Threat model

regaudit-fhe operates inside a standard CKKS threat model:

  • The audit operator (the entity running the primitives) is honest but curious. Encrypted inputs are never decrypted server-side.
  • Auditor-public quantities are the regulation citations, the audit envelope schema, and a set of public group-cardinality scalars documented in each primitive's specification under docs/specs/.
  • IND-CPA security at 128 bits is inherited from the underlying CKKS parameter set (N = 2^15, log Q ~ 240, hybrid key switching dnum = 3).

Findings outside that model — for example, side-channel timing on the audit operator's host — should be reported through the same channel.
