  • Patent number: 8191150
    Abstract: The present invention relates to a novel method for handling applications in a device by associating an application signed by a domain certificate to a pre-defined entity in a device, said device comprising: a module reader for reading subscriber identity, a virtual machine for running at least one application, a memory containing a root certificate, the method comprising: using a data set for aggregating a sub set of data, modifying portion of said data set such that said portion includes reference to said entity. The invention also relates to a device for implementing the method.

  • Patent number: 7877087
    Abstract: Operating a mobile terminal may include providing a list in memory of the mobile terminal with the list including at least one identification of a communications device remote from the mobile terminal. An update for the list may be received from outside the mobile terminal over a wireless link, and the list may be automatically updated in the memory of the mobile terminal after receiving the update from outside the mobile terminal. Communications may then be moderated based on the list in the memory. Related systems and computer program products are also discussed.

  • Publication number: 20100153667
    Abstract: A method for utilizing a secure memory in an electronic device for launching/running an application may include copying at least a portion of the application into the secure memory of the electronic device, and permanently storing the at least one portion of the application in the secure memory. The permanent storage of the at least one portion of the application in the secure memory obviates the need re-copy the application to the secure memory if/when the application is subsequently executed by the electronic device.

  • Publication number: 20090193265
    Abstract: An apparatus and method of protecting the integrity of a database is provided. Protection of the database is implemented by randomly selecting part of the database that is to be authenticated, the part of the database being less than the entire database to be authenticated. Then, only the selected part of the database is processed through a security function to generate a representation of authentication of the database for comparison with another representation of authentication of the database. Based on a comparison of the representation of authentication and the another representation of authentication, it is determined if integrity of the database has been maintained.

  • Publication number: 20090193026
    Abstract: An apparatus and method for providing replay protection integrity protection of a database accessible by an electronic device is provided, wherein the database is capable of protecting a plurality of records. When at least one protected record in the database is modified in an authorized manner, a record tag corresponding to the at least one protected record is stored in the database, and the at least one protected record and the corresponding record tag are copied into a cache. Upon retrieval of the at least one protected record from the database, the copied record tag stored in the cache is compared with the corresponding record tag stored in the database. Use of the retrieved protected record is inhibited if the copied record tag stored in the cache does not correspond to the record tag stored in the database, and otherwise use of the retrieved protected record is enabled.

  • Publication number: 20080189695
    Abstract: A method and an electronic device for updating data instructions of an electronic apparatus (1) based on updating data. The method comprises acquiring updating data for updating of data instructions, meta data associated with the updating data, and at least one security mechanism associated with at least one of the updating data and the meta data. Then, it is verified by means of the security mechanism whether any of the updating data and the meta data has been unauthorizedly altered. A method and an arrangement for generating the updating data and the meta data are also disclosed.
