Protocol Analysis

Purpose

Model cryptographic protocols as state machines, enumerate state transitions, and identify vulnerabilities including desynchronization, replay attacks, downgrade attacks, and session binding failures.

Scope Constraints

Reads protocol specifications, message sequence diagrams, and implementation source code. Does not modify files or execute code. Does not interact with live protocol endpoints or perform active testing.

Inputs

• Protocol specification or implementation under analysis
• Message sequence diagrams or protocol description
• Participant roles and trust relationships
• Security properties the protocol should provide (authentication, confidentiality, integrity, forward secrecy)
• Deployment context (network model, adversary capabilities)

Input Sanitization

No user-provided values are used in commands or file paths. All inputs are treated as read-only analysis targets.
