What are the main problems with private key cryptography?
What will be an ideal response?
Although enabling encryption in this way may be considered a simple solution, in reality it provides a weak degree of protection.This is primarily because of the problems associated with managing the keys. If the salesperson must download an encrypted file, then there must be a means for her to get the key to decrypt it. Sending the key in a separate e-mail message retrieved through the open hotspot would defeat the entire process. Even if she were to use her cell phone to call the office for the key, someone might hear the conversation or watch as she writes it down.Encrypting single documents using private key cryptography is a weak means of protection.
