📌 Identity-Based Encryption Summary
Identity-Based Encryption (IBE) is a method of encrypting messages so that a person’s public key can be derived from their unique identity, such as their email address. This removes the need for a traditional public key infrastructure where users must generate and exchange certificates. Instead, a trusted authority uses the identity information to create the necessary cryptographic keys for secure communication.
🙋🏻♂️ Explain Identity-Based Encryption Simply
Imagine sending a locked box to a friend where their email address is the key to open it. You do not need to arrange for a special key in advance because their email itself acts as the key. This makes it much easier to send private messages without worrying about sharing complicated codes first.
📅 How Can it be used?
You could use IBE to allow users to send encrypted emails without managing complex key exchanges or certificates.
🗺️ Real World Examples
A company implements IBE so employees can send confidential emails simply by using each other’s work email addresses. The system automatically encrypts messages and ensures only the intended recipient, who can prove their identity, can read them.
A secure messaging app uses IBE to let users start encrypted chats immediately by entering the recipient’s username. There is no need for either person to manually exchange public keys or set up certificates.
✅ FAQ
How does Identity-Based Encryption make sending secure emails easier?
With Identity-Based Encryption, you can use something as simple as an email address to encrypt messages, so you do not need to worry about swapping complicated certificates or keys. This makes it much more straightforward to send secure emails, as the system automatically creates the right keys based on the identity you want to contact.
Who provides the keys in Identity-Based Encryption?
A trusted authority, often called a Private Key Generator, takes care of creating and giving out the necessary keys for users. You do not have to generate your own keys, as the authority uses your identity information to do this for you, making the process less complicated for most people.
Is Identity-Based Encryption safe if someone knows my email address?
Knowing your email address alone is not enough for someone to read your encrypted messages. Only the trusted authority can create the special private key linked to your identity, so unless someone can access that key, your messages stay protected.

Conditional Generative Models
Conditional generative models are a type of artificial intelligence that creates new data based on specific input conditions or labels. Instead of generating random outputs, these models use extra information to guide what they produce. This allows for more control over the type of data generated, such as producing images of a certain category or text matching a given topic.
Weight Pruning Automation
Weight pruning automation refers to using automated techniques to remove unnecessary or less important weights from a neural network. This process reduces the size and complexity of the model, making it faster and more efficient. Automation means that the selection of which weights to remove is handled by algorithms, requiring little manual intervention.
Experience Mapping
Experience mapping is a method used to visually represent a person's journey through a service, product, or process. It highlights what users do, think, and feel at each stage, helping teams understand their experiences and identify pain points. This approach supports better decision-making by showing where improvements could make the biggest difference for users.
Keyword Boost
Keyword Boost is a strategy used in digital marketing and search engine optimisation to increase the visibility of specific words or phrases within online content. By focusing on these targeted keywords, websites can attract more visitors searching for related topics. This can involve adjusting website text, blog posts, or advertisements to feature the chosen keywords more prominently.
Data Catalog Strategy
A data catalog strategy is a plan for organising, managing and making data assets easy to find within an organisation. It involves setting rules for how data is described, labelled and stored so that users can quickly locate and understand what data is available. This strategy also includes deciding who can access certain data and how to keep information up to date.
