Question

Introduction to network security and symmetric encryption

Answer 1

Symmetric and public key algorithms In symmetric key algorithms, the encryption and decryption keys are known both to sender and receiver. The encryption key is shared and the decryption key is easily calculated from it. In many cases, the encryption and decryption keys are the same.

Answer 2

Answer:

heya..

Network Security. Some people who cause security problems and why. The encryption model (for a symmetric-key cipher). The use of a one-time pad for encryption and the possibility of getting any possible plaintext from the ciphertext by the use of some other pad.
