The formal approval successfully brought to a close more than two years of effort, and provided the infrastructure for trusted Web site identity on the Internet.
Dedicated file DF Elementary file EF The logical organization of data in a card consists of following structural hierachy of dedicated files: The DF at the root is called the master file MF. The MF is mandatory. The other DFs are optional. The following two types of EFs are defined: Figure 1 illustrates an example of the logical file organization in a card.
Referencing by file identifier - Any file may be referenced by a file identifier coded on 2 bytes. In order to select unambiguously any file by its identifier, all EFs and DFs immediately under a given DF shall have different file identifiers. Referencing by path - Any file may be referenced by a path concatentation of file identifiers.
The path begins with the identifier of the MF or of the current DF and ends with the identifier of the Extended response itself. Between those two identifiers, the path consists of the identifiers of the successive parent DFs if any.
The order of the file Extended response is always in the direction parent to child. The path allows an unambiguous selection af any file from the MF or from the current DF.
Referencing by short EF identifier - Any EF may be referenced by a short EF identifier coded on 5 bits valued in the range from 1 to Short EF identifiers connot be used in a path or as a file identifier e. In order to select unambiguously by DF name e.
The following structures of EFs are defined: Transparent structure - The EF is seen at the interface as a sequence of data units. Record structure - The EF is seen at the interface as a sequence of individually identifiable records.
The following attributes are defined for EFs structured in records: Size of the records: The card shall support at least one of the following four methods for structuring EFs: Linear EF with record of fixed size. Linear file with records of variable size.
Cyclic EF with records of fixed size. Figure 2 shows those for EF structures.
Data is considered to be stored in a single continuous sequence of records within an EF of record structure or of data units within an EF of transparent structure.
Reference to a record or to a data unit outside an EF is an error. Data referencing method, record numbering method and data unit size are EF-dependent features. When the card provides indications in several places, the indication valid for a given EF is the closest one to that EF within the path from the MF to that EF.
Referencing by record identifier shall induce the management of a record pointer. Referencing by record number shall not affect the record pointer.
Referencing by record identifier - Each record identifier is provided by an application. Within an EF of record structure, records may have the same record identifier, in which case data contained in the records may be used for discriminating between them.
Each time a reference is made with a record identifier, an indication shall specify the logical position of the target record the first or last occurrence, the next or previous occurrence relative to the record pointer: Within each EF of linear structure, the logical positions shall be sequentially assigned when writing or appending i.
Therefore the first created record is in the first logical position. Within each EF of cyclic structure, the logical positions shall be sequentially assigned in the opposite order, i. The following additional rules are defined for linear structures and for cyclic structures: The first occurrence shall be the record with the specified identifier and in the first logical position; the last occurrence shall be the record with the specified identifier and in the last logical position.
When there is no current record, the next occurrence shall be equivalent to the first occurrence.MAHADISCOM - Maharashtra State Electricity Distribution Co. Ltd. supplies electricity to a staggering crore consumers across the categories all over Maharashtra excluding the island city of Mumbai.
