Avalanche is similar to a landslide, but instead of land, the snow atop the mountains rapidly descends down. Just a little disturbance up top, could set a cycle that makes huge masses of snow to slide down. In cryptography, in the same way, if even tiny changes in the input key or plaintext occur, the ciphertext is changed drastically. Option A 0 votes 0 votes Please log in or register to add a comment.

If an input is changed moderately (for example, flipping a single bit), the output changes significantly. https://en.wikipedia.org/wiki/Avalanche_effect `JEET answered Jan 13, 2020 edited Jan 13, 2020 by `JEET `JEET comment Share Follow See all 4 Comments See all 4 4 Comments reply Tuhin Dutta commented Jan 13, 2020 reply Follow Share Why not option b)? 0 votes 0 votes Aman Juyal commented Jan 13, 2020 reply Follow Share @tuhin dutta only because of minimally word. 0 votes 0 votes `JEET commented Jan 13, 2020 reply Follow Share Yes minimally was keyword here. 0 votes 0 votes commenter commenter commented Jan 24, 2020 reply Follow Share In the case of high-quality block ciphers, such a small change in either the key or the plaintext should cause a drastic change in the ciphertext. source: wikipedia and "Cryptography and Network security" book by janaki. It is stated in other books as well. So I'm more inclined to option a. as it states minimally also. 0 votes 0 votes Please log in or register to add a comment.
1 votes 1 votes Avalanche effect is a desirable property of block ciphers and cryptographic hash functions. It states that if input changes even slightly the change in the output will be significant So answer is a) Pratyush Priyam Kuan answered Feb 14, 2020 Pratyush Priyam Kuan comment Share Follow See all 0 reply Please log in or register to add a comment.
