pbTLS Security Dimension On Embedded Devices

Project description

Already performed some early benchmarks: The test environment is a device-to-device scenario consisting of two ARM Cortex M4 @168 MHz and 20kByte RAM in combination with a WIZnet W5500 TCP/IP Ethernet controller. As a real life comparison we also captured performance data on a Windows or Linux based PC with Core i5 @1.7 GHz with 12GB RAM. Test application in all benchmarks is a normal (https) webserver demo. Baseline values for the PC: 50 ms for complete RSA key exchange and RSA key calculation at a total of ~200 ms for the complete transaction. The following devices are in our benchmark…
