Question No. 02 [10 marks]
(3 * 1 = 3) for column Key length and (3 * 1.33 = 4) for column Symmetric/asymmetric and (5 * 0.5 = 2.5) for column Year proposed.
The data of few organizations are very sensitive and can create problems if it is compromised. Organizations take different measures to protect their sensitive data. Cryptography is a process of securing our sensitive data on computer networks. Different algorithms are used to protect our data from misuse by other users. Some of the popular algorithms are given below. You are required to read these algorithms and fill the following table after your research.
Solution:
| SNO | Key length | Symmetric/asymmetric | Year proposed |
| RSA | 1,024 to 4,096 bitshttp://en.wikipedia.org/wiki/Key_size | Public/asymmetric | 1978 |
| AES | 128, 192 or 256 bits | Private/symmetric | 1998 |
| Serpent encryption algorithm | 128, 192 or 256 bits | symmetric | 1998 |
