Private Set Intersection

Private Set Intersection is a cryptographic technique that allows two or more parties to find common elements in their data sets without revealing any other information. Each party keeps their data private and only learns which items are shared. This method is useful when data privacy is important but collaboration is needed to identify overlaps.

Secure Enclave Encryption

Secure Enclave Encryption refers to a security technology that uses a dedicated hardware component to protect sensitive information, such as passwords or cryptographic keys. This hardware, often called a Secure Enclave, is isolated from the main processor, making it much harder for hackers or malware to access its contents. Devices like smartphones and computers use…

Quantum-Safe Blockchain

Quantum-safe blockchain refers to blockchain systems designed to withstand attacks from quantum computers. These computers could potentially break traditional cryptographic methods, making current blockchains vulnerable. Quantum-safe blockchains use new forms of cryptography that are resistant to quantum attacks, ensuring long-term security for transactions and data.

Key Ceremony Processes

Key ceremony processes are carefully organised procedures used to generate, distribute, and manage cryptographic keys in secure systems. These ceremonies are designed to ensure that no single person has complete control over the keys and that all steps are transparent and auditable. They often involve multiple participants, secure environments, and detailed documentation to prevent unauthorised…

Entropy Pool Management

Entropy pool management refers to the way a computer system collects, stores, and uses random data, known as entropy, which is essential for creating secure cryptographic keys and random numbers. Systems gather entropy from various unpredictable sources, such as mouse movements, keyboard timings, or hardware events, and mix it into a pool. This pool is…

Secure Random Number Generation

Secure random number generation is the process of creating numbers that are unpredictable and suitable for use in security-sensitive applications. Unlike regular random numbers, secure random numbers must resist attempts to guess or reproduce them, even if someone knows how the system works. This is essential for tasks like creating passwords, cryptographic keys, and tokens…

Cryptographic Agility

Cryptographic agility is the ability of a system or application to quickly and easily switch between different cryptographic algorithms or protocols. This flexibility is important because older algorithms can become insecure over time as new vulnerabilities are discovered. By designing systems with cryptographic agility, organisations can update their security measures without having to rebuild or…
