A cipher suite is a set of algorithms that help secure a network connection. Suites typically use Transport Layer Security (TLS) or its deprecated predecessor Secure Socket Layer (SSL). The set of algorithms that cipher suites usually contain include: a key exchange algorithm , a bulk encryption algorithm , and a message authentication code ...
Both Suite A and Suite B can be used to protect foreign releasable information, US-Only information, and Sensitive Compartmented Information (SCI)." [1] In 2018, NSA replaced Suite B with the Commercial National Security Algorithm Suite (CNSA). [2] Suite B's components were: Advanced Encryption Standard (AES) with key sizes of 128 and 256 bits.
In August 2015, NSA announced that it is planning to transition "in the not distant future" to a new cipher suite that is resistant to quantum attacks. "Unfortunately, the growth of elliptic curve use has bumped up against the fact of continued progress in the research on quantum computing, necessitating a re-evaluation of our cryptographic ...
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 ...
Skipjack: the cipher developed for Clipper and finally published in 1998. Clipper chip : a controversial failure that convinced NSA that it was advisable to stay out of the public arena. Security-Enhanced Linux : not strictly a cipher device, but a recognition that in the 21st century, operating system improvements are more vital to information ...
Transport Layer Security pre-shared key ciphersuites (TLS-PSK) is a set of cryptographic protocols that provide secure communication based on pre-shared keys (PSKs). These pre-shared keys are symmetric keys shared in advance among the communicating parties.
Table compares implementations of block ciphers. Block ciphers are defined as being deterministic and operating on a set number of bits (termed a block) using a symmetric key. Each block cipher can be broken up into the possible key sizes and block cipher modes it can be run with.
A recently-discovered Internet-available procurement specifications document for the military's new key load device, the NGLD-M, reveals additional, more current, Suite A algorithm names and their uses (page 48, section 3.2.7.1 Algorithms): [2] ACCORDION 1.3 & 3.0 - TrKEK Encrypt/Decrypt and Internal Key Wrap, respectively.
