Fault injection attacks are deliberate attempts to disrupt the normal operation of electronic devices or computer systems by introducing unexpected changes, such as glitches in power, timing, or environmental conditions. These disruptions can cause the device to behave unpredictably, often bypassing security checks or revealing sensitive information. Attackers use fault injection to exploit weaknesses in…

Side-Channel Attacks
Side-channel attacks are techniques used to gather information from a computer system by measuring physical effects during its operation, rather than by attacking weaknesses in algorithms or software directly. These effects can include timing information, power consumption, electromagnetic leaks, or even sounds made by hardware. Attackers analyse these subtle clues to infer secret data such…
Post-Quantum Cryptography
Post-Quantum Cryptography is a field of cryptography focused on developing encryption methods that can withstand attacks from quantum computers. Quantum computers are expected to be able to break many current cryptographic systems, making it essential to create new algorithms that remain secure. These new methods are designed to be implemented using existing computers and networks,…
Quantum-Resistant Cryptography
Quantum-resistant cryptography refers to methods of securing digital data so that it remains safe even if quantum computers become powerful enough to break current encryption. Traditional cryptographic systems, like RSA and ECC, could be easily broken by quantum computers using specialised algorithms. Quantum-resistant algorithms are designed to withstand these new threats, keeping data secure for…
Transport Layer Security (TLS) Optimisation
Transport Layer Security (TLS) optimisation refers to the process of improving the speed and efficiency of secure connections over the internet while maintaining strong security. It involves techniques such as reducing handshake times, reusing session data, and choosing faster cryptographic algorithms. The goal is to make encrypted communications as fast and seamless as possible for…
Cross-Origin Resource Sharing (CORS)
Cross-Origin Resource Sharing (CORS) is a security feature used by web browsers to control how resources on one website can be requested from another domain. It helps prevent malicious websites from accessing sensitive information on a different site without permission. CORS works by using special HTTP headers set by the server to specify which external…
OAuth Token Revocation
OAuth token revocation is a process that allows an application or service to invalidate an access token or refresh token before it would normally expire. This ensures that if a token is compromised or a user logs out, the token can no longer be used to access protected resources. Token revocation helps improve security by…
Secure Session Management
Secure session management refers to the methods and practices used to keep user sessions safe when interacting with websites or applications. This includes creating, maintaining, and ending sessions in a way that prevents attackers from hijacking or impersonating users. Techniques such as using unique session identifiers, enforcing timeouts, and securely storing session data help protect…
Protocol Fuzzing
Protocol fuzzing is a method used to test the security and reliability of communication protocols by automatically sending large amounts of random or unexpected data to them. This helps uncover hidden bugs, vulnerabilities, or weaknesses that might not be found through regular testing. By exposing how a protocol handles unusual input, developers can fix problems…
Reverse Engineering
Reverse engineering is the process of taking apart a product, system, or software to understand how it works. This can involve analysing its structure, function, and operation, often with the goal of recreating or improving it. It is commonly used when original design information is unavailable or to check for security vulnerabilities.
