Abstract
A platform security system and method improve security by binding an identity of a self-contained certificate signing request (SC CSR) requestor to the SC CSR to prevent malicious tampering, such as man-in-the-middle attacks. In at least one embodiment, the requestor, such as a client computer system or other source of a request, requests certificates from a certificate authority (CA). Binding the identity of the SC CSR to the requestor can prevent unauthorized system and/or data access and potentially resultant unauthorized access, malicious tampering, such as man-in-the-middle attacks, and other unauthorized actions or observations. Validation can be performed at the CA on the SC CSR to determine the integrity of the requestor and authorization to receive certificates before the CA sends the certificate to the requestor.
