After 30 years of public scrutiny, nobody suspects DSA of having a backdoor. A paper by Neal Koblitz and Alfred Menezes discussed six different theories that were proposed to explain the timing of the announcment and the changes in the approved list of algorithms. This JEP does not propose to implement this protocol guidance.

NSA’s FAQs Demystify the Demise of Suite B, but Fail to Explain One Important Detail

Government and specified in NIST standards or recommendations. The retreat from requiring exclusive use of NIST elliptic curves for public key cryptography is explained by a desire to save money: A Cnsep signature requires less computation than an RSA signature with a full-size private exponent, and less computation means more battery life in mobile devices.

The FAQs make three points to explain the timing of the announcements: Goals Provide default implementations of the Suite B cryptographic algorithms in the JDK so that Java applications can meet appropriate security standards required by the U.

More information is available here. Suite B was announced on 16 February One of the questions in the FAQs document first question on page 10 confirms that the CNSA Suite does intend to retreat from the forward cnnssp requirement. Add oids for the supported algorithms.

Both the resistance to the adoption of ECC and the shift to other elliptic curves can be explained at least cnswp part by the Snowden revelations, and in particular by the confirmation of the backdoor in the Dual Elliptic Curve DRBG.


Government and specified in NIST standards and recommendations. Suite A will be used in applications where Suite B may not be appropriate. Historically, DSA has not been popular for several reasons. Please help to improve this article by cnssl more precise citations. Government — Version 1. Please improve this by adding secondary or tertiary sources.

Protocol profiles will be developed to aid in the selection of options to promote interoperability.

NSA Suite B Cryptography

Apply Clear All Save Filters. A key aspect of Suite B Cryptography is its use of elliptic curve technology instead of classic public key technology. And cryptographic random bit generators are becoming available to developers in all computing environments. David 11 February Need to update the list of supported crypto algorithms for export control paperwork.

This article has multiple issues. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations.

Support ccnssp thepair isn’t included in this effort, but can be added later if the need arises. I am looking for: Ensure that the implementations in our various crypto providers are interoperable; e. But the standardization process announced in the NIST report on post-quantum cryptography will take time.

Also, for EC related algorithms, we need to make sure that the required curves and parameters are supported. What is Suite B Cryptography.

Suite A will be used for the protection of some categories of especially sensitive information. This abrupt change of course, following many years of promoting ECC, took the cryptographic community fnssp surprise.

The Information Assurance Directorate at the NSA

However, as of AugustNSA indicated that only the Top Secret algorithm strengths ccnssp be used to protect all levels of classified information. This comes at the wrong time, now that most of the drawbacks of DSA are going away:.


Views Read Edit View history. Another suite of NSA cryptography, Suite A, contains some classified algorithms that will not be released. The announcements themselves provided some explanations, and the FAQs cndsp do a more thorough job, failing only to explain the omission of DSA.

If DSA is not being used, nothing is disrupted by dropping it. It was specified by NSA, and there were concerns that it might have a backdoor.

I suppose it was omitted simply because it is not being used, and no explanation was provided because nobody asked for one. This page was last edited on 12 Decemberat This article needs to be updated.

Following the NSA’s guidance on the protocol level would be a separate effort.

For additional information on these products, please click here For additional information on Suite B, please visit the link below: The implementation of CIS will facilitate the development of a broader range of secure cryptographic products which will be available to a wide customer base.

It is to serve as an interoperable cryptographic base for both unclassified information and most classified information. Please update this article to reflect recent events or newly available information. A bit modulus provides a security strength of bits for RSA and DH, while a bit modulus provides a security strength of bits. Description A Cryptographic Interoperability Strategy CIS was developed to find ways to increase assured rapid sharing of information both within the U.

At the crypto provider level, the only implementations missing that need to be supported are:
