  • Publication number: 20170070353
    Abstract: A method for deploying credentials in a server and a client system including three devices. The second device has primary credentials including a public key, a private key and a primary certificate. After successful authentication of a user, the first device generates a new private key/public key pair and wraps the new private key. After successful authentication of the user, the second device derives a new certificate comprising the new public key, the new certificate having the same usage specified in the primary certificate. The second device signs the new certificate using the private key of the primary credentials. The third device forwards to the server the primary certificate and the new credentials combining the new public key, the wrapped private key and the new certificate. The server verifies the chain of trust of the new credentials and, in case of successful verification, associates the new credentials to the user.

  • Publication number: 20150341340
    Abstract: Method and System for enhanced privacy in privacy-preserving identity solutions. The technology provides for a redirect of a request to generate a proof of an attribute from a service provider to a separator. The separator removes source identification from the attribute-proof request and redirects the attribute-proof request, free of original source identification, to a credential issuer which issues the credential. A security device of the user generates a presentation token from the privacy-preserving credential and presents the presentation token to the service provider as proof of the attribute. Other systems and methods are disclosed.

  • Patent number: 9124563
    Abstract: A method to securely and asynchronously provisioning keys from one source secure device to a target secure device through a key provisioning server, in which the keys to be provisioned via the method remain unknown. The method includes the steps of, for the source secure device, encrypting a key to be transferred using a transport key so that only the target secure device can decrypt, and sending the encrypted key to the provisioning server and, for the target secure device, when available, getting the encrypted transferred key, and decrypting the transferred key using the transport key.

  • Publication number: 20150097698
    Abstract: A remote server is connected to at least one energy box, each energy box being connected to at least one energy consuming device, and each energy box being connected to a metering device. The remote server sends to the energy box a transaction demand. The energy box sends to at least one energy consuming device an energy consumption reduction request. The metering device measures energy consumption of the energy consuming device. The metering device sends to the energy box the measured energy consumption. The energy box verifies whether the demanded transaction has been carried out based upon at least one test, the test depending on at least one measured energy consumption. If the demanded transaction has been carried out, the energy box sends to a remote server a transaction response.

  • Publication number: 20140189799
    Abstract: Enhanced security for limited access through multi-factor authorization to cloud computing resources. The enhanced security is obtained by utilizing a personal security device to perform certain security operations as part of an authorization protocol such that an authorization grant is confirmed using two independent factors such as evidence of knowledge of a secret plus possession of a personal security device. The personal security device may also store an access token and perform cryptographic operations evidencing possession of the access token. Other systems and methods are disclosed.
