tilbakekrypteringskoder

Tilbakekrypter is a Norwegian verb form that can refer to either the act of decrypting encrypted data or, in some contexts, the act of encrypting data again (re-encryption). The precise meaning depends on usage and is not standardized across technical literature; standard terms are dekryptering (decryption) and tilbakekryptering or re-encryption for re-encrypting.

In information security, re-encryption is used when data must be temporarily decrypted for processing and then encrypted again to preserve confidentiality, such as in secure data flows, cloud processing, or database encryption at rest with key management. The term may also arise in discussions about data in transit or data at rest, where different stages require different cryptographic states.

Important considerations include consent and legal authorization for accessing encrypted data, proper key management, and adherence to policy and regulation. While tilbakekrypter appears in Norwegian discussions, practitioners typically use established terms, and descriptions should specify the exact operation and keys involved. The term does not denote a single, universally defined cryptographic operation, and its interpretation depends on context, standards, and the specific encryption scheme in use.
