Actual exam question for Eccouncil's 312-50 exam
Question #: 77
Topic #: 1
[All 312-50 Questions]

You are the lead cybersecurity analyst at a multinational corporation that uses a hybrid encryption system to secure inter-departmental communications. The system uses RSA encryption for key exchange and AES for data encryption, taking advantage of the strengths of both asymmetric and symmetric encryption. Each RSA key pair has a size of 'n' bits, with larger keys providing more security at the cost of slower performance. The

time complexity of generating an RSA key pair is O(n*2), and AES encryption has a time complexity of O(n). An attacker has developed a quantum algorithm with time complexity O((log n)*2) to crack RSA encryption. Given *n=4000' and variable 'AES key size', which scenario is likely to provide the best balance of security and

performance? which scenario would provide the best balance of security and performance?

Whoa, this quantum stuff is getting serious! I'm gonna need a bigger quantum computer to crack that RSA-4000 key.

I think option C, data encryption with AES-128, provides the best balance of security and performance.
