A method and device for confirming authenticity of a public key infrastructure (PKI) transaction event between a relying node and a subject node in a communication network enables improved network security. According to some embodiments, the method includes establishing at a PKI event logging (PEL) server a process to achieve secure communications with the relying node (step 705). Next, the PEL server processes reported PKI transaction event data received from the relying node (step 710). The reported PKI transaction event data describe the PKI transaction event between the relying node and the subject node. The reported PKI transaction event data are then transmitted from the PEL server to the subject node (step 715). The subject node can thus compare the reported PKI transaction event data with corresponding local PKI transaction event data to confirm the authenticity of the PKI transaction event.
