Question 2.
What is the key advantage of the ElGamal scheme?
Show hintHide hint
Consider the method of 'masking' in the process.
3Question 3.
What is the main benefit of public key cryptography?
- It requires sharing a single key
- It allows secure key exchange without prior connection
- It encrypts data
Show hintHide hint
Think about how keys are exchanged.
4Question 4.
The security of ElGamal encryption relies on which of the following problems?
- Discrete Logarithm Problem
- Prime Factorization Problem
Show hintHide hint
Which one relates to the key exchange method used?
Question 5.
Consider a scenario where a public key system is employed in a bank for secure transactions. How might an attacker attempt to exploit weaknesses in such a system?
Show hintHide hint
Think about possible vulnerabilities in cryptographic systems.
