Method and system for managing a distributed trust path locator for public key certificates relating to the trust path of an X.509 attribute certificate
InactiveUS7356690B2Data processing applicationsDigital data processing detailsPublic key certificatePKCS
A method and a system is presented for managing attribute certificates. An extension within an attribute certificate, called a distributed trust path locator, allows an attribute certificate to be physically disassociated from its supporting public key certificates while remaining logically associated with its supporting public key certificates. The user's attribute certificate and its supporting PKCs allows any server using an attribute certificate to locate and retrieve the PKC of the user and of the AC-issuing authority. The user is not required to communicate his / her PKC to a target service. In addition, configuring the target service to accept attribute certificates does not require the deployment of a PKC for every AC-issuing authority.

ActiveUS20090119182A1Expand the scope of servicesIdentity of with easeFinanceDigital data processing detailsInternet privacyE-commerce
A method and apparatus are provided for providing authentication of an e-commerce server to a user engaging in e-commerce transactions. When the user begins an e-commerce session, the e-commerce server requests an authentication token from an authentication proxy with which it has registered. If the authentication proxy recognizes the e-commerce server, the authentication proxy generates an authentication token in the form of a simple image, and sends the authentication token to the e-commerce server over a trusted path. The e-commerce server sends the authentication token to the user. The authentication proxy also sends a copy of the authentication token to the user over a second trusted path to a second device or application accessible by the user. The user can then see that the authentication token presented by the e-commerce server matches the authentication token presented by the authentication proxy. Since the user has received the two authentication proxies over separate channels, one of which is typically secure, the user can be assured that the e-commerce server has been authenticated by the authentication proxy, and that the e-commerce server is therefore legitimate.

A system for establishing a trusted path for secure communication between client devices and server devices, such as between an account holder and a financial institution, can provide the core security attributes of confidentiality (of the parties), integrity (of the information), anti-replay (protection against replay fraud) and / or anti-tampering (protection against unauthorized changes to information being exchanged and / or modules that generate and communicate such information). A messaging layer implementation in favor of a transport layer implementation can provide a trusted path. This infrastructure features secure cryptographic key storage, and implementation of a trusted path built using the cryptographic infrastructure. The trusted path protects against unauthorized information disclosure, modification, or replays. These services can effectively protect against Man-in-the-Middle, Man-in-the-Application, and other attacks.
