Client Server communication overview in

POSNET system—Internet Mode

 

· POSNET system is a thin client server application.

· POSNET client application handles the user interface only.

· No data is being saved on the client’s machine.

· Client activity is being directly processed by the host server.

· All transactions between client and server, involve data transfer within the internet.

 

Technology description

We use both Rijndael (AES) symmetric algorithm and RSA public key

encryption technology,  in order to achieve maximum security in the data transfer.

 

· All the data that transfers between the client and the server is encrypted by the secret key.

· The process demonstrated above insures that only the client and the server know this secret key.

· Each time a client logs on and for every different client that logs on,
an individual and secure key is generated

Client

 

Server

1. Create public, private key using RSA

 

 

2. Send Public key to the server

 

3.  Generate secret key using  AES

 

 

4. Encrypt secret key with public key

6. Decrypt secret key with private key

 

5.  Send encrypted secret key to the client

7. Client and server has the same secret key.
