“…For these 20 years, it has held up against cryptanalysis remarkably well and is still secure against all but possibly the most powerful adversaries. Because of its prevalence throughout the encryption market, DES [4] is an excellent interoperability standard between different encryption equipment. The predominant weakness of DES is its 56-bit key which, more than sufficient for the time period which it was developed [5], has become insufficient to protect against brute-force attacks modern computers [6].…”

Data Encryption Standard (DES) is based on the Feistel block cipher, developed in 1971 by IBM cryptography researcher Horst Feistel. DES uses 16 rounds of the Feistel structure. But with the changes in recent years, the internet is starting to be used more to connect devices to each other. These devices can range from powerful computing devices, such as desktop computers and tablets, to resource constrained devices, When it comes to these constrained devices, using a different key for each round cryptography algorithms fail to provide necessary security and performance.

“…Caesar cipher is one of the oldest ciphers, In Caesar cipher encryption [5], every letter is replaced by a letter that comes after the 'k' letters, in Caesar cipher decryption, every letter in the cipher text is replaced by a letter that comes 'k' letter before the cipher text letter. DES (Data Encryption Standard) [6], AES (Advanced Encryption Standard) [7], Blowfish [8], and RC4 [9] are a few examples of symmetric encryption algorithms.…”

This paper provides details on smart card authentication software. The software uses the smart card, smart card reader/writer device, NFC (Near Field Communication), data card printer, and web application. The data collected from the user through the web application will be stored in the smart card in encrypted format using a smart card writer during registration and also basic details of the user will be printed on the smart card using the data card printer. When the user produces the card for authentication the smart card reader, reads and decrypts the details stored in the smart card. Keywords: NFC, Data card printer, Encryption, Decryption, ACR122U, APDU.

“…They also identified the need for changing the symmetric key frequently sothat the data privacy of cloud data can be extended further [12]. Kefa Rabah [13] has analyzed Data Encryption Standard (DES) algorithm and its sustabinability in securing data. He has compared the performance of DES with that of the other symmetric key cryptsystems.…”

“…He has compared the performance of DES with that of the other symmetric key cryptsystems. He suggested that cryptographic algorithms must be carefully selected and implemented in order to have a strong cryptosystem that can maintain the secrecy of data in transit or at rest [13].…”

Cloud Computing is an excellent technology for Micro Medium and Small Enterprises, which operate under budget shortage for setting up their own Information Technology infrastructure that requires capital investment on resources such as computers, storage and networking devices. Now-a-days, major Cloud Providers like Google and Amazon provide cloud services to its customers for managing their email, contact list, calendar, documents, and their own websites. MSME can take advantage of the cloud-based solutions offered by various Cloud Service Providers for equipping their own employees in doing their day to day activities more effectively and on the cloud. Though cloud computing promotes less expensive and collaborative work environment among a group of employees, it involves risks in keeping the resources such as computing and data secured. Different mechanisms are available for securing the data on the cloud among which encryption of data using cryptographic algorithm is the widely used one. Among various encryption symmetric algorithms, Advanced Encryption Standard is the more secured symmetric encryption algorithm for implementing data privacy on the cloud. In this paper, the authors have discussed some of the issues involved in adopting the cloud in an organization and proposed solutions that will benefit an organization while uploading and managing data in files and databases on the cloud.
