4.5

Symmetrische Verschlüsselung

Animation 4.5-1 represents a symmetric-key encryption system with the encryption function E, the decryption function D and the secret key k. m means the message and c the ciphertext.

Encryption and Decryption are calculated by the following terms:

  • Encryption: c = E_k(m)

  • Decryption: m = D_k(c)
