The creation of a RFID/USN environment has increased rapidly due to the activation of ubiquitous security environment suitable for RFID/USN environment but has failed to comply with the speed of security threats. Therefore, this thesis presents MSNR suitable for RFID/USN. The MSNR presented showed an increase in the processing rate of 1.3 times compared to the existing AES and showed 2 fold improvement in performance in terms of the overall system efficiency. Therefore, MSNR is considered to be a password algorithm suitable to overcome the conditions of environmental resource conditions, such as RFID/USN.

Four varieties of tobacco, Nicotiana tabacum var. NC 2326. NC 95, NC 744 and Havana. and two plant species, Physalis floridana Rydb., N. repanda Wild. were used for classification of ten isolates of potato virus Y(PVY) obtained Iron potato or tabacco plants showing various symptoms. Each of the 10 isolates could be distinguished by the host reactions showing necrosis, vein banding and/or mottling, or no symptom on these hosts. Five isolates of PVY, PVY-VN, PVY-N, PVY-NSNR, PVY-Chile, and PVY-Argentina, showed necrotic symptom on NC 2326, but others showed vein handing and/or mottling symptom. On NC95, each of the isolates tested showed similar symptons as on NC2326, except necrotic symptom by the isolate PVY-MSNR. Havana showed mottling reaction to the PVY-NSNR, PVY-MSNR, PVY-MSMR, PVY-VB, and necrosis to PVY-Chile, PVY-Argentina, but showed no symptom to the others. NC744 showed mottling symptom to the PVY-MSNR and PVY-MSMR, necrosis to the PVY-Chile and PVY-Argentina, and no symptom to the others. On N. repanda, necrotic reaction to PVY-Argentina. no symptom to PVY-VN and PVY-C, and nettling to others were observed.
