Challenge Problems
Push your limits with advanced challenges
You are given a public key that we know is derived from a specific secret key. How might an attacker use this information to pose a threat, and what are the limits of their success?
💡 Hint: Consider the implications of knowing the public key versus the private key.
Explain how ElGamal could be attacked if the discrete logarithm problem were solved efficiently. What would be the implications for secure communications?
💡 Hint: Think about the relationship between the strength of the problem and its impact on cryptographic processes.
