Please submit a ticket to contact Tencent Cloud engineers for certificate revocation. For more information on revocation processes of domain validation (DV) certificates, see DV Certificate Revocation ©2013-2017 Tencent Cloud. All rights reserved. Page 4 of 17 FAQ Product Introduction Why Would Security Review Fail? If the following prompt appears when applying for a Domain Validation (DV) SSL certificate, it indicates that the domain name failed to pass the security verification. DV SSL certificates cannot be issued via the rapid review process of Symantec CA for the domain name. Please purchase paid certificates. The specific reasons for failed security verification: According to the anti-phishing mechanism of CAs, sensitive words contained in domain names, such as bank and pay, can cause failed security verifications. Specific sensitive words are defined by CAs. And some less commonly used root domain names may also fail to pass verifications. For example, root domain names with .pw suffix, such as www.qq.pw and www.qcloud.pw , will fail to pass the verification. Because DV SSL certificates are quickly issued through automatic authentication without manual intervention, the verification standards are strengthened with more stringent sensitive words. ©2013-2017 Tencent Cloud. All rights reserved. Page 5 of 17 FAQ Product Introduction The Site Prompts "Connection Is Untrusted"? After the SSL certificate is deployed, the accessed site prompts "Connection is not secure". Is the certificate deployment failed? A: The certificate has been successfully deployed. This problem occurs because that the browser considers the sites unsafe if they use HTTPS protocol and their pages contain unencrypted HTTP contents. In this case, the code needs to be modified. For frontend modification, here are the references: 1. Reference resources with relative paths; 2. When referencing the absolute path, use // to reference resources. For example: //img.qcloud.com/example.png indicates compliance with the protocol of the current page, and the browser will automatically complete it. ©2013-2017 Tencent Cloud. All rights reserved.

Secure Sockets Layer (SSL) is a security protocol designed to ensure security and data integrity for Internet communications. Based on the SSL protocol, an SSL certificate can be installed on the server to achieve encrypted data transfer. Certificate authorities (CAs) are third-party authorities that verify the validity of public keys. They are responsible for specifying policies and procedures to verify users' identities, sign SSL certificates, and ensure the identity of a certificate holder and ownership of a public key. CAs issue SSL certificates for each user using the public key. A SSL certificate is used to certify that individuals/businesses listed in the certificate lawfully own the public key listed in the certificate. Digital signatures from CAs can prevent certificates from being forged and tampered. An SSL certificate actually represents the verification of the public key from an CA, which contains digital certificate-signing authority information, user information of the public key, the public key, authority signature, and expiration date. ©2013-2017 Tencent Cloud. All rights reserved. Page 10 of 17 FAQ Product Introduction What's Private Key？ SSL certificates are developed based on public-key cryptography, which encrypts information with digital keys so that the information can only be read by intended recipients after decryption. A key pair consists of a public key and a private key. The public key may be publicly distributed by a user, while the private key is kept by the user. Information that is encrypted with the public key can be decrypted only with the corresponding private key, and vice versa. An SSL certificate actually represents the verification of the public key from an CA, which contains digital certificate-signing authority information, user information of the public key, the public key, authority signature, and expiration date. ©2013-2017 Tencent Cloud. All rights reserved. Page 11 of 17 FAQ Product Introduction What's CSR? CSR is short for Certificate Signing Request. To obtain an SSL certificate, you need to generate a CSR file first and submit it to a certificate authority (CA). The CSR includes a public key and a distinguished name. CSR is typically generated from a web server and a public/private key pair for encryption and decryption will be created at the same time. Relevant organization information is required to create a CSR. The web server creates a distinguished name based on the information

  • Data Politics;Worlds, Subjects, Rights;
    DATA POLITICS Data has become a social and political issue because of its capacity to reconfigure relationships between states, subjects, and citizens. This book explores how data has acquired such an important capacity and examines how critical interventions in its uses in both theory and practice are possible. Data and politics are now inseparable: data is not only shaping our social relations, preferences, and life chances but our very democracies. Expert inter- national contributors consider political questions about data and the ways it provokes subjects to govern themselves by making rights claims. Concerned with the things (infrastructures of servers, devices, and cables) and language (code, programming, and algorithms) that make up cyberspace, this book demonstrates that without understanding these conditions of possibility it is impossible to intervene in or to shape data politics. Aimed at academics and postgraduate students interested in political aspects of data, this volume will also be of interest to experts in the fields of internet studies, international studies, Big Data, digital social sciences, and humanities.

  • Understanding Quality of Experiences on Different Mobile Browsers
    Understanding Quality of Experiences on Different Mobile Browsers: Measurements, Analysis, and Implications Yun Ma and Shuailiang Dong Abstract The web browser is one of the major channels to access the Internet on mobile devices. Based on the smartphone usage logs from millions of real-world Android users, it is interesting to find that about 38% users have more than one browser on their devices. However, it is unclear whether the quality of browsing experiences are different when visiting the same webpage on different browsers. In this paper, we collect 3-week consecutive traces of 337 popular webpages on three popular mobile browsers: Chrome, Firefox, and Opera. We first use a list of metrics and conduct an empirical study to measure the differences of these metrics on different browsers. Then, we explore the variety of loading time and cache performance of different browsers when visiting the same webpage, which has a great impact on the browsing experience. Furthermore, we try to find which metrics have significant effect on the differences, investigating the possible causes. Finally, according to our findings, we give some recommendations to web developers, browser vendors, and end users. 1 Introduction Web browsing is always the major requirement of Internet users. Recent reports show that the number of smartphone users worldwide has been over 2.6 billion, and the web traffic volume from mobile devices has exceeded that from desktop PCs. Compared to desktop PCs, web browsing on smartphones considers more on the quality of experiences (QoE): not only the look-and-feel and page loading time, but also the data traffic and energy consumption.

  • Playing Fair in the Privacy Sandbox: Competition, Privacy, and Interoperability Standards
    Playing fair in the Privacy Sandbox: competition, privacy, and interoperability standards Mark Nottingham* Abstract Google’s Privacy Sandbox proposals to change the Chrome browser in ways that are likely to further advantage them over other publishers and advertising platforms has attracted the attention of competition regulators, the online advertising industry, and critics of their platform power. At the same time, the Privacy Sandbox appears to answer a call from data protection regulators, privacy advocates and users for ‘privacy by design,’ moving in lockstep with its industry peers. How, then, should this behaviour be evaluated for abuse? I argue that there are several hurdles to considering the most controversial Privacy Sandbox proposal – blocking third-party cookies – as an abuse of market power. Furthermore, I propose that, because web browsers are an architecturally regulated market, competition regulators should distinguish unilateral behaviour by examining it in the context of other browsers’ behaviours, along with signals regarding consensus from the relevant standards bodies. I Introduction The UK Competition and Markets Authority (CMA) recently announced an investigation into Google’s Privacy Sandbox proposals1 because of their potential to ‘undermine the ability of publishers to generate revenue and undermine competition in digital advertising, entrenching Google’s market power.’2 Geradin, Katsifis, and Karanikioti support this view, concluding that ‘Chrome’s policy change raises… antitrust concerns, in that it may distort * Mark Nottingham is a student at Melbourne Law School, Chair of the IETF HTTP Working Group, and recently a member of the Internet Architecture Board.

  • Security Evaluation of Multi-Factor Authentication in Comparison with the Web Authentication API
    Hochschule Wismar University of Applied Sciences Technology, Business and Design Faculty of Engineering, Department EE & CS Course of Studies: IT-Security and Forensics Master’s Thesis for the Attainment of the Academic Degree Master of Engineering (M. Eng.) Security Evaluation of Multi-Factor Authentication in Comparison with the Web Authentication API Submitted by: September 30, 2019 From: Tim Brust born xx/xx/xxxx in Hamburg, Germany Matriculation number: 246565 First supervisor: Prof. Dr.-Ing. habil. Andreas Ahrens Second supervisor: Prof. Dr. rer. nat. Nils Gruschka Purpose of This Thesis The purpose of this master’s thesis is an introduction to multi-factor authentication, as well as to the conventional methods of authentication (knowledge, possession, biometrics). This introduction includes technical functionality, web usability, and potential security threats and vulnerabilities. Further, this thesis will investigate whether the Web Authentication API is suit- able as an alternative or possible supplement to existing multi-factor authentication methods. The question has to be answered to what extent the Web Authentication API can increase security and user comfort. An evaluation of the security of the Web Authentication API in comparison with other multi-factor authentication solutions plays a crucial role in this thesis. Abstract Internet users are at constant risk, given that data breaches happen nearly daily. When a breached password is re-used, it renders their whole digital identity in dan- ger. To counter these threats, the user can deploy additional security measures, e.g., multi-factor authentication. This master’s thesis introduces and compares the multi- factor authentication solutions, one-time passwords, smart cards, security keys, and the Universal Second Factor protocol with a focus on their security.
