ABSTRACT
Rapid development of multimedia technologies, research on safety and security are becoming more important. With this development, the number of user that used Web Server increase. Then the data keep changes. Because of that we need replication for the availability of data. Data replication is an important technique in peer to peer network, data grid architecture, clustering and distributed system. Data replication increases data availability and enhances data access and reliability and minimizes the cost of the data transmission. Web server consists of a set of nodes via a network. Each node contains a copy of the entire database. Queries can be submitted to any node in the cluster. Some of these queries may have problem. For example, if two concurrent transactions attempt to modify the same row of data, both updates cannot be applied simultaneously at one time. Beside that data that replicated from one database server to another database server not securely replicated. This paper proposed a secure data replication using encryption algorithm. This is method where data from a database will be encrypted first then replicate it to another server. Data encryption translates data into another form or code, so that only people with access to a secret key or password can read it. Primary purpose of applied this encryption is data will securely replicated over the network.

INTRODUCTION
Web server is a computer where the web content is stored. Basically web server is used to host the web sites but there exists other web servers also such as gaming, storage, FTP, email and etc. Web server working as respond to the client associated with the requested URL. Then it generating response by invoking a script and communicating with database. All the file or data that requested by client will automatically store in database storage.
Data replication is a process that copies and maintains database objects, such as tables in multiple databases. A change of the main database is reflected, forwarded and applied at each of the replicated server which might be in a remote location. Data replication can be drives by programs which transport data to some other location and then loaded at the receiving location. Primary purpose replication of data to increase the availability and faster server response time. Moreover, data replication need replicated in secure way to another database server.
Data encryption is the translation of data into a secret code. Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text encrypted data is referred to as cipher text
