FIPS PUB 186-4 . FEDERAL INFORMATION PROCESSING STANDARDS PUBLICATION . Digital Signature Standard (DSS) CATEGORY: COMPUTER SECURITY SUBCATEGORY: CRYPTOGRAPHY . Information Technology Laboratory . National Institute of Standards and Technology . Gaithersburg, MD 20899-8900. Issued July 2013 . U.S. Department of Commerc The Standard specifies a suite of algorithms that can be used to generate a digital signature. Digital signatures are used to detect unauthorized modifications to data and to authenticate the identity of the signatory. In addition, the recipient of signed data can use a digital signature as evidence in demonstrating to a third party that the signature was, in fact, generated by the claimed. This document, The FIPS 186-4 Digital Signature Algorithm Validation System (DSA2VS), specifies the procedures involved in validating implementations of the Digital Signature Algorithm as approved in FIPS 186-4, Digital Signature Standard (DSS) [1]. FIPS 186-4 FIPS 186-4 approves the use of implementations of either or both of these standards and specifies additional requirements. (3) The Elliptic Curve Digital Signature Algorithm (ECDSA) is specified in ANS X9.62. FIPS 186-4 approves the use of ECDSA and specifies additional requirements This standard supersedes FIPS 186-4. In the future, additional digital signature schemes may be specified and approved in FIPS publications or in NIST Special Publications

FIPS 140-2 itself doesn't say anything about DSS, though it has 186-2 as a reference. It was published in 2001, before 186-3 and -4, and has not been superseded. After 140-3 spent 8 years in draft they recently decided to consider using ISO/IEC 19790 instead! 140-2 Annex A (Approved functions) is updated frequently and does now reference 186-4 When using elliptic curve cryptography, a curve from FIPS 186-4 is used. Using Elliptic Curve Diffie-Hellman. When using a curve from FIPS 186-4, a base point order and key size of at least 224 bits for correctly implemented ECDH provides 112 bits of effective security strength. Security of a curve selected from another source cannot be assumed to have the same security using base point order and key size alone

Der DSS wurde zuerst in FIPS -PUB 186 veröffentlicht und zuletzt im FIPS-PUB 186-4 angepasst. Entworfen wurde er von der NSA im Rahmen des Versuchs der US-Regierung, hochsichere Verschlüsselung unter Kontrolle zu bringen NIST-recommended elliptic curves, previously specified in FIPS 186-4 Appendix D, are now included in Draft NIST Special Publication (SP) 800-186, Recommendations for Discrete Logarithm-Based Cryptography: Elliptic Curve Domain Parameters, which has a concurrent public comment period (ending January 29, 2020) The new SP800-131A and FIPS 186-4 restrictions on algorithms and key sizes complicate the use of ciphersuites for TLS considerably. This page is intended to answer the question can I configure an OpenSSL cipherstring for TLS to comply with the new FIPS restrictions?. This discussion assumes use of a FIPS capable OpenSSL 1.0.1f or later The value of SHA(M) is a 160-bit string output by the Secure Hash Algorithm specified in FIPS 180. For use in computing s, this string must be converted to an integer. The conversion rule is given in Appendix 2.2 FIPS 186-4 specifies three techniques for the generation and verification of digital signatures that can be used for the protection of data: the Rivest-Shamir-Adleman Algorithm (RSA), the Digital Signature Algorithm (DSA), and the Elliptic Curve Digital Signature Algorithm (ECDSA), along with a set of elliptic curves recommended for government use

However, the latest question involves FIPS 186-4 also (which refers more to the key generation/DSS itself). Any chance we have plans to support not just FIPS 140-2 certification (via WL8/SL) but also along with 186-4 certification (via same) through any of the crypto security blocks resident on the device(s)? Perhaps this can also be accomplished via a corresponding TI EP (Processor) with given crypto security blocks residing in silicon. FIPS 186-4 KeyGen - wolfSSL To support our customers pursuing FIPS 140-2 validations or Common Criteria evaluations, wolfSSL is adding FIPS 186-4 KeyGen to our next FIPS 140-2 validation. We are scheduled to complete CAVP algorithm testing in June and testing with our FIPS Laboratory in July compliance to FIPS 186-2 to modules tested and validated for compliance to FIPS 186-3 under the Cryptographic Module Validation Program.

FIPS PUB 186-4 - Digital Signature Standard (DSS

A: FIPS 186-4 was published years ago. CMVP declared an end-of-life for FIPS 186-2. Over 100 FIPS 140-2 modules with FIPS 186-2 algorithms were moved to the Historical List after the IG G.18 transition date of September 1, 2020. Q2: I am using one of the OpenSSL FIPS Object Modules (FIPS 140-2 Certs. 1747, 2398, 2473); what do I do The FIPS 186-4 standard specifies under Table B.1 that for a 1024 bit modulus, p1 and p2 must be greater than 100 bits. So that's fine. But for 2048 and 3072 bit modulii ( sp? ) the minimum bit length of p1 and p2 will not be met. Granted, ANSI X9.31 was written a long time ago, so maybe they didn't cover 2048 and 3072 bit numbers at the time RSA [FIPS 186-4] issue. We use the OpenSSL FIPS Object Module v.2.0, but are not allowed anymore (as of the start of this year) to submit new product for validation because the RSA implementation is only FIPS 186-2 compliant. Based on extensive review and research it seems to be possible to patch the RSA key generation to be FIPS 186-4. Digital signatures are used to detect unauthorized modifications to data and to authenticate the identity of the signatory. In addition, the recipient of signed data can use a digital signature as evidence in demonstrating to a third party that the signature was, in fact, generated by the claimed signatory Cleaner RSA and DSA key generation (largely based on FIPS 186-4) Major clean ups and simplification of the code base; PyCryptodome is not a wrapper to a separate C library like OpenSSL. To the largest possible extent, algorithms are implemented in pure Python. Only the pieces that are extremely critical to performance (e.g. block ciphers) are implemented as C extensions. For more information.

FIPS 186-4 approves the use of implementations of either or both of these standards and specifies additional requirements. (3) The Elliptic Curve Digital Signature Algorithm (ECDSA) is specified in ANS X9.62. FIPS 186-4 approves the use of ECDSA and specifies additional requirements. Recommended elliptic curves for Federal Government use are provided herein. This Standard includes requirements. FIPS 140-2 specifies conditions applicable to the environment of RSA (and other) key generation, and refers to FIPS 186-4 for the generation itself. Several recent Java Card Smart Cards can internally generate RSA-2048 key pairs per FIPS 186-4, with security policy and FIPS 140-2 level 3 certificate to attest that The Digital Signature Standard (DSS) is a Federal Information Processing Standard specifying a suite of algorithms that can be used to generate digital signatures established by the U.S. National Institute of Standards and Technology (NIST) in 1994. Four revisions to the initial specification have been released: FIPS 186-1 in 1996, FIPS 186-2 in 2000, FIPS 186-3 in 2009, and FIPS 186-4 in 2013

  1. Hi All, I am looking for the FIPS 186-4 patch. I see it is not yet implemented in openssl FIPS 2.0 I see many vendors have implemented their own fix for FIPS 186-4 compliance. I am looking for the patch which i can reuse. Looks like redhat too has its own patch. Kindly share any pointers for the (open license for reuse) patch for FIPS 186-4 compliance

What is the public-key format for ECDSA as in FIPS 186-4, and where is it formally defined? In particular, are there variants beyond Cartesian coordinates? Is that a pair of bitstrings, or a pair of integers, and with exactly what ASN.1 decoration (if any)? Would the point at infinity have a valid representation (I know it is not a valid public key)? I ask because I find various formats around. The algorithm closely follows NIST FIPS 186-4 in its sections B.3.1 and B.3.3. The modulus is the product of two non-strong probable primes. Each prime passes a suitable number of Miller-Rabin tests with random bases and a single Lucas test. Parameters: bits (integer) - Key length, or size (in bits) of the RSA modulus. It must be at least 1024, but 2048 is recommended. The FIPS standard only.
