Cryptographic Security Shaken: Attack on Fiat-Shamir Transformation

New research has challenged the long-held assumption of the random oracle model in cryptography. Researchers demonstrated a method to trick proof systems using the widely adopted Fiat-Shamir transformation, enabling them to certify false statements. This transformation is crucial in systems like blockchains for verifying computations from external servers, relying on the random oracle model's assumption. The research shows that even under this assumption, attacks are possible. This finding necessitates a re-evaluation of the random oracle model and its implications for numerous cryptographic applications, raising concerns about blockchain security and the potential for cryptocurrency theft.
