Abstract :
Asynchronous transfer mode (ATM) users often open multiple ATM virtual circuits (VCs) to multiple ATM users on multiple ATM networks. Each network and user may implement a different encryption policy. Hence ATM users may need shared, flexible hardware-based encryption that supports multiple encryption algorithms for multiple concurrent ATM users and VCs. An algorithm-agile encryption architecture, that uses multiple, parallel encryption-pipelines, is proposed. The algorithm-agile encryptor´s effect on the ATM quality of service (QoS) metrics, such as cell transfer delay (CTD) and cell delay variation (CDV), is analyzed. Bounds on the maximum CDV and the CDV´s probability density are derived
