  2. NSA cryptography - Wikipedia

    en.wikipedia.org/wiki/NSA_Cryptography

    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.

  3. NSA encryption systems - Wikipedia

    en.wikipedia.org/wiki/NSA_encryption_systems

    The first commercial network layer encryption device was the Motorola Network Encryption System (NES). The system used the SP3 and KMP protocols defined by the NSA Secure Data Network System (SDNS) and were the direct precursors to IPsec. The NES was built in a three part architecture that used a small cryptographic security kernel to separate ...

    Advanced Encryption Standard (AES) Symmetric block cipher for information protection FIPS PUB 197: Use 256-bit keys for all classification levels. Module-Lattice-Based Key-Encapsulation Mechanism Standard (ML-KEM aka CRYSTALS-Kyber) Asymmetric algorithm for key establishment FIPS PUB 203: Use ML-KEM-1024 parameter set for all classification levels.

    en.wikipedia.org/wiki/ChaCha20-Poly1305

    ChaCha20-Poly1305 is an authenticated encryption with associated data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. [1] It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM .

    The LFSR is created by a 5-bit field. The constant bit operates on a key block once per round on the lowest bit in order to add non-key-dependent entropy to the key schedule. The LFSR has different logic for each sequence; however, the initial condition is the same for encryption. The initial condition of the LFSR for decryption varies on the ...

    The backdoor would allow NSA to decrypt for example SSL/TLS encryption which used Dual_EC_DRBG as a CSPRNG. [5] Members of the ANSI standard group to which Dual_EC_DRBG was first submitted were aware of the exact mechanism of the potential backdoor and how to disable it, [6] but did not elect to disable or publicize the backdoor.
