Solution
The primary benefit of using public key cryptography over symmetric key cryptography is Simplified secure key management and distribution.
Here's why:
In symmetric key cryptography, the same key is used for both encryption and decryption. This means that the key must be shared between the sender and the receiver. If the key is intercepted during transmission, the security of the data is compromised. Therefore, secure key management and distribution can be complex and challenging.
On the other hand, public key cryptography uses two keys: a public key for encryption and a private key for decryption. The public key can be freely distributed because it is useless without the corresponding private key. This greatly simplifies secure key management and distribution, as the private key never needs to be transmitted or shared.
