Replay Attack Prevention
Meaning ⎊ Security measures using nonces or timestamps to ensure that a transaction cannot be processed more than once.
Deterministic Signatures
Meaning ⎊ A signing method that produces the same signature for the same message, eliminating risks from poor randomness.
Two-Factor Authentication
Meaning ⎊ Security process requiring two distinct forms of identification to verify user identity and authorize access.
Input Validation
Meaning ⎊ The practice of verifying all external data to ensure it meets expected criteria before processing it in a smart contract.
Hardware Security Module Integration
Meaning ⎊ The use of tamper-resistant physical hardware to perform cryptographic operations and securely store private keys.
Offline Signing Process
Meaning ⎊ A transaction workflow that separates the signing phase from the online environment to protect private keys from exposure.
Vault Infrastructure
Meaning ⎊ Centralized secure systems for storing, managing, and auditing access to sensitive credentials and secrets.
Isolated Execution Domain
Meaning ⎊ A hardware-protected partition that executes sensitive code independently from the host operating system.
MPC Multi-Party Computation
Meaning ⎊ A protocol allowing multiple parties to compute a result, like a signature, without ever exposing their individual inputs.
Multi-Party Computation (MPC)
Meaning ⎊ A cryptographic protocol allowing multiple parties to compute a result without revealing their individual private inputs.
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.
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.
