Commercial National Security Algorithm Suite
The Commercial National Security Algorithm Suite (CNSA) is a set of cryptographic algorithms Promulgation, promulgated by the National Security Agency as a replacement for NSA Suite B Cryptography algorithms. It serves as the cryptographic base to protect US National Security Systems information up to the Classified information#Top_Secret_(TS), top secret level, while the NSA plans for a transition to quantum-resistant cryptography. The 1.0 suite included: * Advanced Encryption Standard with 256 bit keys * Elliptic-curve Diffie–Hellman and Elliptic Curve Digital Signature Algorithm with curve P-384 * SHA-2 with 384 bits, Diffie–Hellman key exchange with a minimum 3072-bit modulus, and * RSA (cryptosystem), RSA with a minimum modulus size of 3072. The CNSA transition is notable for moving RSA (cryptosystem), RSA from a temporary ''legacy'' status, as it appeared in Suite B, to ''supported'' status. It also did not include the Digital Signature Algorithm. This, and the overall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Promulgation
Promulgation is the formal proclamation or the declaration that a new statute, statutory or administrative law is enacted after its final Enactment of a bill, approval. In some jurisdiction (area), jurisdictions, this additional step is necessary before the law can take effect. After a new law is approved, it is announced to the public through the publication of government gazettes and/or on official government bulletins. National laws of extraordinary importance to the public may be announced by the head of state or head of government on a national broadcast. Local laws are usually announced in local newspapers and published in bulletins or compendium, compendia of municipal regulations. Jurisdiction-specific details Armenia Bills are enacted by the President of Armenia and published in the ''Hayastani Hanrapetutyun, Official Gazette of Armenia''. Belgium Statutes are promulgated by the King of the Belgians and published in the ''Belgian Official Journal''. Decrees and Ordin ...

Diffie–Hellman Key Exchange
Diffie–Hellman (DH) key exchangeSynonyms of Diffie–Hellman key exchange include: * Diffie–Hellman–Merkle key exchange * Diffie–Hellman key agreement * Diffie–Hellman key establishment * Diffie–Hellman key negotiation * Exponential key exchange * Diffie–Hellman protocol * Diffie–Hellman handshake is a mathematical method of securely generating a symmetric cryptographic key over a public channel and was one of the first public-key protocols as conceived by Ralph Merkle and named after Whitfield Diffie and Martin Hellman. DH is one of the earliest practical examples of public key exchange implemented within the field of cryptography. Published in 1976 by Diffie and Hellman, this is the earliest publicly known work that proposed the idea of a private key and a corresponding public key. Traditionally, secure encrypted communication between two parties required that they first exchange keys by some secure physical means, such as paper key lists transported by a tr ...

Cryptography Standards
There are a number of standards related to cryptography. Standard algorithms and protocols provide a focus for study; standards for popular applications attract a large amount of cryptanalysis. Encryption standards * Data Encryption Standard (DES, now obsolete) * Advanced Encryption Standard (AES) * RSA the original public key algorithm * OpenPGP Hash standards * MD5 128-bit (obsolete) * SHA-1 160-bit (obsolete) * SHA-2 available in 224, 256, 384, and 512-bit variants * HMAC keyed hash * PBKDF2 Key derivation function (RFC 2898) Digital signature standards * Digital Signature Standard (DSS), based on the Digital Signature Algorithm (DSA) * RSA * Elliptic Curve DSA Public-key infrastructure (PKI) standards * X.509 Public Key Certificates Wireless Standards * Wired Equivalent Privacy (WEP), severely flawed and superseded by WPA * Wi-Fi Protected Access (WPA) better than WEP, a 'pre-standard' partial version of 802.11i * 802.11i a.k.a. WPA2, uses AES and other improvements o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Extension, extend or extended may refer to: Mathematics Logic or set theory * Axiom of extensionality * Extensible cardinal * Extension (model theory) * Extension (proof theory) * Extension (predicate logic), the set of tuples of values that satisfy the predicate * Extension (semantics), the set of things to which a property applies * Extension (simplicial set) * Extension by definitions * Extensional definition, a definition that enumerates every individual a term applies to * Extensionality Other uses * Extension of a function, defined on a larger domain * Extension of a polyhedron, in geometry * Extension of a line segment (finite) into an infinite line (e.g., extended base) * Exterior algebra, Grassmann's theory of extension, in geometry * Field extension, in Galois theory * Group extension, in abstract algebra and homological algebra * Homotopy extension property, in topology * Kolmogorov extension theorem, in probability theory * Linear extension, in order theory * S ...
