In general, every proposed solution has possed a real challenge to the existing formal methods of protocol analysis and verification. The main goal of this work is the proposal of a logic to reason about privacy-enhancing monotonic and non-monotonic cryptography protocols. The new logic will be called L-PEP and it extends the existing Rubin's logic of beliefs. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-642-19348-4\_9} \end
