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. ## Claims ### Claim 1 A method for updating data instructions of an electronic apparatus (1) based on updating data, comprising: acquiring updating data for updating data instructions; acquiring meta data associated with the updating data; acquiring at least one security mechanism associated with at least one of the updating data and the meta data; and verifying, by means of the security mechanism, whether any of the updating data and the meta data has been unauthorizedly altered. ### Claim 2 (depends on 1) The method according to claim 1, further comprising, if it is verified any of the updating data and the meta data has not been unauthorizedly altered, the steps of: reading at least one updating criteria contained in the meta data; reading identification data stored in the electronic apparatus (1); and determining whether the identification data fulfills the updating criteria. ### Claim 3 (depends on 1, 2) The method according to claim 1 or 2, further comprising: transmitting a revocation status request to a revocation status center (145, 146); receiving a revocation status response from the revocation status center; and determining from the revocation status response whether the security mechanism is valid. ### Claim 4 The method according to any of the previous claims, comprising: executing the step of verifying in response to a request for updating the data instructions. ### Claim 5 The method according to any of the previous claims, comprising: storing the updating data at a storage location (12), which is not accessible without authorization. ### Claim 6 The method according to any of the previous claims, comprising: acquiring the updating data and the meta data from a common data file (100). ### Claim 7 (depends on 1, 2, 3, 4, 5) The method according to any of the claims 1 to 5, comprising: acquiring the updating data from a first data file (110) and the meta data from a second data file (120); acquiring a first identifier for identifying the updating data from the first data file; acquiring at least a second identifier for identifying updating data for which the meta data is applicable from the second data file; and determining whether the first identifier match any identifier acquired from the second data file. ### Claim 8 A method for generating updating data for updating data instructions of an electronic device, comprising: generating updating data for updating at least a portion of data instructions; generating meta data containing at least one updating criterion for the updating data; and attaching a security mechanism to at least one of the updating data and the meta data. ### Claim 9 (depends on 8) The method according to claim 8, comprising incorporating any of an operator ID, an electronic equipment identifier, a software version identifier, a software identifier, an electronic equipment type identifier, an electronic equipment model identifier, or a customization identifier, as the updating criterion. ### Claim 10 (depends on 8, 9) The method according to claim 8 or 9, comprising attaching revocation status data to at least one of the updating data and the meta data. ### Claim 11 (depends on 8, 9, 10) The method according to any of claims 8 to 10, comprising incorporating the updating data, the meta data and the security mechanism into a common data file (100). ### Claim 12 (depends on 8, 9, 10, 11) The method according to any of claims 8 to 11, comprising incorporating the updating data in a first data file (110) and the meta data in a second data file (120), and provide an identifier for identifying the updating data in each of the first and the second data file. ### Claim 13 An electronic device for updating data instructions of an electronic apparatus (1) based on updating data, comprising and updating unit (13) configured to: acquire updating data for updating data instructions; acquire meta data associated with the updating data; acquire at least one security mechanism associated with at least one of the updating data and the meta data; and verify, by means of the security mechanism, whether any of the updating data and the meta data has been unauthorizedly altered. ### Claim 14 (depends on 13) The electronic device according to claim 13, wherein the updating unit (13) is further configured to: read at least one updating criteria contained in the meta data; read identification data stored in the electronic apparatus (1); and determine whether the identification data fulfills the updating criteria. ### Claim 15 (depends on 13, 14) The electronic device according to claim 13 or 14, further comprising a verification unit (141) configured to: transmit a revocation status request to a revocation status center (145, 146); receive a revocation status response from the revocation status center; and determine from the revocation status response whether the security mechanism is valid. ### Claim 16 (depends on 13, 14, 15) The electronic device according to any of claims 13 to 15, wherein the updating unit (13) is configured to: acquire the updating data and the meta data from a common data file (100). ### Claim 17 (depends on 13, 14, 15) The electronic device according to any of claims 13 to 15, wherein the updating unit (13) is configured to: acquire the updating data from a first data file (110) and the meta data from a second data file (120); acquire a first identifier for identifying the updating data from the first data file; acquire at least a second identifier for identifying updating data for which the meta data is applicable from the second data file; and determine whether the first identifier match any identifier acquired from the second data file. ### Claim 18 An arrangement for generating updating data for updating data instructions of an electronic device (1), comprising: an updating data generator (151) operative to generate updating data for updating at least a portion of data instructions; a meta data generator operative to generate meta data containing at least one updating criterion for the updating data; and a security unit (153) operative to attach a security mechanism to at least one of the updating data and the meta data. ### Claim 19 (depends on 18) The arrangement according to claim 18, wherein the meta data generator (152) is operative to incorporate any of an operator ID, an electronic equipment identifier, a software version identifier, a software identifier, an electronic equipment type identifier, an electronic equipment model identifier, or a customization identifier, as the updating criterion. ### Claim 20 (depends on 18, 19) The arrangement according to any of claims 18 or 19, wherein the arrangement is operative to incorporate the updating data, the meta data and the security mechanism into a common data file (100). ### Claim 21 (depends on 18, 19) The arrangement according to any of claims 18 to 19, wherein the arrangement is operative to incorporate the updating data in a first data file (110) and the meta data in a second data file (120), and provide an identifier for identifying the updating data in each of the first and the second data file. ### Claim 22 (depends on 1, 2, 3, 4, 5, 6, 7) A computer program product comprising computer program code means for executing the method according to any of claims 1 to 7, when said computer program code means are run by an electronic device having computer capabilities. ### Claim 23 (depends on 8, 9, 10, 11, 12) A computer program product comprising computer program code means for executing the method according to any of claims 8 to 12, when said computer program code means are run by an electronic device having computer capabilities.
