二、Data Encryption Standard (DES) DES是一个运用Feistel Network来进行加密的流程,输入值的长度(block length)为64 bits, master key的长度为56 bits,一共进行16轮Feistel运算。因为是20世纪70年代提出来的加密标准,现在看来,56 bits的master key太短了,所以已经不再被推荐使用。

or NIST -- as an official Federal Information Processing Standard (FIPS) in 1977 for the encryption of commercial and sensitive yet unclassified government computer data.
The Data Encryption Standard (DES) [31] has been around for more than 25 years. During this time the standard was revised three times: as FIPS-46-1 in 1988, as FIPS-46-2 in 1993 and as FIPS-46-3 in 1999. DES was an outcome of a call for primitives in 1974, which did not res...
Data Encryption Standard In 1972, the NBS Institute for Computer Sciences and Technology (ICST) initiated a project in computer security, a subject then in its infancy.One of the first goals of the project was to develop a cryptographic algorithm standard that could be used to protect sensi-tiv...
Additionally, NIST (National Institute of Standards and Technology) has withdrawn DES as a standard. The DES algorithm can also be referred to as the Data Encryption Algorithm (DEA). DES Operational Overview At the high level, the DES algorithm takes a 56-bit key and applies it to the data...
VI.A.1. Data Encryption Standard The DES is an approach that uses complex procedures to encrypt the data and was developed by IBM in collaboration with the National Security Agency (NSA) and the NBS (now NIST) in the early 1970s. It was adopted as a standard in 1977 by the NIST for...
Advanced Encryption Standard (AES)-256, the National Institute of Standards and Technology (NIST) specification for a symmetric key data encryption that was adopted by the US government to replace Data Encryption Standard (DES) and RSA 2048 public key encryption technology.Feed...
The most important thing is to ensure that the tools you use to encrypt data meet today’s highest standards from the NIST and other regulatory security bodies. How Is Encryption Used? Encryption is used every day to protect a variety of data transactions online. You may not even realize som...
