Pre-association security negotiation (PASN) configuration.
PASN configuration in IEEE 802.11az focuses on securing the ranging process before a device
fully associates with a Wi-Fi network. IEEE 802.11az supports various based AKMs as in
AKM_*
for PASN and cipher as in CIPHER_*
. Password is also another input to
some base AKMs.
Once PASN is initiated, the AP and the client device exchange messages to authenticate each other and establish security keys. This process ensures that only authorized devices can participate in ranging.
After successful PASN authentication, ranging operations are performed using the established secure channel. This protects the ranging measurements from eavesdropping and tampering.
The keys derived during the PASN process are used to protect the LTFs exchanged during ranging. This ensures that the LTFs are encrypted and authenticated, preventing unauthorized access and manipulation.

Fields
Public methods
describeContents
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(android.os.Parcel, int)
,
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
equals
public boolean equals (Object o)
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation
on non-null object references:
- It is reflexive: for any non-null reference value
x
,x.equals(x)
should returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
Parameters | |
---|---|
o |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getBaseAkms
public int getBaseAkms ()
Return base AKMs (Authentication and Key Management).
Returns | |
---|---|
int |
Value is either 0 or a combination of AKM_NONE , AKM_PASN , AKM_SAE , AKM_FT_EAP_SHA256 , AKM_FT_PSK_SHA256 , AKM_FT_EAP_SHA384 , AKM_FT_PSK_SHA384 , AKM_FILS_EAP_SHA256 , and AKM_FILS_EAP_SHA384 |
getCiphers
public int getCiphers ()
Return pairwise ciphers.
Returns | |
---|---|
int |
Value is either 0 or a combination of CIPHER_NONE , CIPHER_CCMP_128 , CIPHER_CCMP_256 , CIPHER_GCMP_128 , and CIPHER_GCMP_256 |
getPassword
public String getPassword ()
Get password used by base AKM. If null, password is retrieved from the saved network
profile for the PASN authentication. See getWifiSsid()
on retrieving saved
network profile.
Returns | |
---|---|
String |
getWifiSsid
public WifiSsid getWifiSsid ()
Get Wifi SSID which is used to retrieve saved network profile if getPassword()
is null. If Wifi SSID and password are not set and there is no saved profile corresponding to
the responder, unauthenticated PASN will be used if RangingRequest.getSecurityMode()
allows. See SECURITY_MODE_*
for more details.
Returns | |
---|---|
WifiSsid |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap
.
The general contract of hashCode
is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals
method, then calling thehashCode
method on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
equals
method, then calling thehashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns | |
---|---|
int |
a hash code value for this object. |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel : This value cannot be null . |
flags |
int : Additional flags about how the object should be written.
May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
