Abstract

The development of computer systems and their interconnection via Internet has increased the dependence of both individuals and organizations. The Internet is a public network whose existence is very necessary as an information and communication medium, which is free. This, in turn, has led to a heightened awareness of security issues. Security problem are importaint. At information system many issues about computer crime and difficult to differend which true data. Many models which used to gain unauthorized access to data. In order for information to be used only by authorized people toavoid fraud and to ensure the security of users and server, a system needs to be developed whichseparates users and servers. One technology that can meet the requirement above is cryptography. In data, the needed assurances are that only intended recipients are able to access the appropriate information (confidentiality), that the information was not altered during transmission (integrity), thatthe information came from the appropriate sender (authentication).

Keywords: Security, cryptography, appropriate sender (authentication).
