Abstract:
We formalize the notion of practical security of the encryption scheme introduced by C. Shannon as “the average amount of work to determine the key…” and define the corresponding practical security of key criterion. A comparison of the proposed criterion with the entropy criterion and the total variance criterion used in the quantum cryptography is given.
Key words:
models of key generation, key security, brute force attack optimization.
