Subject: RE: [kmip] Fwd: KMIP Suite B Profile - Deprecated

That is basically my take on it too. No new math, just use the options with more bits. The big policy piece is that they repackaged the program with a new name. 

NSA is calling for Suite B to be transition in favor of Commericial National Security Algorithm Suite which is effectively minLoS 192. Odd way to say Deprecated- but I think that is the simplest way to discribe it.

 In Government/Policy wonk speak that is the first line of the introduction  that notes " NSA's announcement of changes from Suite B cryptography to CNSA Suite"  

I think the intent is to differentiate what was considered good: "Suite B" to what the new definition of good is: "CNSA" 

The key language is found on page 9

"For those partners and vendors that have not yet made the transition to Suite B algorithms, we recommend not making a significant expenditure to do so at this point but instead to prepare for the upcoming quantum resistant algorithm transition." 
.... which also notes that you can use ECDH and RSA (but its not preferred"

The impact currently points to your minLoS of 192 and dropping minLoS 128. That might make the profile easier? Only one level of security to concern ourselves with.

From a security policy perspective there is the point that policy is simplified as all classification levels will be required to use minLoS 192.

Suite B is not deprecated - it continues. There is a new initiative to provide a mechanism for quantum resistant algorithm and its handling.
That initiative has not yet provided any results as such in terms of recommendations (that I'm aware of) for new algorithms. 

This is made clear at https://www.iad.gov/iad/programs/iad-initiatives/cnsa-suite.cfm

What the advisory guidance from that group at https://www.iad.gov/iad/library/ia-guidance/ia-solutions-for-classified/algorithm-guidance/cnsa-suite-and-quantum-computing-faq.cfm is that for anyone currently using Suite B to work only with the TOP SECRET specification level rather than the SECRET specification level on the basis of current perceptions as to possible future quantum computing vulnerability of algorithms at smaller key sizes. 

Basically recommendations have moved from minLOS 128 to minLOS 192.

At least that is my understanding.

Dear Technical Committee,

As you may be aware, Suite B is deprecated and replace with the Commercial National Security Algorithm (CNSA) Suite. 

See:  https://www.iad.gov/iad/library/ia-guidance/ia-solutions-for-classified/algorithm-guidance/cnsa-suite-and-quantum-computing-faq.cfm

The basic information for this was released in July, 2015 (see CNSS Advisory Memorandum, Information Assurance 02-15, July 2015 at https://www.cnss.gov/CNSS/issuances/Memoranda.cfm)

As such, several of the Key Lengths mentioned in your Suite B profile are prohibited for National Security Systems(see page 3 of the FAQ PDF). 

I am writing you to determine when a CNSA profile for KMIP 1.2 will be publicly available.

I look forward to your response,

Robert Wagner
