The effect of algorithm-agile encryption on ATM quality of service
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 3encryption 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. That 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.
