Source-derived summary

P-384 is the elliptic curve currently specified in Commercial National Security Algorithm Suite for the ECDSA and ECDH algorithms. It is a 384-bit curve over a finite field of prime order approximately 394×10113. Its binary representation has 384 bits, with a simple pattern. The curve is given by the equation y2 = x3 − 3x + b, where b is given by a certain 384-bit number. The curve has order less than the field size. The bit-length of a key is considered to be that of the order of the curve, which is also 384 bits.

Editorial summary

This brief starts where responsible research should: with the source description of “P-384” as elliptic curve used in cryptography. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 96-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where P-384, elliptic and curve can be independently traced.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as elliptic curve used in cryptography. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jan 11, 2026. The linked authority identifier is Q25106508. None of the 0 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
