A government agency signs legal documents using RSA digital signatures. One day, they notice that different documents have identical digital signatures even though the contents are different. The RSA keypair is valid, and the documents were signed independently.
What is the most probable reason for this security failure?
a) The private key was compromised, allowing signature reuse. b) The same random value was used during the signature generation process. c) The hash function used before signing has collisions. d) The agency mistakenly encrypted the documents instead of signing them.
