Security engine targets high capacity wireless networks
As more multimedia enabled mobile devices continue to connect to networks in all market segments, it is estimated that there will be more than 50 billion connected devices in use by 2020. This rapid growth puts a lot of pressure on the wireless and wireline system infrastructure processing power and capabilities, and increases the need for robust security solutions.
As an example, 4G LTE-Advanced femtocells and base stations will be required to handle many more simultaneous data and voice channels than commonly used today. This will require data processing with increasingly aggressive performance and latency targets. Elliptic says its Multi-Packet Manager is specifically designed to address these challenges by significantly reducing the CPU and software loads and by improving the system level latencies via autonomous packet processing and automated key caching mechanisms.
The Multi-Packet Manager allows the host processor to dynamically add network packets to be processed while the security engine is busy processing data. Intelligent caching and pre-fetching reduces the bus traffic, internal buffering and power consumption without increasing the software load in a system. The engine is intended to reduce the CPU interrupt impact by allowing interrupts to be issued at the end of the packet list, after a specific number of packet descriptors have been processed, and on demand.
To meet the needs of multiple security applications such as 3GPP/LTE-Advanced, IPsec, SRTP, MACsec and storage, Elliptic’s Multi-Packet Manager security engine offers support for all required cipher and message authentication algorithms. This helps designers integrate security functions tuned for specific applications.
