety of new novel applications including the ones in emerging technologies like cloud computing, internet of things (IoT), e-health ... -
THRIVE: threshold homomorphic encryption based secure and privacy preserving biometric verification system
Karabat, Cagatay; Kiraz, Mehmet Sabir; Erdogan, Hakan; Savas, Erkay (Article)In this paper, we introduce a new biometric verification and template protection system which we call THRIVE. The system includes novel enrollment and authentication protocols based on threshold homomorphic encryption where ...
