Performance characteristics of Itanium/sup TM/ processor on data encryption algorithms

In this paper, performance characteristics of the Itanium/sup TM/ processor, the first implementation of the Itanium/sup TM/ Processor Family (IPF), is examined for the task of data encryption using public key and symmetric key encryption algorithms. The Itanium/sup TM/ processor key performance characteristics: wide issue width, large number of functional units, and large number of registers are examined for the task of performing multi-precision arithmetic dominant in public key algorithms and the computing requirements of symmetric key encryption algorithms.
