As Multiprotocol Label Switching (MPLS) is becoming a more widespread technology For providing virtual private network (VPN) services, MPLS architecture security is of increasing concern to service providers (SPs) and VPN customers. MPLS suffers from a number of security issues as soon as an attacker successfully penetrates the core. This paper provides an approach to enhance security in MPLS n...
With the rapid development of mobile applications, DRM systems used for mobile terminals and wireless environment become popular. However, the present DRM schemes are not fit for mobile applications because of the new security problems in wireless environment and the limitations of mobile terminals. In this paper, a trusted license distribution system based on IPSec VPN and its correlative issu...
We give the first constant factor approximation algorithm for the asymmetric Virtual Private Network (Vpn) problem with arbitrary concave costs. We even show the stronger result, that there is always a tree solution of cost at most 2·OPT and that a tree solution of (expected) cost at most 49.84 ·OPT can be determined in polynomial time. For the case of linear cost we obtain a (2+ε S )-approxima...
Network-based Intrusion Detection Systems (NIDSs) analyse network traffic to detect instances of malicious activity. Typically, this is only possible when the network traffic is accessible for analysis. With the growing use of Virtual Private Networks (VPNs) that encrypt network traffic, the NIDS can no longer access this crucial audit data. In this paper, we present an implementation and evalu...
در این مقاله به بررسی فنی و اقتصادی دستگاههای پایش وضعیت لحظهای برای آشکارسازی انواع عیوب موجود در دستگاه لوله مغزی سیار میپردازیم. عیبهای مکانیکی ایجاد شده در لوله مغزی سیار میتواند موجب ایجاد ترک و در نهایت شکست تیوب در دستگاه لوله مغزی سیار شود و این موضوع به شکل مؤثری بر فرایند تولید اثرگذار است. از اینرو، دستگاههای پایش وضعیت لحظهای در جلوگیری از شکست ناگهانی لوله مغزی سیار کمک فرا...
