Question 5 • SC-Fundamentals of Computing - Content Recovery - Laws & Security

RSA encryption relies on _____. Select 4 options.

Answer
A
the use of prime numbers
B
a private key that only the server knows
C
a public key that the server and the user’s computer know
D
the system time
E
the difficulty in factoring large numbers

Explanation

RSA uses prime numbers to create its keys, and its security depends on how difficult it is to factor the product of large primes. It also uses a public key that can be shared with the user’s computer and a corresponding private key kept secret by the server. The system time is not a basis of RSA encryption.
