...COMMUNICATION FOR SMALL AND MEDIUM ENTERPRISE USING CRYPTOGRAPHY ABSTRACT Information protection is one of the most important issues in every domain, especially when we are talking about enterprises. Information safety can be translated into three key terms: integrity, availability and data protection. There is a great number of means used in order to achieve the three objectives simultaneously. The most popular is cryptography because it offers a lot of techniques which nowadays are impossible to fail. In this paper we want to prove their efficiency by comparing the different types of crypto algorithms and by presenting their weaknesses and strengths. In order to maximize the benefits of the crypto techniques, we propose a hybrid approach that combines three crypto algorithms. INTRODUCTION Cryptography is a technique to scramble confidential information to make it "unreadable." It is commonly used in Internet communications to transmit data in secure way. Some potential problems during data communication on networking like unauthorized access, disclosure, interruption, use, modification, inspection, recording or destruction. The main ideas that security system has to respect are: confidentiality, data integrity, availability and authentication. These concepts characterize the data security achievement and must be accomplished by every secure communication that aims to be functional. Most security systems use cryptography because it offers various algorithms and techniques practically...

...transit between client and server and altering information on a web site. In all distributed environment electronic mail is the most heavily used network based application. It is the only application that is widely used across all architecture and vendor platforms. Users expect to be able to and do, send mail to others who are connected directly or indirectly to the internet. PGP(Pretty Good Privacy) is an open-source freely available software for E-Mail security. It provides authentication through the use of digital signature, confidentiality through the use of symmetric block encryption, compression using the ZIP algorithm, E-Mail compatibility using the radix-64 encoding scheme and segmentation and reassembly to accommodate long e-mails. Chapter 2 Review of literature tells the need and appraisal of e-mail security Software. E-mail is well established as a prime means of communication for business purposes that is quicker and cheaper than more traditional methods. Thus is necessary to make one’s corporate messaging system as secure as...

...substantiates the integrity of actual processing, such as balances on financial statements. The development of substantive tests is often dependent on the outcome of compliance tests. If compliance tests indicate that there are adequate internal controls, then substantive tests can be minimized. Stop-or-go sampling allows a test to be stopped as early as possible and is not appropriate for checking whether procedures have been followed. 2.

Since January 2002, the e-Business W@tch has analysed e-business developments and impacts in manufacturing, construction, financial and service sectors. All results are available on the internet and can be accessed or ordered via the Europa server or directly at the e-Business W@tch website (http://ec.europa.eu/comm/enterprise/ict/policy/watch/index.htm, www.ebusiness-watch.org). This document is a sector study by e-Business W@tch, focusing on the tourism industry. Its objective is to describe how companies in this industry use ICT for conducting business, to assess the impact of this development for firms and for the industry as a whole, and to indicate possible implications for policy. Analysis is based on literature, interviews, case studies and a survey among decision-makers in European enterprises from the tourism industry about the ICT use of their company.
