Patent number: 11924193Abstract: Techniques are disclosed for accelerating online certificate status protocol (OCSP) response distribution to relying parties using a content delivery network (CDN). A certificate authority generates updated OCSP responses for OCSP responses cached in the CDN that are about to expire. In addition, the certificate authority pre-generates cache keys in place of CDNs generating the keys. The certificate authority sends the OCSP responses and the cache keys in one transaction, and the CDN, in turn, consumes the new OCSP responses using the cache keys.Type: GrantFiled: December 22, 2021Date of Patent: March 5, 2024Assignee: DigiCert, Inc.Inventors: Richard F. Andrews, Quentin Liu

Patent number: 11251974Abstract: A method of provisioning a first digital certificate and a second digital certificate based on an existing digital certificate includes receiving information related to the existing digital certificate. The existing digital certificate includes a first name listed in a Subject field and a second name listed in a SubjectAltName extension. The method also includes receiving an indication from a user to split the existing digital certificate and extracting the first name from the Subject field and the second name from the SubjectAltName extension of the existing digital certificate. The method further includes extracting the public key from the existing digital certificate, provisioning the first digital certificate with the first name listed in a Subject field of the first digital certificate and the public key, and provisioning the second digital certificate with the second name listed in a Subject field of the second digital certificate and the public key.Type: GrantFiled: January 25, 2013Date of Patent: February 15, 2022Assignee: DigiCert, Inc.Inventors: Quentin Liu, Marc Williams, Richard F.

Patent number: 10288432Abstract: The disclosed computer-implemented method for guiding users to network-enabled devices may include (i) monitoring network communications within a wireless network, (ii) determining, based on monitoring network communications transmitted over the wireless network that involve a network-enabled device connected to the wireless network, that an end user requires guidance to a physical location of the network-enabled device, (iii) deriving the physical location of the network-enabled device in three-dimensional space, and (iv) guiding, by a user interface, the end user to the physical location of the network-enabled device in three-dimensional space. Various other methods, systems, and computer-readable media are also disclosed.Type: GrantFiled: June 15, 2017Date of Patent: May 14, 2019Assignee: Symantec CorporationInventors: Ilya Sokolov, Keith Newstadt, Richard F.

Patent number: 10110592Abstract: Techniques are disclosed for accelerating online certificate status protocol (OCSP) response distribution to relying parties using a content delivery network (CDN). A certificate authority generates updated OCSP responses for OCSP responses cached in the CDN that are about to expire. In addition, the certificate authority pre-generates cache keys in place of CDNs generating the keys. The certificate authority sends the OCSP responses and the cache keys in one transaction, and the CDN, in turn, serves requests for the OCSP responses using the cache keys. For new certificates, a private CDN is pre-populated with an OCSP response for a certificate concurrent with that certificate being issued. Doing so effectively uses the PCDN as an origin server for OCSP responses, reducing CA infrastructure needs.Type: GrantFiled: December 19, 2013Date of Patent: October 23, 2018Assignee: DigiCert, Inc.Inventors: Hari Veladanda, Ning Chai, Richard F.

Patent number: 9794248Abstract: A method for managing payment of digital certificates includes receiving a request to issue a digital certificate to a subscriber, capturing and saving payment information of the subscriber, performing a first authentication and verification of the subscriber at a first time, and performing at least one additional authentication and verification of the subscriber at least once every authentication period. A long-lived certificate is issued to the subscriber provided the subscriber is authenticated and verified. The long-lived certificate is valid for an expiration period. However, the long-lived certificate is revoked if (1) the additional authentications and verification produce invalid results, or (2) if payment is not received during a payment period. The authentication period is shorter than the expiration period and there are at least a first and a second authentication period within the expiration period. The expiration period is longer than the authentication period.Type: GrantFiled: December 23, 2009Date of Patent: October 17, 2017Assignee: Symantec CorporationInventors: Quentin Liu, Kathleen Elizabeth Barnes, Richard F.

Patent number: 9680819Abstract: A method of renewing a plurality of digital certificates includes receiving, at a first time, a request from a user to renew a first digital certificate and determining an expiration date for the first digital certificate. The method also includes receiving, at a second time, a request from the user to renew a second digital certificate and determining an expiration date for the second digital certificate. The expiration date for the second certificate is later than the expiration date for the first certificate. The method further includes determining a new expiration date occurring after the first time and the second time and renewing the first digital certificate. An expiration date for the renewed first digital certificate is equal to the new expiration date. Moreover, the method includes renewing the second digital certificate. An expiration date for the renewed second digital certificate is equal to the new expiration date.Type: GrantFiled: December 23, 2009Date of Patent: June 13, 2017Assignee: Symantec CorporationInventors: Quentin Liu, Kathleen Barnes, Richard F.

Patent number: 9100191Abstract: A method for forming a digital certificate includes receiving contact information associated with the digital certificate. The contact information includes at least a name, a mailing address, and an email address. The method also includes receiving billing information associated with the digital certificate and receiving a Certificate Signing Request (CSR) for the digital certificate. The method further includes receiving a first name for use in forming the digital certificate and receiving a second name for use in forming the digital certificate. Moreover, the method includes receiving an indication of a vendor of web server software, receiving an indication of a service period for the digital certificate, and forming the digital certificate. The first name is stored in a Subject field of the digital certificate and the second name is stored in the SubjectAltName extension of the digital certificate.Type: GrantFiled: January 25, 2013Date of Patent: August 4, 2015Assignee: Symantec CorporationInventors: Quentin Liu, Marc Loren Williams, Richard F.

Patent number: 9055059Abstract: A method of combining digital certificates at a prescheduled time is provided. The method includes receiving, by a processor, data from a first certificate and data from a second certificate and determining a certificate combination date. The certificate combination date directs a combining of the first certificate and the second certificate to form a combined certificate. The method further includes detecting the occurrence of the certificate combination date and combining the first certificate and the second certificate to form the combined certificate in response to detecting the occurrence of the certificate combination date.Type: GrantFiled: March 31, 2014Date of Patent: June 9, 2015Assignee: Symantec CorporationInventors: Kokil Bhalerao, Quentin Liu, Marc Williams, Richard F.
