In an asymmetric cryptography system, what does the hashing activity primarily provide?

In an asymmetric cryptography system, the hashing activity primarily provides integrity. Hashing is a process that transforms data into a fixed-length string of characters, which serves as a unique identifier for the original data. When the hash is generated, any alteration to the original data, even a small change, will produce a completely different hash value. This quality allows users to verify that the data has not been altered during transmission or storage.

Integrity is crucial in information security because it ensures that the data remains accurate and trustworthy. By using hashes, receiving parties can check that the data they receive matches the original data sent, affirming that it has not been tampered with. Hashing does not encrypt the data itself, nor does it provide confidentiality, non-repudiation, or availability, which are related to other functions and aspects of cryptographic systems. Thus, the primary role of hashing in this context is to maintain the integrity of the data.
