The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]), [5] is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. [6] AES is a variant of the Rijndael block cipher [5] developed by two Belgian ...

Advanced Encryption Standard (AES): an encryption algorithm, selected by NIST after a public competition. In 2003, NSA certified AES for Type 1 use in some NSA-approved systems. Secure Hash Algorithm: a widely used family of hash algorithms developed by NSA based on earlier designs by Ron Rivest. Digital Signature Algorithm; Data Encryption ...
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.
The most commonly used encryption cipher suit is AES, [73] as it has hardware acceleration for all x86 based processors that has AES-NI. A close contender is ChaCha20-Poly1305 , which is a stream cipher , however it is commonly used for mobile devices as they are ARM based which does not feature AES-NI instruction set extension.
The security of RSA relies on the practical difficulty of factoring the product of two large prime numbers, the "factoring problem". Breaking RSA encryption is known as the RSA problem. Whether it is as difficult as the factoring problem is an open question. [3] There are no published methods to defeat the system if a large enough key is used.
This allows for convenient comparison between algorithms and is useful when combining multiple primitives in a hybrid cryptosystem, so there is no clear weakest link. For example, AES-128 (key size 128 bits) is designed to offer a 128-bit security level, which is considered roughly equivalent to a RSA using 3072-bit key.
Encryption is used in the 21st century to protect digital data and information systems. As computing power increased over the years, encryption technology has only become more advanced and secure. However, this advancement in technology has also exposed a potential limitation of today's encryption methods.
