An attacker forces a system to use a weaker encryption protocol that has known vulnerabilities. What type of cryptographic attack is being performed?
Side-channel attack
Downgrade attack
Birthday attack
Replay attack
By forcing a system to use a weaker encryption protocol with known vulnerabilities, an attacker is performing a downgrade attack. This attack leverages older, less secure versions of protocols or ciphers, making it easier to exploit the system. In contrast, a side-channel attack gathers information from the physical implementation of a cryptosystem, a birthday attack exploits the mathematics of hash functions to find collisions, and a replay attack involves reusing valid data transmissions to deceive a system or gain unauthorized access.
