Securing communications over ATM networks

This paper presents a survey of existing solutions aiming to secure communications over ATM networks. Different solutions are analyzed and compared. Details are given about the security services offered, their placement within the ATM Protocol Reference Model, the mechanisms to negotiate security services and the techniques to provide synchronization and dynamic key change during user data exchange. Additionally, this paper proposes a new ATM security solution - the Solution For Frequent Communications (SFFC) - suitable to protect communications between ATM stations or companies that need to frequently communicate. An implementation outline is also presented.
