prime numbers only be used as encryption keys as in encryption the numbers are coded inj the form of 0s and 1s ,i.e binary form.

Which relies on prime numbers to generate keys?

Data encryption.


Why do you use large prime numbers?

Large primes numbers are used in public key encryption systems as when multiplied together to create an even larger composite number it is extremely difficult to factorise this number into its component primes - this is what gives the encryption its strength. It is the knowledge of the large prime factors of the even larger composite number which allows the encryption and decryption keys to be determined; they are dependent on each other and the prime factors.


What is public key encryption and why is it getting popular?

Public key encryption is the process of encoding messages in such a way that eavesdroppers or hackers cannot read the message but that authorized parties can. It uses two keys at the same time, a private key that is only known to your computer and a public key that your computer gives to another computer wanting to communicate with the former. Without both keys, the messages cannot be read. Both keys are based on prime numbers making this system extremely secure and popular because essentially there is an infinite number of prime numbers available, meaning a nearly infinite possibilities for keys.


How many keys are required for public key encryption?

two


What are prime numbers used for?

Modern encryption methods use prime numbers for keys. Prime numbers are used in multiple shops for seeking out the price of many objects, for example, if a load of 'KitKats' were being delivered, and the shop was a particular perfectionist and wanted the same amount of KitKats in every box, they would count them up, and if their total was a prime number, they would have a problem on their hand One big use in in coding information like credit card numbers on the computer so that they remain private. One of the first algorithms that did this was called RSA. The ones that are used now are much more sophisticated.


What kind of encryption uses the concept of public keys?

Asymmetric encryption employs the use of public/private key pairs.


Public key encryption is also known as asymmetric encryption?

Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.


Does asymmetric encryption involves keys?

Symmetric encryption requires one key known by both parties. Asymmetric encryption uses two keys, one encryption key known publicly and one decryption key known only by the recipient.Or more simply put,YesA public and private key
