Answer: Yes
Explanation:
Public key encryption is the encryption technique that is used for private keys and public keys for securing the system.Public key is used for encryption and private key is for decryption.Public keys can only open content of the system
- According to the question, public key encryption is secure for coffee shop customer payment process as they are stored on digital certificates in long form for verifying digital signature and encrypting information.Its computation is difficult to crack through power computer access.
- Other options is incorrect as encryption is not a problem for payment procedures. Thus, the correct option is yes ,public key encryption is secure method for coffee shop customers .
Explanation:
its an electronic device that processes data and stores information
DH is an algorithm to derive a shared secret over an unsafe channel.
Both parties exchange public keys, and can join them together with their private keys to create the secret. An eavesdropper can see both public keys, but since he doesn't posess the private keys, cannot derive the same secret.
The secret can be used to subsequently encrypt communications with a symmetric algorithm.
TLS uses this approach.
