| Question 946 |
Avalanche effect in cryptography
| Is desirable property of the cryptographic algorithm | |
| Is undesirable property of the cryptographic algorithm | |
| Has no effect on the encryption algorithm | |
| None of the above |
Question 946 Explanation:
→ In cryptography, the avalanche effect is the desirable property of cryptographic algorithms, typically block cyphers and cryptographic hash functions, wherein if input is changed slightly (for example, flipping a single bit), the output changes significantly (e.g., half the output bits flip).
→ In the case of high-quality block cyphers, such a small change in either the key or the plaintext should cause a drastic change in the ciphertext.
→ In the case of high-quality block cyphers, such a small change in either the key or the plaintext should cause a drastic change in the ciphertext.
