  • Patent number: 9698975
    Abstract: There is provided a method and apparatus for resetting a password for a device or managing the device, the device having an encryption perimeter. A device shares a public/private key pair with a server, the public key being on the device and the private key being on the server. An intermediate value is encrypted on the mobile device using the public key. If the password is lost or the device needs to be managed, the server can request the encrypted intermediate value, decrypt it, and send the decrypted value to the mobile device which may then resume operations. A new password may be provided by the server or the user may set a new password once the encryption key is recreated from the decrypted intermediate value.

  • Publication number: 20160373452
    Abstract: Some aspects of what is described here relate to managing the use of network resources on a mobile device. User input received at the device indicates whether to allow an application associated with a first perimeter on the device to access a network resource associated with a second perimeter on the device. For example, in some instances user input may indicate whether to allow data from applications associated with a personal perimeter on the device to be transmitted over an enterprise communication system. When outbound data associated with the first perimeter are received, the device determines, according to the indication from the user input, whether to route the outbound data to the network resource associated with the second perimeter.

  • Patent number: 9525999
    Abstract: A method for securely transferring a service from a first mobile device to a second mobile device, the service being associated with a server configured for facilitating provisioning of services to mobile devices over a wireless communications network. The method includes generating in the first mobile device a shared key, the shared key being generated using a master key unique to the server and to the first mobile device, the master key being accessible by the server and by the first mobile device; and sending said shared key from the first mobile device to the second mobile device using an alternate communication mechanism independent from the server.

  • Publication number: 20160337862
    Abstract: In some implementations, a method includes receiving, from a user of a first device, a request to enable access, through a second device, to a server resource account of an enterprise. The first device includes a first enterprise perimeter including an internal resource and a first enterprise identifier and configured to prevent external resources from accessing the internal resource. A request is wirelessly transmit, to the second device, to the second device for a second enterprise identifier assigned to a second enterprise perimeter included in the second device. Whether to grant access to the internal resource is determined based on a first enterprise identifier assigned to the first device and a second enterprise identifier assigned to the second device.

  • Publication number: 20160314310
    Abstract: A computing device and a method for a computing device to control access to data stored on a data store of the device. An access component of the device having control over access to the data. The access component being operative to receive a request for data from a requesting component, identify an assigned access domain of the requesting component and an assigned data domain of the requested data and determine whether the requesting component is authorized to access the data by comparing the assigned access domain and the data domain with permissions specified in a security policy. If the assigned access domain is authorized to access the data domain, the access component may provide access to the requested data.

  • Patent number: 9479339
    Abstract: In one illustrative scenario, a mobile device receives configuration information which includes information for use in constructing a request message for obtaining a digital certificate from a certificate authority (CA). After receipt of the configuration information, the mobile device constructs the request message for the digital certificate and causes it to be sent to a host server of a communication network. In response, the host server requests and obtains the digital certificate from the CA on behalf of the mobile device, and thereafter “pushes” the received digital certificate to the mobile device. The mobile device receives the digital certificate and stores it for use in subsequent communications. The host server may be part of a local area network (LAN) which includes a wireless LAN (WLAN) adapted to authenticate the mobile device based on the digital certificate, so that the mobile device may obtain access to the WLAN.

  • Patent number: 9479928
    Abstract: Often, for reasons of wireless bandwidth conservation, incomplete messages are provided to wireless messaging devices. Employing cryptography, for secrecy or authentication purposes, when including a received message that has been incompletely received can lead to lack of context on the receiver's end. By automatically obtaining the entirety of the message to be included, an outgoing message that includes the received message can be processed in a manner that securely and accurately represents the intended outgoing message. Alternatively, a server can assemble a composite message from a new message and an original message and, in cooperation with a wireless messaging device, encrypt and sign the composite message. Conveniently, security considerations are maintained even in view of bandwidth optimization measures.

  • Patent number: 9384342
    Abstract: Methods and devices for providing a warning associated with credentials to be stored in a credential store on a computing device are disclosed herein. In one broad aspect, the method comprises receiving a request to store, in the credential store, at least one credential for a specified service, determining whether a secure connection between the computing device and the specified service is available, associating the specified service with a level of security based on at least one of an availability of the secure connection or one or more properties of the secure connection, and providing a warning in response to determining that at least one credential stored in the credential store corresponds to the at least one credential for the specified service and is for a service that is associated with a level of security different from the level of security with which the specified service is associated.

  • Patent number: 9294470
    Abstract: Plural modes of operation may be established on a mobile device. Specific modes of operation of the mobile device may be associated with specific spaces in memory. By associating the existing certificate store structure and key store structure with a mode of operation, certificates and keys can be assigned to one space among plural spaces. Furthermore, management (viewing/importation/deletion) of certificates associated with specific modes of operation may be controlled based on the presence or absence of a mobile device administration server and the status (enabled/disabled) of an IT policy.
