Securing and Compressing Transmission over LAN by using Public Key Cryptography

Gagandeep shahi, Charanjit singh

Local Area Network used everywhere. Plain message and long size of the message are the big problems for the LAN security. So to protect the authoritative data on LAN users has to apply the cryptography on one of these architectures. Cryptography the area of computer science which developed to provide security for the senders and receivers to transmit and receive confidential data through an insecure channel by a means of process called Encryption/ Decryption. Public key cryptography and Secret key Cryptography are types of cryptography. Public key cryptography provides the better security over the insecure computer networks. RSA and NTRU public key cryptography algorithms keep secrecy of private key between all users on the sensitive or insecure networks. Compression can be used with encryption to fast transmission over LAN. Simple String Compression Algorithm combine with NTRU and RSA & using Peer to peer approach can provide better security as well as short message size for fast transmission of the message over the LAN. Using peer to peer technique we can exclude the third party servers or central dependability which may be costly or may have poor security.
