How does YINYI work?
When you activate your YINYI protection, it quickly builds an encrypted tunnel that connects you to one of our secure Internet gateways. All the data you send and receive is now sent to the Internet using this encrypted tunnel that YINYI created. You are also assigned a temporary and random private IP address. This private IP address cannot be traced by anyone through our server and no one can find your real IP address or location.
Does YINYI work everywhere?
Yes, YINYI will work everywhere if you have a stable and fast Internet connection.
Is **YINYI** a VPN (Virtual Private Network)?
Yes – the technical term for YINYI is a VPN – a Virtual Private Network. Most large companies have a VPN which is supported by their IT departments to protect corporate communications. A VPN secures and encrypts data across a network, usually the Internet, by building an “encrypted tunnel.” Data passes through this tunnel which protects the data from getting intercepted by anyone. Even if the data is intercepted, it is in encrypted format and appears as scrambled, senseless text to anyone without the encryption keys. Your protection and privacy is not limited to just browsing. YINYI's VPN service encrypts all your Internet data to and from our VPN gateways, including instant messaging, streaming, VoIP, and email.
Do I need an Internet connection to use **YINYI**?
Yes, you need an Internet connection to use YINYI. YINYI sends a secure encrypted "tunnel" through an existing Internet connection. Using our software, you still connect to the Internet and then connect to our VPN which then secures and encrypts any data transmitted from your mobile device back to our server.
Why has my IP address changed?
YINYI establishes a connection from your computer to our servers in order to make your connection secure. All your browser traffic is routed through our secure servers. Therefore, you have been assigned the IP address of one of our servers. As a result, your IP location will appear as if you are surfing from the server's location. An IP (or Internet Protocol) address is a computer or device's address on the Internet that can identify its geographical location.
Can I enter sensitive information (such as my credit card number) while browsing the Internet?
Yes, it is safe to post information such as your credit card information when browsing the Internet. YINYI uses 256-bit encryption to protect your private credit card information.
What is your policy regarding government requests for information?
We take seriously the privacy of your data. We do not monitor any of your online communications. So if any government was ever to subpoena our server records, we have virtually no information to give them. We do maintain a set of usage logs, including time on and off our network and total bytes transmitted. This information is necessary to manage our server network, but is of little interest or value to law enforcement. Thus far, we have received no requests from any government for information about our users. If we ever receive such a request, it is our policy is to both require a subpoena and to notify users of requests for their information prior to disclosure unless we are prohibited from doing so by statute or court order.
Does YINYI monitor my Internet activity?
Do you share my private information with any other company?
No. Absolutely not.
Apple designed the iOS platform with security at its core. When we set out to create the best possible mobile platform, we drew from decades of experience to build an entirely new architecture. We thought about the security hazards of the desktop environment, and established a new approach to security in the design of iOS. We developed and incorporated innovative features that tighten mobile security and protect the entire system by default. As a result, iOS is a major leap forward in security for mobile devices.
Designed for students and professionals, this text introduces the major concepts of cybersecurity using numerous examples and practical applications.

To control the world by controlling the Internet has been a dominant strategy of the US. From the networkinfrastructure protection of the Clinton era to the network anti-terrorism of the Bush era and to the "networkdeterrence" of the Obama era, the national information security strategy of the US has evolved from a preventative strategy to a preemptive one.
Cryptography is the science of usingmathematics to encrypt and decrypt data. Cryptography enables you to storesensitive information or transmit it across insecure networks (like theInternet) so that it cannot be read by anyone except the intended recipient. Cryptographicstrength is measured in the time and resources it would require to recover theplaintext. The result of strong cryptography is cipher text that is verydifficult to decipher without possession of the appropriate decoding tool. Acryptographic algorithm, or cipher, is a mathematical function used in theencryption and decryption process. A cryptographic algorithm works incombination with a key — a word, number, or phrase — to encrypt the plaintext.The same plaintext encrypts to different cipher text with different keys. Thesecurity of encrypted data is entirely dependent on two things: the strength ofthe cryptographic algorithm and the secrecy of the key. With growing dependencieson secure information transfer and data security in this information age therequirement for a strong method of securing data is always in demand. In thisproject , we have tried to device a new means of securing data by encryptionand decryption in GF. The reason for using GF is that much research hasbeen done on GF but the GF field is still mostly untouched. Hence thereis much scope for designing versatile techniques which will be both secure andfaster. This will again reduce the probability of anonymous decryption byundesirable agents. Such technique can be the future of data security with wideapplication in every field starting with military application, internetsecurity, wireless data transfer and many more.
Every iOS device combines software, hardware, and services designed to work together for maximum security and a transparent user experience. iOS protects not only the device and its data at rest, but the entire ecosystem, including everything users do locally, on networks, and with key Internet services.
As the field of cybersecurity has moved beyond computer networks and the Internet into phones, the Internet of Things, and autonomous vehicles, it advocates a comprehensive approach to security that emphasizes not only techniques but also the mindset.

iOS and iOS devices provide advanced security features, and yet they’re also easy to use. Many of these features are enabled by default, so IT departments don’t need to perform extensive configurations. And key security features like device encryption aren’t configurable, so users can’t disable them by mistake. Other features, such asTouch ID, enhance the user experience by making it simpler and more intuitive to secure the device.
The book includes an introduction to networks, backups, history of the field, career information, and a glossary of key terms including US government acronyms.
