📌 Key Agreement Protocols Summary
Key agreement protocols are methods that allow two or more parties to create a shared secret key over a public communication channel. This shared key can then be used to encrypt messages, ensuring that only the intended recipients can read them. These protocols are important for secure online activities, such as banking or private messaging, where sensitive information needs to be protected from eavesdroppers.
🙋🏻♂️ Explain Key Agreement Protocols Simply
Imagine two friends who want to share secrets, but they can only talk where everyone can hear them. They use a clever method to agree on a password that only they know, even though everyone hears what they say. Key agreement protocols are like this special trick, making sure only the right people can understand each other.
📅 How Can it be used?
Use a key agreement protocol to enable secure data exchange between users in a messaging app.
🗺️ Real World Examples
When you use a secure website, like online banking, your browser and the bank’s server use a key agreement protocol, such as Diffie-Hellman, to create a shared key. This key is then used to encrypt your banking details and transactions, so no one else can read them.
In secure messaging apps like WhatsApp, key agreement protocols are used every time you start a new chat. The app ensures that only you and your contact have the secret key needed to read the messages, even if someone tries to intercept them.
✅ FAQ
What is a key agreement protocol and why is it important?
A key agreement protocol is a way for two or more people to create a secret password together, even if they are talking over the internet where others might be listening. This shared secret lets them send messages privately, which is vital for things like online banking or chatting with friends without anyone else being able to read what they are saying.
How does a key agreement protocol keep my information safe online?
Key agreement protocols make sure that only you and the person you are communicating with can read your messages. Even if someone manages to listen in on your conversation, they will not be able to understand the information because they do not have the secret key you both created.
Where might I use a key agreement protocol in everyday life?
You use key agreement protocols more often than you might think, such as when you log in to your bank online, send a private message, or shop on a secure website. These protocols work in the background to make sure your personal details and conversations stay private.

AI for Dynamic Pricing
AI for Dynamic Pricing refers to using artificial intelligence systems to automatically adjust the price of products or services in real time. These systems analyse factors such as demand, supply, competitor prices, and customer behaviour to set the most effective price at any given moment. The aim is to maximise sales, profits, or both, while responding quickly to market changes.
Employee Engagement
Employee engagement refers to how committed and motivated employees feel towards their work and the organisation they work for. It covers how enthusiastic they are, how connected they feel to their team, and how likely they are to go above and beyond in their roles. High employee engagement often leads to better performance, lower staff turnover, and a more positive workplace culture.
Data Anonymization Pipelines
Data anonymisation pipelines are systems or processes designed to remove or mask personal information from data sets so individuals cannot be identified. These pipelines often use techniques like removing names, replacing details with codes, or scrambling sensitive information before sharing or analysing data. They help organisations use data for research or analysis while protecting people's privacy and meeting legal requirements.
AI for Personalised Education
AI for personalised education uses artificial intelligence to adapt learning materials and experiences to the needs of each individual student. It analyses data such as learning pace, strengths, weaknesses, and preferences to create customised lessons and support. This approach helps students learn more effectively by focusing on areas where they need the most help and providing content in ways they find engaging.
