AI model Claude has cracked a long-standing cryptographic mystery involving NSA-provided numbers for NIST elliptic curves.
AI model Claude has cracked a long-standing cryptographic mystery involving NSA-provided numbers for NIST elliptic curves. JUST (JST) is trading at ₹12.9 ($0.1356). This is an original Token Times brief based on reporting by Cointribune, with live market data added, as of Sat, 17 Oct 2026 16:30:01 UTC.
This development highlights AI's growing capability to solve complex cryptographic problems, potentially impacting cryptographic standards and security practices. It also addresses longstanding concerns about potential backdoors in widely-used cryptographic algorithms.
- Claude AI solved a 25-year-old cryptographic puzzle in under 30 minutes.
- The puzzle involved numbers from NSA for NIST elliptic curves standardized in 2000.
- The numbers originated from a 1997-1998 pseudo-random generator, not a backdoor.
Anthropic's AI model Claude has made a significant breakthrough in cryptography by solving a 25-year-old puzzle involving numbers provided by the NSA for NIST elliptic curves. The AI was able to determine the origin of these numbers in under 30 minutes.
The numbers in question were part of elliptic curves standardized by NIST in 2000 and had been a subject of suspicion regarding potential backdoors. Claude's analysis revealed that the numbers were generated from an old pseudo-random generator fed by timestamps from 1997 and 1998.
This development showcases the increasing capability of AI in solving complex cryptographic problems, which could have far-reaching implications for the field. It also puts to rest longstanding concerns about the presence of backdoors in widely-used cryptographic standards.
The broader context of this event is the ongoing evolution of AI and its applications in various fields, including cryptography. As AI technology advances, its ability to tackle and solve complex problems is expected to grow, potentially transforming how cryptographic challenges are approached.
In the current market context, with the total crypto market cap at $2.8 trillion and 
Bitcoin experiencing a slight decline of 0.40% in the last 24 hours, this development may not have an immediate impact on market prices. However, it underscores the importance of robust cryptographic standards in the crypto space.
Since this brief published about 2 hours ago, JUST (JST) has moved from ₹12.88$0.1355 to ₹12.90$0.1356 — +0.10%.
The chart plots JST's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from Token Times's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 JST ≈ ₹14.37 (about $0.1356), down 1.0% over 24 hours. The rupee itself trades about 11.4% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.

Anthropic's Claude AI Solves 25-Year-Old NSA Cryptograph — questions & answers
What did Claude AI actually solve?
Claude AI solved the mystery of the origin of five numbers provided by the NSA for NIST elliptic curves, revealing they came from a 1997-1998 pseudo-random generator.
Why is this significant for cryptography?
This demonstrates AI's potential to solve complex cryptographic problems, impacting future security practices and standards.
Were the NSA numbers hiding a backdoor?
No, the analysis showed the numbers originated from a pseudo-random generator, not a backdoor.
How much is 1 JUST worth in rupee today?
About ₹14.37 at the live peer-to-peer (P2P) USDT rate, which is what Indians typically trade at — equivalent to roughly $0.1356. The rupee price moves with both JST's US-dollar price and the USDT/INR rate; use our JUST in rupee page for any amount.
Has JUST's price moved since this brief was published?
JST is up 0.10% since this brief first published — trading at ₹12.9 ($0.1356) now versus ₹12.88 ($0.1355) at publication. Token Times re-checks this figure against CoinGecko and Binance every 15 minutes.
