Question No. 02 [10 marks]
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 | 1024 to 4096 bits | asymmetric | RSA algorithm was proposed in 1978,1977 by Rivest, Shamir, and Adleman |
| AES | 128, 192, 256 bits | Symmetric | 1st published in 1998. Designers (Vincent Rijmen, Joan Daemen) |
| Serpent encryption algorithm | 128, 192, 256 bits | Symmetric | Serpent was designed by Ross Anderson, Eli Biham, and Lars Knudsen. |
