Formal Security Analysis

Definition

Formal security analysis employs rigorous mathematical and logical methods to prove the correctness and security properties of cryptographic protocols and blockchain systems. This analytical approach uses formal verification techniques to identify potential vulnerabilities or logical flaws that might be missed by empirical testing. It provides a high degree of assurance regarding a system’s resilience against attacks.
