Abstract: A process of issuing a limited-use electronic certificate. In operation, a public key infrastructure (PKI) device receives a request for an electronic certificate from an end entity. The PKI device detects an anomaly with respect to the request received from the end entity. The PKI device generates, based on the detected anomaly, a limited-use electronic certificate. The PKI then issues the limited-use electronic certificate to the end entity. When the end entity determines that the issued certificate is a limited-use certificate with limited-use attributes such as a shortened validity period or lowered assurance level, the end entity provides a visual and/or audio prompt indicating the issuance of the limited-use certificate and further including one or more corrective actions to be performed to eliminate the anomaly prior to sending a new request for an electronic certificate to the PKI device.
