SUMMARY: On June 6, 1995, notice was published in the Federal Register
(60 FR 29830-29832) that a Federal Information Processing Standard for
Public Key Cryptographic Entity Authentication mechanisms was being
proposed for Federal use.
The written comments submitted by interested parties and other
material available to the Department relevant to this standard were
reviewed by NIST. On the basis of this review, NIST recommended that
the Secretary approve the standard as a Federal Information Processing
Standards Publication, and prepared a detailed justification document
for the Secretary's review in support of that recommendation.
The detailed justification document which was presented to the
Secretary, and which includes an analysis of the written comments
received, is part of the public record and is available for inspection
and copying in the Department's Central Reference and Records
Inspection Facility, Room 6020, Herbert C. Hoover Building, 14th Street
between Pennsylvania and Constitution Avenues, NW, Washington, DC
20230.
This FIPS contains two sections: (1) an announcement section which
provides information concerning the applicability, implementation, and
maintenance of the standard; and (2) a specifications section, which
deals with the technical requirements of the standard. Only the
announcement section of the standard is provided in this notice.
EFFECTIVE DATE: This standard becomes effective April 6, 1997.
ADDRESSES: Interested parties may purchase copies of this standard,
including the technical specifications section, from the National

Announcing--Entity Authentication Using Public Key Cryptography
Federal Information Processing Standards (FIPS PUBS) are issued
by the National Institute of Standards and Technology (NIST) after
approval by the Secretary of Commerce pursuant to Section 111(d) of
the Federal Property and Administrative Services Act of 1949 as
amended by the Computer Security Act of 1987, Public Law 100-235.
1. Name of Standard. Entity Authentication Using Public Key
Cryptography (FIPS PUB 196).
2. Category of Standard. Computer Security, Subcategory Access
Control.
3. Explanation. This standard specifies two challenge-response
protocols by which entities in a computer system may authenticate
their identities to one another. These protocols may be used during
session initiation, and at any other time that entity authentication
is necessary. Depending on which protocol is implemented, either one
or both entities involved may be authenticated. The defined
protocols are derived from an international standard for entity
authentication based on public key cryptography, which uses digital
signatures and random number challenges.
Authentication based on public key cryptography has an advantage
over many other authentication schemes because no secret information
has to be shared by the entities involved in the exchange. A user
(claimant) attempting to authenticate oneself must use a private key
to digitally sign a random number challenge issued by the verifying
entity. This random number is a time variant parameter which is
unique to the authentication exchange. If the verifier can
successfully verify the signed response using the claimant's public
key, then the claimant has been successfully authenticated.
4. Approving Authority. Secretary of Commerce.
5. Maintenance Agency. Department of Commerce, National
Institute of Standards and Technology, Computer Systems Laboratory.

Other NIST publications maybe applicable to the implementation
and use of this standard. A list (NIST Publications List 91) of
currently available computer security publications, including
ordering information, can be obtained from NIST.
7. Applicability. This standard is applicable to all Federal
departments and agencies that use pubic key based authentication
systems to protect unclassified information within computer and
digital telecommunications systems that are not subject to Section
2315 of Title 10, U.S. Code, or Section 3502(2) of Title 44, U.S.
Code. This standard shall be used by all Federal departments and
agencies in designing, acquiring and implementing public key based,
challenge-response authentication systems at the application layer
within computer and digital telecommunications systems. This
includes all systems that Federal departments and agencies operate
or that are operated for them under contact. In addition, this
standard may be used at other layers within computer and digital
telecommunications systems.
This standard may be adopted and used by non-Federal Government
organizations. Such use is encouraged when it is either cost
effective or provides interoperability for commercial and private
organizations.
8. Applications. Numerous applications can benefit from the
incorporation of entity authentication based on public key
cryptography, when the implementation of such technology is
considered cost-effective. Networking applications that require
remote login will be able to authenticate clients who have not
previously registered with the host, since secret material (e.g., a
password) does not have to be exchanged beforehand. Also, point-to-
point authentication can take place between users who are unknown to
one another. The authentication protocols in this standard may be
used in conjunction with other pubic key-based systems (e.g., a
public key infrastructure that uses public key certificates) to
enhance the security of a computer system.
9. Specifications. Federal Information Processing Standard
(FIPS) 196, Entity Authentication Using Public Key Cryptography
(affixed).
10. Implementations. The authentication protocols described in
this standard may be implemented in software, firmware, hardware, or
any combination thereof.
11. Export Control. Implementations of this standard are subject
to Federal Government export controls as specified in Title 15, Code
of Federal Regulations, Parts 768 through 799. Exporters are advised
to contact the Department of Commerce, Bureau of Export
Administration, for more information.
12. Implementation Schedule. This standard becomes effective
April 6, 1997.
13. Qualifications. The authentication technology described in
this standard is based upon information provided by sources within
the Federal Government and private industry. Authentication systems
are designed to protect against adversaries (e.g., hackers,
organized crime, economic competitors) mounting cost-effective
attacks on unclassified government or commercial data. The primary
goal in designing an effective security system is to make the cost
of any attack greater than the possible payoff.
While specifications in this standard are intended to maintain
the security of an authentication protocol, conformance to this
standard does not guarantee that a particular implementation is
secure. It is the responsibility of the manufacturer to build the
implementation of an authentication protocol in a secure manner.
This standard will be reviewed every five years in order to assess
its adequacy.
14. Waivers. Under certain exceptional circumstances, the heads
of Federal departments and agencies may approve waivers to Federal
Information Processing Standards (FIPS). The head of such agency may
re-delegate such authority only to a senior official designated
pursuant to section 3506(b) of Title 44, U.S. Code. Waivers shall be
granted only when:
a. Compliance with a standard would adversely affect the
accomplishment of the mission of an operator of a Federal computer
system, or
b. Cause a major adverse financial impact on the operator which
is not offset by Government-wide savings.
Agency heads may act upon a written waiver request containing
the information detailed above. Agency heads may also act without a
written waiver request when they determine that conditions for
meeting the standard cannot be met. Agency heads may approve waivers
only by a written decision which explains the basis on which the
agency head made the required finding(s). A copy of each such
decision, with procurement sensitive classified portions clearly
identified, shall be sent to: National Institute of Standards and
Technology, ATTN: FIPS Waiver Decisions, Building 820, Room 509,
Gaithersburg, MD 20899.
In addition, notice of each waiver granted and each delegation
of authority to approve waivers shall be sent promptly to the
Committee on Government Operations of the House of Representatives
and the Committee on Governmental Affairs of the Senate and shall be
published promptly in the Federal Register.
When the determination on a waiver applies to the procurement of
equipment and/or services, a notice of the waiver determination must
be published in the Commerce Business Daily as a part of the notice
of solicitation for offers of an acquisition or, if the waiver
determination is made after that notice is published, by amendment
to such notice.
A copy of the waiver, any supporting documents, the document
approving the waiver and any supporting and accompanying documents,
with such deletions as the agency is authorized and decides to make
under 5 U.S.C. Section 552(b), shall be part of the procurement
documentation and retained by the agency.
15. Where to Obtain Copies. Copies of this publication are
available for sale by the National Technical Information Service,
U.S. Department of Commerce, Springfield, VA 22161. When ordering,
refer to Federal Information Processing Standards Publication 196
(FIPS PUB 196), and identify the title. When microfiche is desired,
this should be specified. Payment may be made by check, money order,
credit card, or deposit account.
