An authentication server in Java implementation of an encryption framework model and DES algorithm in Java

The present work presents a framework model for communication channel encryption with functions similar to JCE (Java cryptography extensions) of Java, which allows any encryption algorithm to be codified and used in a simple and standard way. Through this proposed framework model, it is possible to insert cryptography in a transparent way in communication channels like conventional TCP/IP sockets. Using the proposal model, an authentication server was implemented, along with the encryption algorithm DES. The results obtained through the proposed framework show that the transparency obtained makes the development of applications using communication encryption simpler and standardized, besides decreasing the occurrence of programming errors. The authentication server implemented through the proposed framework model is used by information storage systems from CEFET-PR to ensure data transmission through the Internet. The language used was Java, because of its interoperability and portability
