CP5603 Research Report Note: This Is Not A Group Project ✓ Solved

CP5603 Research Report Note: This is not a group project. Each

A major company has asked you to assess two similar technologies, from a big-picture view (without too much technical detail), to help them decide which alternative they should use. The general idea is for your report to:

1. Describe the two technologies (or more than two, if there are more).

2. Compare and contrast the two technologies. What are their good points and (more interestingly) their bad points or weaknesses?

3. Finally, what is your personal recommendation of which should a data-oriented company use? Explain why, perhaps by comparing their good points and bad points.

Any two similar technologies would be fine, below are some possible topics:

  • An employee is travelling to a country that blocks access to some web sites. Without using a VPN, which anonymous browser is best? Pick any two, and compare them: • The TOR browser • FreeBrowser • I2P browser • FreeNet
  • A certificate authority for an SSL/TLS key and certificate, or our own key server for our company, something like Kerberos protocol.
  • Which do you recommend a spy to use? • A hardware keylogger or • A software keylogger.
  • Undeniable signatures are where someone cannot deny that they sent a message. Describe two ways, and recommend what you think seems the best.
  • What should we use to prevent the U.S. Government from listening to your communication? Pick any two from: • LinPhone • SureSpot • ChatSecure • RedPhone • Telegram.
  • How to send large binary files to a colleague, in a secure way? Should I use: • Email attachments in MIME or • One-click hosting.
  • On the subject of cyberlocker web sites, which one do you think is best? Consider reviews of speed, end-to-end encryption availability, and government access.
  • Is systemd really all that bad? Should we use initd (or an alternative, like runitd) instead?
  • What is the difference (if any) between deep web and dark web?
  • What is the difference (if any) between bitcoin and other cryptocurrencies like Ethereum?

Paper For Above Instructions

In today's technologically driven world, the decision on the most suitable technology for a data-oriented company can significantly impact its operations. This report aims to compare two technologies that are increasingly relevant in the context of online privacy and anonymity: the TOR browser and the I2P (Invisible Internet Project) browser. Both of these technologies provide alternative means for users to access the internet anonymously, but they differ in functionality, usability, security, and target audience. This comparison will explore their respective strengths and weaknesses, ultimately leading to a recommendation for their adoption by data-oriented companies.

1. Description of the Technologies

The TOR browser is perhaps the most well-known tool for anonymous browsing on the internet. It operates by routing internet traffic through a global network of volunteer-operated servers, known as onion routers, which helps to conceal a user's location and usage from surveillance and traffic analysis. This layered approach to encryption provides a high degree of anonymity, making it attractive for users who wish to evade censorship and protect their privacy online (Danezis et al., 2017).

On the other hand, the I2P network offers a different approach to anonymity. It is primarily designed for anonymous peer-to-peer communication. Unlike TOR, which allows access to the regular internet anonymously, I2P is optimized for internal traffic within its own network, providing a platform for applications such as file sharing, email, and anonymous website hosting. It facilitates an environment where data can be sent and received anonymously using encryption methods (Peters, 2019).

2. Comparison and Contrast of the Technologies

When comparing the TOR and I2P browsers, several key factors emerge: effectiveness, ease of use, scope, and performance.

2.1 Effectiveness

TOR is highly effective for accessing the external internet anonymously, which makes it suitable for users in countries with high levels of censorship (Pérez, 2020). It is also supported by numerous transparency initiatives, reinforcing the trust users place in it. However, due to its reliance on volunteer nodes, the speeds can significantly vary based on network traffic and may not be suitable for all applications.

I2P, while also offering strong anonymity, excels in internal communications. It lacks the ability to easily access the regular internet but is preferred for scenarios requiring robust peer-to-peer communication and file sharing (Biryukov et al., 2016). However, the user base is smaller, which can impact performance and accessibility.

2.2 Usability

Usability is one area where the TOR browser outshines I2P. TOR is relatively straightforward to set up and use, even for individuals with limited technical expertise (Tor Project, 2021). Users simply need to download the browser and they can start accessing anonymized websites directly.

I2P, conversely, can involve a steeper learning curve due to its inherent complexity and the need for users to configure their applications correctly to take full advantage of its features. This could pose a barrier for less tech-savvy users (Srinivas et al., 2019).

2.3 Security

In terms of security, both technologies use strong encryption methods to conceal user activity and location, but they face different threats. TOR is vulnerable to certain attacks, such as exit node monitoring, which can compromise user data (Ming, 2018). I2P is inherently more secure for internal traffic and peer-to-peer communication due to its design, as no exit point is necessary for accessing external content. However, it still faces challenges including the potential for end-user misconfiguration (Vogt, 2020).

2.4 Performance

Performance can greatly affect user experience. TOR may experience slower speeds during peak usage times, as routing through multiple nodes can delay data transmission. This can be frustrating for users expecting high-speed connections (Berger, 2019). In contrast, while I2P is generally faster for internal data exchanges, its lesser popularity means relatively little traffic, which can sometimes work to its advantage; however, accessing external sites could lead to slower performance.

3. Personal Recommendation

In conclusion, while both TOR and I2P offer valuable anonymity solutions, their applicability varies depending on the specific needs of the user. For data-oriented companies primarily focused on accessing external internet resources safely and anonymously, the TOR browser is the recommended choice. Its ease of use, established community support, and effectiveness in bypassing internet censorship are compelling advantages.

However, for companies involved in activities requiring secure peer-to-peer communication and file sharing, especially where risk of exposure to external threats exists, I2P would serve as a superior option.

Ultimately, the optimal choice will depend on the context in which the technologies will be employed, highlighting the importance of understanding the specific advantages and limitations of each browser.
