<p>X3 C is a Swedish company which develops a world wide good tracking system by using ARFID </p><p>tags placed on every item which has to be delivered and base stations as gateway in a wireless </p><p>sensor network. The requirement of a long lifespan of their ARFID tags made it difficult to </p><p>implement security. Firstly an evaluation of possible security mechanisms and their power </p><p>consumption was done by measuring the avalanche effect and character frequency of the sym- </p><p>metric algorithms Blowfish, RC2 and XTEA. Secondly, the required CPU time which is needed </p><p>by each algorithm for encrypting a demo plaintext, was measured and analyzed. Summariz- </p><p>ing both analysis, the XTEA algorithm, run in CBC mode, is the recommendation for the XC </p><p>ARFID tags. The testing processes and the results are presented in detail in this thesis.</p>
