Post-Quantum Cryptography Standardizationcite-ref-1[1] is a program and competition by NIST to update their standards to include post-quantum cryptography.cite-ref-2[2] It was announced at PQCrypto 2016.cite-ref-3[3] 23 signature schemes and 59 encryption/KEM schemes were submitted by the initial submission deadline at the end of 2017cite-ref-4[4] of which 69 total were deemed complete and proper and participated in the first round. Seven of these, of which 3 are signature schemes, advanced to the third round, which was announced on July 22, 2020.
On August 13, 2024, NIST released final versions of the first three Post Quantum Crypto Standards: FIPS 203, FIPS 204, and FIPS 205.cite-ref-nistrelase2024-5-0[5]

Background
Academic research on the potential impact of quantum computing dates back to at least 2001.cite-ref-6[6] A NIST published report from April 2016 cites experts that acknowledge the possibility of quantum technology to render the commonly used RSA algorithm insecure by 2030.cite-ref-7[7] As a result, a need to standardize quantum-secure cryptographic primitives was pursued. Since most symmetric primitives are relatively easy to modify in a way that makes them quantum resistant, efforts have focused on public-key cryptography, namely digital signatures and key encapsulation mechanisms. In December 2016 NIST initiated a standardization process by announcing a call for proposals.cite-ref-8[8]

Round two
Candidates moving on to the second round were announced on January 30, 2019. They are:cite-ref-33[33]

Round three
On July 22, 2020, NIST announced seven finalists ("first track"), as well as eight alternate algorithms ("second track"). The first track contains the algorithms which appear to have the most promise, and will be considered for standardization at the end of the third round. Algorithms in the second track could still become part of the standard, after the third round ends.cite-ref-2ndround-53-0[53] NIST expects some of the alternate candidates to be considered in a fourth round. NIST also suggests it may re-open the signature category for new schemes proposals in the future.cite-ref-54[54]
On June 7–9, 2021, NIST conducted the third PQC standardization conference, virtually.cite-ref-55[55] The conference included candidates' updates and discussions on implementations, on performances, and on security issues of the candidates. A small amount of focus was spent on intellectual property concerns.
Finalists
| Type | PKE/KEM | Signature |
|---|---|---|
| Lattice | CRYSTALS-Kyber NTRU SABER | CRYSTALS-Dilithium FALCON |
| Code-based | Classic McEliece | |
| Multivariate | | Rainbow |
Alternate candidates
| Type | PKE/KEM | Signature |
|---|---|---|

| Code-based | BIKE HQC | |
| Hash-based | | SPHINCS+ |
| Multivariate | | GeMSS |
| Supersingular elliptic curve isogeny | SIKE | |
| Zero-knowledge proofs | | Picnic |
Intellectual property concerns
After NIST's announcement regarding the finalists and the alternate candidates, various intellectual property concerns were voiced, notably surrounding lattice-based schemes such as Kyber and NewHope. NIST holds signed statements from submitting groups clearing any legal claims, but there is still a concern that third parties could raise claims. NIST claims that they will take such considerations into account while picking the winning algorithms.cite-ref-56[56]
Round three submissions published attacks
Adaptations
During this round, some candidates have shown to be vulnerable to some attack vectors. It forces these candidates to adapt accordingly:
CRYSTAL-Kyber and SABER
may change the nested hashes used in their proposals in order for their security claims to hold.cite-ref-58[58]
FALCON
side channel attack using electromagnetic measurements to extract the secret signing keys. A masking may be added in order to resist the attack. This adaptation affects performance and should be considered whilst standardizing.cite-ref-59[59]

First release
On August 13, 2024, NIST released final versions of its first three Post Quantum Crypto Standards.cite-ref-nistrelase2024-5-1[5] According to the release announcement:
While there have been no substantive changes made to the standards since the draft versions, NIST has changed the algorithms’ names to specify the versions that appear in the three finalized standards, which are: Federal Information Processing Standard (FIPS) 203, intended as the primary standard for general encryption. Among its advantages are comparatively small encryption keys that two parties can exchange easily, as well as its speed of operation. The standard is based on the CRYSTALS-Kyber algorithm, which has been renamed ML-KEM, short for Module-Lattice-Based Key-Encapsulation Mechanism. FIPS 204, intended as the primary standard for protecting digital signatures. The standard uses the CRYSTALS-Dilithium algorithm, which has been renamed ML-DSA, short for Module-Lattice-Based Digital Signature Algorithm. FIPS 205, also designed for digital signatures. The standard employs the SPHINCS+ algorithm, which has been renamed SLH-DSA, short for Stateless Hash-Based Digital Signature Algorithm. The standard is based on a different math approach than ML-DSA, and it is intended as a backup method in case ML-DSA proves vulnerable. Similarly, when the draft FIPS 206 standard built around FALCON is released, the algorithm will be dubbed FN-DSA, short for FFT (fast-Fourier transform) over NTRU-Lattice-Based Digital Signature Algorithm.
On March 11, 2025 NIST released Hamming Quasi-Cyclic (HQC) as the fifth algorithm for post-quantum asymmetric encryption as used for key encapsulation / exchange.cite-ref-nist250311-66-1[66] The new algorithm is as a backup for ML-KEM, the main algorithm for general encryption. HQC is a code-based scheme using different math than ML-KEM, thus mitigating possible weaknesses should any be found in the lattice-based ML-KEM.cite-ref-67[67] The draft standard incorporating the HQC algorithm is expected in early 2026 with the final in 2027.
