Q. Illustrate about RSA Encryption?
RSA Encryption
- Public key encryption technique
- Encryption steps:
- Encode data to be encrypted as a number to create the plaintext P
- Calculate the ciphertext C as C = PKp modulo N
(Divide PKp by N also keep only the remainder)
- Send C as the ciphertext
- Decryption steps:
- Receive C the ciphertext
- Calculate plaintext P = CKs modulo N
- Decode P to the original data
- Choosing Kp, Ks, and N
- Choose 2 prime numbers p and q (large # of digits - 200 or more)
- Calculate N = p * q
- Select Kp so that it is not a factor of (p -1)*(q -1)
- Select Ks so that (Kp * Ks) modulo (p - 1)*(q -1) = 1
Access Networks and Physical Media Access networks are the physical links(S) that connect an end systems to its edge router. Which is the first router on a path fr
Configure basic switch parameters. Configure the S1, S2, and S3 switches according to the following guidelines: Configure the switch hostname. Disable DNS lookup.
Simplicity The advantage of this approach is the simplicity of receiver buffering. The receiver need not buffer out of order packets the sender must maintain the upper an
While calculating shortest path, first we assume graph presentation of network at every node then we use Djikstra's algorithm to calculate shortest path from every node to other on
