Securing information exchange over open network by changing layer two packet structure

Abstract EN

Exchanging sensitive data over computer networks requires high level of security to prevent intruders from acquiring that data.

Consequently, a robust methodology is required to protect that data from being violated.

In order to achieve that goal, this paper presents a Point-to-Point Protocol (PPP) level security mechanism that changes the structure of the exchanged packets, uses new protocol identifier and encapsulates MAC addresses in an encrypted form in the packet itself.
