20110145585 | SYSTEM AND METHOD FOR PROVIDING CREDENTIALS - A method and system is operable to provide credentials by generating a first credential that conforms to a first specified format. A second credential conforming to a second specified format is included in the first credential so that the second credential may be distributed through the cryptosystem using the first specified format. The credential may be a digital certificate. | 06-16-2011 |
20120089847 | METHOD OF OBTAINING AUTHORIZATION FOR ACCESSING A SERVICE - Methods and devices for obtaining authorization for a requestor to access a service are provided. In accordance with one embodiment, there is provided a method comprising receiving a requestor request for access to a service; sending an authorization request to one or more mobile devices associated with one or more authorizers on a first approval list; receiving an authorization response from the one or more mobile devices associated with the one or more authorizers on the first approval list; determining whether a predetermined level of authorization is received; and when the predetermined level of authorization is received, authorizing access to the service. | 04-12-2012 |
20120239777 | SECURE FINANCIAL TRANSACTIONS - A method of securely communicating a message for a financial transaction from a first correspondent to one or more recipients. The method comprises dividing the message into at least two portions. Each portion is intended for a recipient. Each portion intended for receipt by one of the recipients is encrypted with that recipient's public key. The message is signed and transmitted to one of the recipients to enable the recipient to verify the message and further transmit the message to a further recipient. | 09-20-2012 |
20130046976 | System and Method for Accessing Private Networks - A system and method are provided for using a mobile device to authenticate access to a private network. The mobile device may operate to receive a challenge from an authentication server, the challenge having being generated according to a request to access a private network; obtain a private value; use the private value, the challenge, and a private key to generate a response to the challenge; and send the response to the authentication server. An authentication server may operate to generate a challenge; send the challenge to a mobile device; receive a response from the mobile device, the response having been generated by the mobile device using a private value, the challenge, and a private key; verify the response; and confirm verification of the response with a VPN gateway to permit a computing device to access a private network. | 02-21-2013 |
20130124870 | CRYPTOGRAPHIC DOCUMENT PROCESSING IN A NETWORK - Data received over a network is processed by a server. The processing includes determining identity information corresponding to an identity associated with a document represented by document data received over an input port of the server from a sender. At the server, a private key is computed based on: a master private key, and the identity information. At the server digital information is computed based at least in part on the document data using the computed private key. The digital information is stored in a storage medium accessible to the server in association with the identify information. | 05-16-2013 |
20130343542 | METHODS AND DEVICES FOR ESTABLISHING TRUST ON FIRST USE FOR CLOSE PROXIMITY COMMUNICATIONS - Methods and devices for establishing trust on first use for close proximity communications are disclosed. An example method includes receiving a public key from a device via a close proximity communications connection, obtaining, via a user interface, an indication that the device is trusted, and storing at least one of the public key or an identifier for the device. | 12-26-2013 |

20140137197 | DATA INTEGRITY FOR PROXIMITY-BASED COMMUNICATION - Methods, systems, and computer programs for trusted communication among mobile devices are described. In some aspects, an authentication value is generated at a first mobile device based on a message and a shared secret value stored on the first mobile device. In response to detecting proximity of a second mobile device, the message and the authentication value are wirelessly transmitted from the first mobile device to the second mobile device. In some implementations, the message and the authentication value can be wirelessly transmitted by a proximity-activated wireless interface, such as, for example, a Near Field Communication (NFC) interface. | 05-15-2014 |
20140141750 | DATA INTEGRITY FOR PROXIMITY-BASED COMMUNICATION - Methods, systems, and computer programs for trusted communication among mobile devices are described. In some aspects, information is wirelessly transmitted from a first mobile device to a second mobile device. The information permits the second mobile device to detect proximity of the first mobile device. In some implementations, the information can be wirelessly transmitted by a proximity-activated wireless interface, such as, for example, a Near Field Communication (NFC) interface. In response to the information, the first mobile device receives a message and a first authentication value wirelessly transmitted from the second mobile device to the first mobile device. A second authentication value is generated at the first mobile device based on the message and the shared secret value. Integrity of the message is verified based on comparing the first authentication value and the second authentication value. | 05-22-2014 |
20140181955 | TWO FACTOR AUTHENTICATION USING NEAR FIELD COMMUNICATIONS - There is provided a method and apparatus for communications using short range communications such as Near Field Communications (NFC). A mobile device comprising an NFC subsystem provides a dynamic credential for use to login to a network requiring two factor authentication. A terminal used for logging in to the network is associated with an NFC reader, and bringing the NFC device in proximity to the NFC reader provides the terminal with the dynamic credential required for two factor authentication. | 06-26-2014 |
