NSA Suite A Cryptography
NSA Suite A Cryptography is NSA cryptography which "contains classified algorithms that will not be released." "Suite A will be used for the protection of some categories of especially sensitive information (a small percentage of the overall national security-related information assurance market)." Incomplete list of Suite A algorithms: * ACCORDION * BATON * CDL 1 * CDL 2 * FFC * Firefly (key exchange protocol), FIREFLY * JOSEKI * KEESEE * MAYFLY * MEDLEY * MERCATOR * SAVILLE * SHILLELAGH * WALBURN * WEASEL See also *Commercial National Security Algorithm Suite *NSA Suite B Cryptography References ;General NSA Suite B Cryptography / Cryptographic Interoperability Cryptography standards National Security Agency cryptography Standards of the United States {{US-gov-stub ...

NSA Cryptography
The vast majority of the National Security Agency's work on cryptography, encryption is classified information, classified, but from time to time NSA participates in standardization, standards processes or otherwise publishes information about its cryptographic algorithms. The NSA has categorized encryption items into four product types, and algorithms into two suites. The following is a brief and incomplete summary of public knowledge about NSA algorithms and protocols. Type 1 Product A Type 1 Product refers to an NSA endorsed classified or controlled cryptographic item for classified or sensitive U.S. government information, including cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed. Type 2 Product A Type 2 Product refers to an NSA endorsed unclassified cryptographic equipment, assemblies or components for sensitive but unclassified U.S ...

Firefly (key Exchange Protocol)
Firefly is a U.S. National Security Agency public-key key exchange protocol, used in EKMS, the STU-III STU-III (Secure Telephone Unit - third generation) is a family of secure telephones introduced in 1987 by the NSA for use by the United States government, its contractors, and its allies. STU-III desk units look much like typical office telephone ... secure telephone, and several other U.S. cryptographic systems.

SAVILLE
SAVILLE is a classified NSA Type 1 encryption algorithm, developed in the late 1960s, jointly by the Government Communications Headquarters (GCHQ) in the UK and the National Security Agency (NSA) in the US. It is used broadly, often for voice encryption, and implemented in many encryption devices. Little is known publicly about the algorithm itself due to its classified nature and inclusion in the NSA's Suite A. Some documentation related to the KYK-13 fill device and statements made by military officials confirm that SAVILLE has a 128-bit key, which consists of 120 key bits and an 8-bit checksum. Furthermore, it is known that SAVILLE has two modes of operation: Autonomous Mode (also known as Key-Auto-KEY or KAK) and Autoclave Mode (also known as Cipher-Text Auto Key or CTAK). On the AIM microchip, it runs at 4% of the clock rate (compare DES at 76% and BATON at 129%). The Cypris chip mentions two modes; specifications for Windster and Indictor specify that they provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial National Security Algorithm Suite
The Commercial National Security Algorithm Suite (CNSA) is a set of cryptographic algorithms 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 top secret level, while the NSA plans for a transition to quantum-resistant cryptography. The suite includes * 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 with a minimum modulus size of 3072. The CNSA transition is notable for moving RSA from a temporary ''legacy'' status, as it appeared in Suite B, to ''supported'' status. It also did not include the Digital Signature Algorithm The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for d ...

NSA Suite B Cryptography
NSA Suite B Cryptography was a set of cryptographic algorithms promulgated by the National Security Agency as part of its Cryptographic Modernization Program. It was to serve as an interoperable cryptographic base for both unclassified information and most classified information. Suite B was announced on 16 February 2005. A corresponding set of unpublished algorithms, Suite A, is "used in applications where Suite B may not be appropriate. Both Suite A and Suite B can be used to protect foreign releasable information, US-Only information, and Sensitive Compartmented Information (SCI)." In 2018, NSA replaced Suite B with the Commercial National Security Algorithm Suite (CNSA). Suite B's components were: * Advanced Encryption Standard (AES) with key sizes of 128 and 256 bits. For traffic flow, AES should be used with either the Counter Mode (CTR) for low bandwidth traffic or the Galois/Counter Mode (GCM) mode of operation for high bandwidth traffic (see Block cipher modes of ope ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
