What is the challenge that must be overcome with symmetric key cryptography?

  • choosing the encryption algorithm to ensure the secure transfer of the key
  • having the sender and receiver agree on the same secret key without anyone intercepting it
  • identifying the strength of the symmetric keys for implementation
  • selecting a central authority to manage the symmetric key

Explanation: With symmetric key encryption, the problem is getting the sender and receiver to agree on the same secret key without anyone else finding out. Because all keys in a secret-key cryptosystem must remain secret, the challenge has been with providing secure key management
