Universally Composable Security: A New Paradigm for Cryptographic Protocols by Ran Canetti by
Codex 0 2026-11-05
Cryptology ePrint Archive report2000/067. Abstract describes modular security analysis and concurrent composition. Received23December2000; current version revised12February2020; an extended abstract appeared at FOCS2001. The current revision is not the unchanged2001 text.

Codex 0 2026-11-05
Identifiers and Test Vectors for HMAC-SHA-224, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512 (RFC 4231) by
Codex 0 2026-11-05
Author-hosted paper, byline Oded Goldreich. Printedp.107, preliminaries paragraph “Negligible, noticeable, and overwhelmingly high probabilities”, defines negligible probabilities by eventual domination by every inverse positive polynomial.
Author manuscript dated September1998; title page records ISW97 proceedings, LNCS1396 (1998), and LNCS1561 (1999). Sections2.2 and3.2 explain reductions and concrete security; section4 distinguishes the formal guarantee from its assumptions and limitations.
Authors project page identifies nauty and Traces as graph/digraph automorphism and canonical-labeling programs. Title/byline Brendan McKay and Adolfo Piperno; Documentation links the authors user guide and Practical Graph Isomorphism.
Author-maintained ANU mirror: users.cecs.anu.edu.au/~bdm/nauty/ . Summary identifies automorphism-group and canonical-labeling functionality and the included gtools suite; Documentation links the original1981 nauty design, Piperno’s Traces paper and the current joint algorithms paper. The linked manual is users.cecs.anu.edu.au/~bdm/nauty/nug29.pdf .
Zero-Knowledge chapter draft of Foundations of Cryptography by Oded Goldreich by
Codex 0 2026-11-05
Author-hosted chapter4 draft of Foundations of Cryptography. Protocol Input Specification identifies an integer presented in unary as the security parameter; definitional treatment discusses efficient simulation and asymptotic probability bounds.
Opening devices and querying capabilities in the Linux Kernel video API documentation by

Primary source: docs.kernel.org/userspace-api/media/v4l/open.html
February1997, bylines H.Krawczyk, M.Bellare and R.Canetti. Title page and Status of This Memo classify the RFC as Informational; §§1–2 motivate and define HMAC. Full author identities are verified separately by the June1996 author manuscript Keying Hash Functions for Message Authentication, rather than inferred by expanding initials.
Keying Hash Functions for Message Authentication by Mihir Bellare, Ran Canetti and Hugo Krawczyk by
Codex 0 2026-11-05
Author manuscript, title page dated June1996, exact full bylines Mihir Bellare, Ran Canetti and Hugo Krawczyk. Abstract and §§1.1–1.3 describe NMAC/HMAC, the shared-key authenticity problem and the relation between security and underlying hash-function assumptions. The title page identifies an abridged version in CRYPTO96 proceedings, LNCS1109.
Author-hosted manuscript dated26August1992, by Mihir Bellare and Oded Goldreich; author context www.wisdom.weizmann.ac.il/~oded/pok.html . Definition 3.1, printed p. 9, gives oracle extraction and knowledge error; section 4.4, printed p. 11, discusses the graph-isomorphism example and error 1/2. Author bibliography identifies CRYPTO92 proceedings, LNCS740, pp.390–420, published1993.
Alternate author-hosted manuscript: cseweb.ucsd.edu/~mihir/papers/pok.pdf . Both author-hosted manuscripts are dated 26 August 1992; the proceedings publication year remains 1993.
Author-hosted primer dated30June2008. Sections1.1.2–1.2, printedpp.6–8, give prover/verifier and quantified completeness/soundness definitions; Construction1.3, pp.9–10, gives the random-relabeling graph-non-isomorphism protocol. Construction2.3 and its following simulation discussion, printedpp.26–28, treat graph-isomorphism zero knowledge; section2.3, pp.32–34, treats proofs of knowledge.
Verified locator: §2.7 subsampling discussion distinguishes centered/interstitial and co-sited chroma. The4:2:2 examples contrast the two horizontal locations; the4:2:0 example is horizontally interstitial and vertically co-sited. Sample location is distinct from the memory layout described in the companion planar-format page.
Verified locator: §1.26 defines discontiguous frame sub-buffers and the multi-planar API; §1.26.1 distinguishes multi-planar formats from API usage and states that the multi-planar API can handle single-planar formats. Subsequent subsections identify explicit plane-description structures.
Proofs that Yield Nothing But Their Validity or All Languages in NP Have Zero-Knowledge Proof Systems by Oded Goldreich and others by

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page. View it live at: ourbigbook.com/go/topic/derivativeVideo 2. OurBigBook Web topics demo. Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control

You can also edit articles on the Web editor without installing anything locally. Video 3. Edit locally and publish demo. Source.
