Question

Which of the following statement is true for RSA algorithm ?

1.Security of RSA depends on problem of factoring large number

2.In software, RSA is 10 times slower than DES

3.In hardware, RSA is 100 times slower than DES

4.RSA can be faster than the symmetric algorithm


​

Answer 1

Security of RSA depends on problem of factoring large number

Explanation:

RSA algorithm is asymmetric cryptography algorithm

It Works on Public and private key

The idea of RSA is based on the fact that it is difficult to factorize a large integer.

It is widely used for secure data transmission

The acronym RSA comes from the surnames of Ron Rivest, Adi Shamir, and Leonard Adleman,

The security of RSA relies on the practical difficulty of factoring the product of two large prime numbers,

Security of RSA depends on problem of factoring large number  is Correct option .

2.In software, RSA is 10 times slower than DES Incorrect  (As In software, RSA is more than 100 times slower than DES)

3.In hardware, RSA is 100 times slower than DES  Incorrect  (As In hardware, RSA is more than 1000 times slower than DES)

4.RSA can be faster than the symmetric algorithm Incorrect ( As RSA is slower than symmetric algorithm .)

The security of RSA depends on problem of factoring large prime number

RSA is the modern public-key cryptosystem because of smaller keys, shorter signatures and better performance. It works with private and public keys and provide similar capabilities when compared to ECC
