Last lecture, we discussed cryptographic protocols. In particular, we gave a quantum protocol for secret key exchange that is secure in an information theoretical sense provided there is a secure public classical channel. We also discussed bit commitment and showed that no quantum protocol has information theoretic security. Today we will discuss zero knowledge systems and give an example of a ...

this study was carried out to investigate the effect ofadministration of satureja khuzistanica essential oil (skeo) in drinking water on performance, lipid oxidation, activity of antioxidative enzymes and cholesterol content of thigh meat using 720 one-day-old ross 308 broiler chicks. the skeo was added into drinking water at zero (control-), 200, 300, 400 and 500 mg/l along with a treatment co...

in order to evaluate the effect of different levels of drought stress on some physiological parameters in grapevine, a potted experiment with iranian grapevine cultivars ‘sahani’, ‘bidane-sefid’ and ‘farkhii’ was conducted in summer of 2008. the experiment was performed while employing four drought stress (water potential of soil, ?s= -0.2, -0.6, -1, -1.5 mpa) treatments each in three replicati...
