and it soon became the default encryption algorithm ..

In this paper, the popular secret keyalgorithms including DES, 3DES, AES (Rijndael), Blowfish, were implemented, andtheir performance was compared by encrypting input files of varying contents andsizes. The algorithms were implemented in a uniform language (Java), using theirstandard specifications, and were tested on two different hardware platforms, tocompare their performance.

The Encryption and the Decryption algorithms are executed by senders and recipients respectively.

By considering different sizes of data blocks (0.5MB to 20MB)the algorithms were evaluated in terms of the time required to encrypt anddecrypt the data block. All the implementations were exact to make sure that theresults will be relatively fair and accurate.

This allows dynamic circuit specialization based on a specic key and mode (encrypt or decrypt).

Outgoing packets are labelled with the SA SPI ('the how') which the kernel used for encryption and authentication so the remote can lookup the corresponding verification and decryption instruction.

To solve these isses, IPSEC provides Internet Key Exchange to automatically exchange randomly generated keys which are transmitted using asymmetric encryption technology, according to negotiated algorithm details.

The decryption also has a login and password based on decryption algorithm and genetic algorithm.

In cryptography DES algorithm is used to encrypt a message and part of the message is hidden in 2DDCT of an image and the rest of the message will generate two secrete keys for the generation if high security.

This paper tries to present a fair comparison between themost common and used algorithms in the data encryption field. Since our mainconcern here is the performance of these algorithms under different settings,the presented comparison takes into consideration the behavior and theperformance of the algorithm when different data loads are used.

data encryption and decryption 2016 IEEE PAPER

Cipher text-Policy Attribute-based Encryption (CP-ABE) is considered as one of the most suitable scheme for data access control in cloud storage. Despite that the existing Outsourced ABE solutions are able to offload some intensive computing tasks to a third party, the verifiability of results returned from the third party has yet to be addressed. Aiming at tackling the challenge above, a new Secure Outsourced ABE system is proposed, which supports both secure outsourced key-issuing and decryption. This new method offloads all access policy and attribute related operations in the key-issuing process or decryption to a Key Generation Service Provider (KGSP) and a Decryption Service Provider (DSP), respectively, leaving only a constant number of simple operations for the attribute authority and eligible users to perform locally. In addition, for the first time, an outsourced ABE construction is proposed which provides checkability of the outsourced computation results in an efficient way.

As defined in RFC 2828 , cryptographic system is "a set of cryptographic algorithmstogether with the key management processes that support use of the algorithms insome application context." This definition defines the whole mechanism thatprovides the necessary level of security comprised of network protocols and dataencryption algorithms.
