Comparison Chart BASIS FOR COMPARISON DES (DATA ENCRYPTION STANDARD) AES (ADVANCED ENCRYPTION STANDARD) Basic In DES the data block is divided into two halves. In AES the entire data block is processed as a single matrix. Principle DES work on Feistel Cipher structure. AES works on Substitution and Permutation Principle. Plaintext Plaintext is of 64 bits Plaintext can be of 128‚192‚ or 256 bits Key size DES in comparison to AES has smaller key size. AES has larger key size as

AES is a symmetrical encryption standard. The Advanced Encryption Standard‚ or AES is a specification for the encryption of electronic data established by the U.S. National Institute of standards and technology in 2001. It is based on the Rijndael cipher‚ and was developed by two Belgian cryptographers‚ Joan Daemen and Vincent Rijmen . AES is based in a design principlae known as a substitution-permutation network‚ and is fast both in software and hardware (Schneier). Unlike its predecessor DES‚

Considering digital image features with high volumes and video data‚ especially in real-time applications‚ the use of classic encryption methods like DES‚ AES‚ ...‚ is not efficient in terms of being time cosuming. In this article‚ a new method is proposed to encrypt digital images‚ using chos systems and utilizing DNA patterns. A central idea in the method suggested is to produce a pseudo-random DNA strand using chaos functions‚ which an encrypted strand is created‚ using the random strand and the

Before S/MIME‚ administrators used a widely accepted e-mail protocol to transfer messages‚ Simple Mail Transfer Protocol (SMTP)‚ which was inherently less secure. With S/MIME‚ administrators now have an e-mail option that helps provide greater security than SMTP‚ enabling widespread and secure e-mail connectivity. S/MIME provides two security services: •Digital signatures

1. Triple DES Triple DES was designed to replace the original Data Encryption Standard (DES) algorithm‚ which hackers eventually learned to defeat with relative ease. At one time‚ Triple DES was the recommended standard and the most widely used symmetric algorithm in the industry. Triple DES uses three individual keys with 56 bits each. The total key length adds up to 168 bits‚ but experts would argue that 112-bits in key strength is more like it. Despite slowly being phased out‚ Triple DES still

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 sensitive and valuable data during transmission and in storage. Prior to this NBS initiative‚ encryption had been largely the concern of military and intelligence organizations. The encryption algorithms‚ i.e.‚ the

The Enigma Code was a method of encryption created using the Enigma Machine to encrypt and information or messages. The Enigma machine was first invented by Arthur Scherbius at the end of world war I and was used commercially throughout the 1920s until it was adopted by multiple governments during WWII‚ including Germany‚ Japan‚ and Italy. This had allowed the Axis powers to safely and efficiently communicate sensitive information‚ but polish mathematician Marian Rejewski was able to break the code

Tricky Trouble on the Two Twins This quote was said by William H. Prescott in an attempt to save ammunition in the Battle of Bunker Hill. This battle was both fought on both Bunker and the nearby Breed’s Hill. The Battle of Bunker Hill had many advantages and disadvantages for both the British and the colonists in the geography. They used many weapons in the battle‚ close range‚ long range and sometimes even both. The battle was intense and action-packed as well as devastating and absolutely
