O.CLON

The TOE functionality needs to be protected from

cloning.

The TOE must include means to prevent an attacker from

reproducing the smartcard functionality. Most of these

techniques require a prior reverse engineering of parts of

the device to understand its architecture and its security

functions.

O.OPERATE

The TOE must ensure the continued correct operation

of its security functions.

The TOE must include protection against the use of stolen

silicon samples or products that would ease an attacker

gaining fraudulous access to the smartcard system.

The TOE must also provide mechanisms to avoid the

unauthorized modification of the security functions or

software and data, by using the device test commands for

instance, or by using uncontrolled/unauthentified software

access to memories.

The TOE must prevent its operation outside the normal

operating conditions where reliability and secure operation

has not been proven or tested. This is to prevent errors. The

environmental conditions may include voltage, clock

frequency, temperature, or external energy fields

O.FLAW

The TOE must not contain flaws in design,

implementation or operation.

The TOE design must include protection against

modification of its security mechanisms (for example

detectors or memory protections) that would lead to bypass

or reduce their integrity, and therefore open security holes

that could be used to access embedded software and data.

The TOE design must also provide protection against

modification of its embedded software that would lead to

bypass or reduce the integrity of some software controlled

security mechanisms (for example memory areas

definition), and therefore open security holes that could be

used to access embedded software and data.

O.DIS_MECHANISM

The TOE shall ensure that the hardware security

mechanisms are protected against unauthorized

disclosure.

The TOE must be designed and fabricated so that it requires

a high combination of complex equipment, knowledge, skill

and time to derive detailed designed information or other

information which could be used to compromise security

through physical attacks.
