What is avalanche effect?

Avalanche Effect Avalanche effect means a small change in the plaintext (or key) should create a significant change in the ciphertext. DES has been proved to be strong with regard to this property. Avalanche Effect = (Number of Changed bit in ciphertext) / (Number of bits in ciphertext). A good cipher should always satisfy an avalanche > 50%.

What are the elements of an avalanche?

Terrain. Avalanches and avalanche paths share common elements: a start zone where the avalanche originates, a track along which the avalanche flows, and a runout zone where the avalanche comes to rest. The debris deposit is the accumulated mass of the avalanched snow once it has come to rest in the runout zone.

What is an avalanche in Italy?

A late winter avalanche in Gran Paradiso National Park, Valle d'Aosta, Italy. Avalanches are masses of snow, ice, and rocks that fall rapidly down a mountainside. They can be deadly. Falling masses of snow and ice, avalanches pose a threat to anyone on snowy mountainsides.

How do avalanche tracks work?

Once the avalanche starts to slide, it continues down the avalanche track, the natural path it follows downhill. After avalanches, large clearings or missing chutes of trees provide clues to an avalanche’s trajectory. The avalanche finally comes to a stop at the bottom of a slope, in the runout zone, where the snow and debris pile up.
