Network infrastructure involves a variety of geographically distributed data sources, computational resources, storage systems, and databases and works as a unified integrated resource. Due to this security problems become an urgent and complex undertaking for the network applications. 512 bit RSA in today environment has become vulnerable to attacks and is considered no more secure. In order to secure data or information over a network we need to study different possible security issues in networks and to study how security issues affect the network performance. We will be investigating various solutions to these security issues and purpose an architectural based algorithm for providing security. We hereby will present an algorithm based on random alphanumeric string concatenation with addition to using n prime numbers. The idea behind this new technique is to provide maximum security for data by applying random alphanumeric string concatenation instead of ordinary integers over the network. Using combination of two different keys mechanism we will encrypt the plaintext twice. This will help to secure the data even if one succeeds to have an access to others private key Also we used n prime number which is not easily breakable and are difficult to decompose. This technique provides more efficiency, security and reliability over the networks.
