US Patent 8,745,378: Validated SCEP™ (VSCEP)

CSS receives patent for highly secure PKI certificate issuance. Delivers enhanced level of secure identity for devices outside of corporate firewall.

Cleveland, OH – July 10, 2014 – Certified Security Solutions, Inc. (CSS) on Tuesday announced the approval of US patent number 8,745,378, for their Validated SCEP™ (VSCEP) service used to protect SCEP (Simple Certificate Enrollment Protocol) certificate enrollment requests.

VSCEP was created in response to the SCEP vulnerability uncovered by Certified Security Solutions, Inc., published by US-CERT in 2012, Vulnerability Note VU#971035. In certain situations, organizations that use the Simple Certificate Enrollment Protocol (SCEP) for mobile devices are open to increased security risks that include fraudulent credentials and privilege escalation attacks.

Validated SCEP™ is a system and method for validating SCEP certificate enrollment. Validated SCEP™ verifies whether a certificate request is legitimate by comparing it to registered SCEP challenges and associated expected certificate request content. The addition of VSCEP to CSS’ Certificate Management System (CMS) makes it one of the most secure platforms to deliver certificates in the world of BYOD and IoT devices.

“We are thrilled to receive this official recognition of the uniqueness of our solution,” commented Ted Shorter, CSS CTO. “To put it simply, the VSCEP service helps ensure that certificate requestors really are who they say they are. This patent is a testament to the work of the tremendous team we have in place at CSS.”
