Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of document should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or
www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of
any claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC
had not received notice of (a) patent(s) which may be required to implement this document. However,
implementers are cautioned that this may not represent the latest information, which may be obtained
from the patent database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall
not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 17, Cards and security devices for personal identification.
A list of all parts in the ISO/IEC 7816 series can be found on the ISO and IEC websites.

Part 4:
Organization, security and commands for interchange
AMENDMENT 1: Support of multiple logical security devices

Clause 3
Add the following term and definition at the end of Clause 3:
3.68
logical security device
collection of resources of the physical ICC, build for a logical view as a virtual ICC

Table 4
Add the following new entry after MANAGE DATA entry:
MANAGE LOGICAL SECURITY DEVICE
'7C' 11.9
Table 5
Add the following new entry after MANAGE CHANNEL entry:
MANAGE LOGICAL SECURITY DEVICE
'7C' 11.9
Clause 7
Add the following subclauses after the last subclause in Clause 7:
7.5  Multiple logical security device
7.5.1  Concept of logical security devices
Logical resources are the collection of resources of the physical ICC, described in Clause 5 to Clause 11
(except 7.5), assigned to the logical security device as a virtual ICC on the physical ICC. This collection
contains, e.g. the set of data structures with its own security architecture, security attributes and
security status, its own logical channels and a set of commands for interchange. An ICC supporting
logical security device offers at least the basic logical security device. Multiple logical security devices
may exist in parallel on one physical ICC. Each logical security device is identified by its logical security
device number.
NOTE 1 The assignment of logical resources to a logical security device in the opening process is
implementation dependent and can use configuration data on the physical ICC, addressed by the logical security
device number. This can also apply in particular for the security conditions to be fulfilled for opening a new
logical security device.
