The implementation applies the following algorithm when evaluating a request for ac-
cess:
Request for Access Algorithm
Use Domain Mechanism (DM) to evaluate access to the method
if access is forbidden according to DM
Access Denied
else /* Access Granted according to DM, check ACP now */
if PKCS#15 is present
if ACIF link in DODF is present, then
if ACIF is found, then
lated to the entire SE
sions
ACLs are empty */
endif /* for ACIF */
Access Denied /* ACP link exists, but no applicable ACIF is found */
else /* No ACP */
Access Granted
endif
else /* No PKCS#15 */
Access Granted
endif
endif
If any errors in ACP or PKCS#15 (U)SIM structure is found during the evaluation al-
gorithm
execution access is denied.
The algorithm can be implemented in many different ways. The most efficient one
DRAFT - Subject to Change
loop for ACIE
if either ACIE contains AID for the target app or ACIE re-
get corresponding ACF to evaluate access permis-
if ACL is present
get ACE and evaluate access to the method
else
Access Granted /* ACL is missing */
endif
endif
endloop
Access Denied /* either no ACIE element is found or all found
