avainperustaisen

Avainperustainen is a Finnish adjective meaning based on a key. It is commonly used in information security, cryptography, and software and hardware documentation to describe methods, systems, or processes that rely on a cryptographic or access key rather than other credentials or mechanisms. In Finnish technical writing, avainperustainen can modify nouns such as salaus (encryption), todennus (authentication), or pääsyjärjestelmä (access system).

The term is formed from avain, meaning key, and perustainen or perusteinen, meaning based on or founded on. It is an attributive modifier and follows the usual Finnish grammar for adjectives, with inflection matching the noun it describes, for example avainperusteinen järjestelmä, avainperusteisen todennuksen, avainperusteisen pääsyn hallinta.

Typical usages include avainperusteinen salaus (key-based encryption), avainperusteinen todennus (key-based authentication), and avainperusteinen pääsyvalvonta (key-based access control). The phrase is applicable to both symmetric and asymmetric cryptographic keys and to non-cryptographic contexts where a primary key governs access or operation.

Notes and considerations: avainperustainen is a broad, somewhat generic descriptor. Without specification, it does not convey which type of key, which cryptographic scheme, or which protocol is used. For precise discussions, it is helpful to specify the key type (symmetric vs. asymmetric), the key management method, and the particular standards or algorithms involved.
