📌 Session Keys Summary
Session keys are temporary encryption keys used to secure communication between two parties for a specific session or period of time. They help protect the privacy and integrity of data exchanged during that session. After the session ends, the session key is discarded and a new one is used for future sessions, making it harder for attackers to access sensitive information.
🙋🏻♂️ Explain Session Keys Simply
Imagine two friends using a secret code that changes every time they talk, so no one else can understand their messages. Even if someone figures out the code once, it will not work next time because the friends will use a new code. This is similar to how session keys keep online conversations private and secure.
📅 How Can it be used?
Session keys can be used in a web application to encrypt user data during each login session, protecting information from interception.
🗺️ Real World Examples
When you shop online, your browser and the website use session keys to encrypt credit card details and personal information during checkout. This ensures that only you and the website can read the sensitive data while it is being transmitted.
In secure messaging apps, each conversation session uses a unique session key so that even if someone intercepts the messages, they cannot read past or future conversations without the specific session key.
✅ FAQ
What is a session key and why is it important for online security?
A session key is a temporary encryption key used to keep information private while two people or systems are communicating. It is important because it helps protect your messages or data from being read by anyone else during that specific session. Once the session ends, the key is thrown away, making it much harder for anyone to crack past conversations or steal information.
How does using a session key make my data safer during online activities?
Session keys keep your data safer by making sure every conversation or connection gets its own unique key. If someone manages to get hold of one key, they can only see information from that one session, not everything you have ever sent or received. This limits the damage and keeps your private details much more secure.
Do I need to do anything to use session keys when I am browsing or sending messages?
You do not need to do anything special to use session keys. Most modern websites and messaging apps handle session keys automatically behind the scenes. They make sure your data is protected every time you start a new chat or session, so you can focus on what you are doing without worrying about the technical details.

Quantum Error Reduction
Quantum error reduction refers to a set of techniques used to minimise mistakes in quantum computers. Quantum systems are very sensitive to their surroundings, which means they can easily pick up errors from noise, heat or other small disturbances. By using error reduction, scientists can make quantum computers more reliable and help them perform calculations correctly. This is important because even small errors can quickly ruin the results of a quantum computation.
Graph Neural Network Pruning
Graph neural network pruning is a technique used to make graph neural networks (GNNs) smaller and faster by removing unnecessary parts of the model. These parts can include nodes, edges, or parameters that do not contribute much to the final prediction. Pruning helps reduce memory use and computation time while keeping most of the model's accuracy. This is especially useful for running GNNs on devices with limited resources or for speeding up large-scale graph analysis.
Bayesian Neural Networks
Bayesian Neural Networks are a type of artificial neural network that use probability to handle uncertainty in their predictions. Instead of having fixed values for their weights, they represent these weights as probability distributions. This approach helps the model estimate not just an answer, but also how confident it is in that answer, which can be important in situations where understanding uncertainty is crucial.
Customer Credit Risk Analytics
Customer credit risk analytics is the process of assessing how likely a customer is to repay borrowed money or meet credit obligations. It uses data and statistical methods to predict the chances that a customer will default on payments. This helps lenders and businesses make informed decisions about who to lend to and under what terms.
Application Rationalisation
Application rationalisation is the process of reviewing and evaluating an organisation's software applications to determine which should be kept, updated, replaced, or retired. This helps reduce unnecessary costs, complexity, and duplication by ensuring only the most valuable and effective applications are used. The goal is to streamline the technology environment, making it easier to manage and support.
