Impact of Configurability and Extensibility on IPSec Protocol Execution on Embedded Processors
- Security protocols, such as IPSec and SSL, are being increasingly deployed in the context of networked embedded systems. The resource-constrained nature of embedded systems and, in particular, the modest capabilities of embedded processors make it challenging to achieve satisfactory performance while executing security protocols. A promising approach for improving performance in embedded systems is to use application-specific instruction set processors that are designed based on configurable and extensible processors. In this work, we perform a comprehensive performance analysis of the IPSec protocol on a state-of-the-art configurable and extensible embedded processor (Xtensa from Tensilica, Inc.). We present performance profiles of a lightweight embedded IPSec implementation running on the Xtensa processor, and examine in detail the various factors that contribute to the processing latencies, including cryptographic and protocol processing. In order to improve the efficiency of IPSe...
