Diffie-Hellman (DH) symmetric encryption plays an important role in the network security, and the security proof for many protocols relies on the DH assumption. The Logic of Local Sessions (LLS) is a practical security protocol logic. With its automatic tool Security Protocol Verifier (SPV), LLS can verify many interesting properties for complex security(More)

We propose a computational semantics for a previously developed protocol security logic, Logic of Local Sessions (LLS), replacing its earlier symbolic semantics based on the Dolev-Yao model. With the new semantics, the protocol verification of LLS is more close to the real execution, while the proofs can still be carried out at a symbolic level using the(More)
