ADMINISTRATIVE RULES

Chapter 2885: Technical Standards for Digital Trust & Negative List Privacy

2885.0300 TOKENIZATION STANDARD

Algorithm: Argon2id (IETF RFC 9106)

Memory

64 MiB minimum

Time

2 passes minimum

Parallelism

2 threads minimum

Output

32 bytes (256 bits)

Token Construction

T = Argon2id(pass = Input Identifier, salt = Global Salt, secret = Authority Pepper)

Input Normalization

Uppercase, no whitespace, format as [Country]-[Subdivision]-[ID]

Example: "US-MN-D12345678"

2885.0400 LIFECYCLE MANAGEMENT

Pepper Rotation

Every 36 months minimum

List Regeneration

Within 24 hours of rotation

Version Control

Authorized Issuers must reject stale list versions (>24 hours)

This prevents bad actors from targeting issuers with outdated data during rotation windows.

2885.0500 PROHIBITION ON RAINBOW TABLES

PROHIBITED

Pre-computing hashes for entire populations is explicitly prohibited.

REQUIRED

Targeted hashing only—at time of transaction, for specific subject.

Privacy by Design

The Negative List architecture demonstrates that fraud prevention and privacy are not in tension:

  • No Raw Identifiers: The list stores only Argon2id tokens, not SSNs or license numbers
  • Authority Pepper: Stored in FIPS 140-3 Level 3 HSMs, rotates every 36 months
  • Version Control: Prevents replay attacks during rotation windows
