Ideas

These are the ideas of my own:

Idea 1: Usage of End-to-End Encryption Instant Messaging softwares in IPv6 Only Environments

Category : This is an interdisciplinary topic associated with Computer Networks and Cybersecurity .
Brief Description: I think there is no need to say something more about the usage of E2EE IM Softwares in IPv4 Environment. However, what is the condition in IPv6 Environment, especially IPv6-Only Environment?
Reference:

  1. Overview of Mobile IPv6 Security (IEEE ISMS 2012)
  2. Privacy and security in IPv6 networks: challenges and possible solutions. (ACM SIN 2013)
  3. Overview and Analysis the Performance of Security in Mobile IPv6 (IEEE ICCCA 2020)
  4. Vizard: A Metadata-hiding Data Analytics System with End-to-End Policy Controls (ACM CCS 2022)
  5. End-to-End Encrypted Cloud Storage in the Wild: A Broken Ecosystem (ACM CCS 2024)
  6. Nemesis: Combating Abusive Information in Encrypted Messaging with Private Reporting (ESORICS 2024)

  7. Implementing full Internet IPv6 end-to-end encryption based on Cryptographically Generated Address (TOR Project)

    Moreover, There are some projets concerning this passage, I shall list them as follows.

  8. Project Yggdrasil on GitHub
  9. Project CJDS on GitHub

Idea 2: Random Order Models’ Coloring in the Bipartite Graphes

Category : This is a topic associated with Theoretical Computer Science .
Brief Description : We have already known that the situation in Deterministic Order Models’ Coloring in the Bipartite Graphes. However, how come when the situation changes to the Random Order Model? This is a question we would like to consider.
Reference:

  1. First-Fit Coloring of Forests in Random Arrival Model (MFCS 2024)

    Moreover, the second author of this paper previously gave one academic report at Zhejiang Normal University on May 8th, 2024. I shall upload the slides which were used in that report. We can visit the website at here .

  2. Coloring and Recognizing Mixed Interval Graphs (ISAAC 2023)
  3. Online Coloring of Short Intervals (APPROX/RANDOM 2020)

Idea 3: Revolving Doors among Virtual Youtubers, Idols and Livestreamers

Category : This is a topic associated with Human Computer Interactions .
Brief Description : Nowadays, we can see the activities by Virtual Youtubers, Idols and Livestreamers have become more and more popular. We can observe that it seems the revolving doors among them exist. How do we explain this phenomena in the new era? It is one question that we need to think about.
