Vulnerabilities in Random Oracle Model Highlighted in New Study
/ 1 min read
🔍 Theoretical Cryptography Faces New Challenges with Random Oracle Model. A recent paper by Khovratovich, Rothblum, and Soukhanov highlights vulnerabilities in cryptographic protocols that rely on the random oracle model (ROM), which assumes hash functions behave like random functions. The authors demonstrate a contrived attack on zero-knowledge proving systems, raising concerns about the security of real-world applications, particularly in blockchain technology. As cryptographic schemes grow more complex, the risk of hidden backdoors increases, potentially compromising security across interconnected systems. The implications of these findings could reshape the understanding of cryptographic security, emphasizing the need for rigorous scrutiny of both theoretical models and practical implementations. Further exploration of these issues will continue in the upcoming second part of the discussion.
