Question: 1 / 400

Which property indicates that a hash algorithm should distribute its resulting hash value uniformly throughout the output space?

Stability

Inversion

Security

Uniformity

The property that indicates a hash algorithm should distribute its resulting hash value uniformly throughout the output space is known as Uniformity. This means that for any given set of input data, the hash values produced should be spread evenly across the potential output range.

Uniform distribution is crucial because it minimizes the chances of collisions, where different inputs produce the same hash value. A uniform hash function will help ensure that when many different inputs are hashed, the outputs don’t cluster together in one region of the output space, which could lead to inefficiencies and risks in applications like data storage, retrieval, load balancing, or cryptographic security.

By achieving uniformity, a hash function enhances its effectiveness in various applications, including file integrity checks, password storage, and more, making it a vital characteristic in the design of hash algorithms.
