高效安全的基于闪存的游戏CAPTCH
Efficient and Secure Flash-based Gaming CAPTCH
摘要：
随着智能电网连接的增长、新应用的出现以及客户和能源云之间不断变化的交互，云更容易受到拒绝服务攻击。需要有效的检测方法来认证、检测和控制攻击者。CAPTCHA是一种区分计算机和人类的完全自动化公共图灵测试，是一种有效的阻止拒绝服务攻击的工具。服务器向用户提供一个客户端难题，以解决访问服务或网站。这个谜题对计算机来说应该足够难，但对人类来说很容易解决。已经提出了几种方法，包括流行的基于图像、基于视频和基于文本的CAPTCHA。在本文中，我们提出了一种新的基于Flash的游戏CAPTCHA来区分机器人和人类。我们提出了一个拖放客户端的难题，用户将玩一个简单的游戏来回答一个视觉问题。事实证明，我们的方法对用户来说很方便，对机器人来说很容易。此外，它具有游戏方面，这使得它对所有年龄段的用户都很有趣。
英文摘要：
With the growth of connectivity to smart grids, new applications, and the changing interaction between customer and energy clouds, clouds are more vulnerable to denial-of-service attacks. Efficient detection methods are required to authenticate, detect and control attackers. Completely Automated Public Turing test to tell Computers and Humans Apart, CAPTCHA, is one efficient tool to thwart denial of service attacks. The server presents the user with a client puzzle to solve in order to gain access to the service or website. The puzzle should be hard enough for computers, but easy for humans to solve. Several methods have been suggested including the popular image-based, as well as video-based, and text-based CAPTCHAs. In this paper, we present a new Flash-based gaming CAPTCHA to differentiate bots from humans. We propose a drag and drop client puzzle where the user will play a simple game to answer a visual question. Our method turns out to be convenient, easy for users and challenging for bots. Additionally, it has gaming aspect, which makes it interesting to users of all age groups.
