Dolev-Yao Attacker Model & Symbolic Crypto
Model a cryptographic protocol under Dolev-Yao assumptions.
The Dolev-Yao Model
Proposed by Danny Dolev and Andrew Yao in 1983, the Dolev-Yao model is the standard adversary model for symbolic protocol analysis. The attacker controls the entire network.
Attacker Capabilities
The Dolev-Yao attacker can: intercept any message, store messages, replay old messages, forge new messages from known components, but cannot break the underlying crypto primitives.
