Recent research in Ukraine discusses digital transformation of public services using distributed ledger technology (blockchain) . In these systems, "key transformation" is the process of generating public keys from private keys using elliptic curve cryptography, governed by specific state security "instructions". Typical Steps in a Key Transformation "Instruction"
Linking the new key to a specific user identity within a state or corporate registry. DIGITAL TECHNOLOGIES IN OPTIMIZATION OF THE ... - OUCI instruktsiia key transformation
It can refer to a Key Transformation Function (KTF) , where a master key or passphrase is mathematically modified (transformed) into a specific session key. In Eastern European regulatory standards (like DSTU), these "instructions" define exactly how bit-shifting and XOR operations must be performed to meet legal security requirements. DIGITAL TECHNOLOGIES IN OPTIMIZATION OF THE
Applying a cryptographic hash or a cipher-based transformation (e.g., using a salt or a specific constant). instruktsiia key transformation
Formatting the initial "raw" key according to specific padding rules.
Verifying the integrity of the transformed key using a checksum or digital signature.
In the context of the Ukrainian Ministry of Finance, "instruktsiia" often refers to the official procedural manuals for the Systema Logica AIS, which manages budget processes. A "key transformation" here would involve the technical process of re-encrypting or updating digital keys used for secure interbank payment operations.
