RFID Bi-Directional Authentication Protocol Based on Dynamic Coupled Integer Tent Map
Liu Jiandong,Zhang Xiao,Wang Yequan,Shang Kai 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.3
To meet the special needs of RFID, it is proposed to use a coupled dynamic integer tent map lattices model (DCML) to implement a Hash function and a random number generation scheme. The scheme is featured with fast operation. Based on this, this paper proposes RFID bi-directional authentication protocol. This has strictly proved by BAN logic. This protocol can resolve eavesdropping, illegal access, location tracking, impersonation and replay attack.

Endovascular Repair of Blunt Popliteal Arterial Injuries
Shan Zhong,Xiquan Zhang,Zhong Chen,Peng Dong,Yequan Sun,Wei Zhu,Xiaolin Pan,Deming Qi 대한영상의학회 2016 Korean Journal of Radiology Vol.17 No.5
Objective: To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. Materials and Methods: A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. Results: Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18–24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. Conclusion: Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair.
