ANSI ISO IEC 7816-9-2000 pdf download dentification cards — Integrated circuit(s) cards with contacts — Part 9: Additional interindustry commands and security attributes
6 Life cycle status
6.1 Definition and purpose The card, files and other objects in the card each have a life cycle, in principle as shown in Annex A. States in the life cycle may be manipulated by commands. This part of ISO/IEC 7816 defines such commands.
Annex A gives a list of these commands. A life cycle status (LCS) may be associated with files as one of the attributes. It may also be associated with other resources in the card. To support flexible management of the life cycle as an attribute, a number of life cycle states have been identified, which are defined in this clause. This clause also defines an encoding of the states in the life cycle. This clause defines a coding of the LCS that allows the card to identify the states.
In addition it allows the application to define additional life cycle states. Changes are controlled by the card and may be performed in a pre-defined order, reflecting reversible or irreversible changes in state.
6.2 Principles of use A card may support a LCS attribute associated with files and, possibly, other objects in the card to indicate the different logical security states of the use of these objects.
Commands may set the value of the LCS attribute when they execure. However the card shall maintain the integrity of this value in accordance with this part of ISO/IEC 7816. If supported, the current LCS of an object, as expressed by its value, shall be used by the card, possibly in combination with additional security attributes, to determine whether a requested operation with the object is in accordance with the specified security policy.
This standard defines 4 primary states of the life cycle (see 6.3 and Annex A) in the following order:
creation state;
initialisation state;
operational state;
termination state.
Transitions between the primary states of the life cycle are irreversible and occur in only a top-to-bottom direction.
Each primary state may have reversible secondary states.
6.3 Life cycle rules
The use of objects is governed by the current LCS according to the following rules:
when an object is in the creation state, any security attributes for that object shall not apply;
when an object is in the initialisation state, then security attributes specific to this state may apply;
when an object is in the operational state, then the associated security attributes shall apply;
when an object is in the termination state, then it shall not allow a modification of its value but it may be used as specified by its associated security attributes e.g. it may be deleted.
