Check-Effects-Interactions Pattern
Meaning ⎊ A strict coding sequence requiring validation and state updates to occur before any external calls are made.
Mutex Lock Implementation
Meaning ⎊ A software guard that blocks multiple simultaneous function calls to prevent illegal state manipulation.
Reentrancy Guarding
Meaning ⎊ A locking mechanism preventing recursive function calls to stop attackers from draining funds during execution.
Reentrancy Guard
Meaning ⎊ Mechanism locking functions to prevent recursive calls that drain funds before state updates.
TLS Certificate Pinning
Meaning ⎊ A security method forcing an application to only connect to a server using a specific, pre-verified certificate.
Contract Call Authorization
Meaning ⎊ Verifying the legitimacy of an incoming transaction or function call before processing it.
Two-Factor Authentication
Meaning ⎊ Security process requiring two distinct forms of identification to verify user identity and authorize access.
Authentication and Authorization
Meaning ⎊ The core processes of verifying identity and defining the scope of permitted actions within a digital system.
Polynomial Interpolation
Meaning ⎊ A math method used to define a polynomial from points, essential for reconstructing secrets in threshold schemes.
Checks-Effects-Interactions Pattern
Meaning ⎊ A coding pattern that enforces state updates before external calls to prevent reentrancy and logic vulnerabilities.
Trusted Application
Meaning ⎊ Software specifically developed to run securely within a protected hardware environment for sensitive tasks.
Isolated Execution Domain
Meaning ⎊ A hardware-protected partition that executes sensitive code independently from the host operating system.
Root of Trust
Meaning ⎊ The foundational, immutable component of a security system that provides the basis for all trust and verification.
Trusted Execution Environment
Meaning ⎊ An isolated, secure processor area ensuring the confidentiality and integrity of sensitive code and data execution.
FIDO2 Standards
Meaning ⎊ Hardware-backed, phishing-resistant authentication protocol replacing traditional passwords with cryptographic keys.
Checks-Effects-Interactions
Meaning ⎊ Coding pattern requiring checks, then state updates, and finally external interactions to prevent reentrancy.
Hardware Security Module
Meaning ⎊ A specialized, tamper-proof physical device used to securely manage cryptographic keys and sensitive financial data.
Digital Signature
Meaning ⎊ Electronic verification method using cryptographic keys to confirm the authenticity and integrity of digital data.
Multi-Signature Verification
Meaning ⎊ Multi-Signature Verification provides a decentralized threshold mechanism to secure digital assets by requiring multiple keys for transaction approval.
