Participants, Patents, and Duty to InformAll participants in this meeting have certain obligations under the IEEE-SA Patent Policy. Participants:

“Shall inform the IEEE (or cause the IEEE to be informed)” of the identity of each “holder of any potential Essential Patent Claims of which they are personally aware” if the claims are owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents

“Personal awareness” means that the participant “is personally aware that the holder may have a potential Essential Patent Claim,” even if the participant is not personally aware of the specific patents or patent claims

“Should inform the IEEE (or cause the IEEE to be informed)” of the identity of “any other holders of such potential Essential Patent Claims” (that is, third parties that are not affiliated with the participant, with the participant’s employer, or with anyone else that the participant is from or otherwise represents)

The above does not apply if the patent claim is already the subject of an Accepted Letter of Assurance that applies to the proposed standard(s) under consideration by this group

Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2 Early identification of holders of potential Essential Patent Claims is strongly

encouraged No duty to perform a patent search

Don’t discuss the interpretation, validity, or essentiality of patents/patent claims.

Don’t discuss specific license rates, terms, or conditions. Relative costs, including licensing costs of essential patent claims, of different technical

approaches may be discussed in standards development meetings. Technical considerations remain primary focus

Don’t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets.

Don’t discuss the status or substance of ongoing or threatened litigation. Don’t be silent if inappropriate topics are discussed … do formally object.

Straw poll (MLME )

• Motivation – The current MLME-SCAN.confirm reports the status of the

discovery at the very end of the discovery operation. The immediate reporting of the discovered networks is done in most current implementations. The immediate reporting speeds up information passing from the MAC-layer.

• Concept – The MLME-SCAN.confirm primitive shall be invoked to report

every found BSS during the scan procedure.

Straw poll (FILS capability indication)

• Motivation – Without indication which STAs are FILS capable, the scanning

STAs or responding STAs cannot detect other FILS capable STAs. The detection of the FILS capable STAs is needed to the use of FILS specific scanning logic.

• Concept– If applicable, Probe Request, Probe Response and Beacon should

indicate FILS capability.

Straw poll (Probe Request )

• Motivation – The requesting STA may have information of the STAs which it

already knows or from which it is not interested to receive Probe Request. The knowledge may be obtained during the time when the STA was looking for TXOP to transmit the Probe Request, or from the previous Probe Request.

• Concept– The probe request may restrict responses by indicating APs that

should or should not respond

• Strawpoll • Do you agree on above mentioned concept? • Yes: 19 No: 0 Abstain: 3

Straw poll (Prove request )

• Motivation – Without knowledge of the time when the Probe Request transmitter is

available to receive Probe Responses, the individually addressed Probe Responses may be unnecessarily (re)transmitted.

– In congested BSS, it may be difficult and power consuming for the requesting STA to transmit a frame to indicate that the STA is no longer available to receive Probe Responses.

• Concept– The transmitter of the Probe Request frame may indicate the time when it is

available to receive Probe Response frames.

• Strawpoll • Do you agree on above mentioned concept? • Yes: 17 No: 0 Abstain: 5

Straw poll (Cancelling Probe Responses transmission )

• Motivation – The general knowledge when the STA is receiving at the

channel reduces transmissions of unnecessary Probe Responses. – The requesting STA may indicate to be available to receive Probe

Responses for a certain time period. If the channel is idle, the device may need unnecessarily use its battery to be available at the channel.

• Concept– Responses to Probe Request may be cancelled by requesting STA

• Strawpoll • Do you agree on above mentioned concept? • Yes: 13 No: 2 Abstain: 8

Straw poll (Probe Response )

• Motivation – The broadcast addressed Probe Response may be

received by many STAs. The broadcast addressed Probe Responses are not acknowledged and thus not retransmitted. This reduces traffic load in congested situations.

• Concept– The Probe Response frame may be transmitted to an individual or

broadcast address.

• Strawpoll • Do you agree on above mentioned concept? • Yes: 16 No: 0 Abstain: 7

Submission

Straw poll

• Motivation– The BSS information on other channels helps to select the channel

that is scanned next. More information of the BSSs provides more knowledge to scanning STA. For instance, if the STA transmits Probe Request to individual address, it may collect information of many APs with reduced amount of Probe Responses.

• Concept– The Probe Response may contain information of other than

responding AP (Comprehensive response).

• Strawpoll • Do you agree on above mentioned concept? • Yes: 14 No: 1 Abstain: 8

Submission

Straw poll

• Motivation– The Beacon frame needs to be transmitted at TBTT to provide information

of the availability of the AP and to indicate availability of the buffered frames for power saving STAs.

– The amount of unnecessary copies of the Probe Response frames should be minimized. The smaller amount of transmitted frames reduces traffic load and speeds up the discovery operation.

• Concept– AP may transmit a Beacon frame instead of Probe Response frame if the

TBTT occurs within short time interval

• Straw poll • Do you agree on above mentioned concept? • Yes: 13 No: 1 Abstain: 6

4. Both devices do share a weak secret key.

5. Both devices do share a secret key.•  • Strawpoll #1: Scenario #1 should be included, where devices are STA and AP

respectively and third party is AS. Y/N/A = 20/0/3.• Strawpoll #2: Scenario #2 should be included, where devices are STA and AP

respectively and where AS may provide authorization service. Y/N/A = 7/2/14.

• Authenticated key agreement schemes generally include the following security properties:

1. Key establishment

2. Key Agreement

3. Implicit key authentication

4. Explicit key authentication

5. No unilateral key control

6. Forward secrecy

7. Entity authentication

8. Unknown Key Share Resilience•  • Strawpoll #3: This should include all properties (mutually), except #6. Y/N/A =

2/1/20.• Strawpoll #4: This should include all properties (mutually), including #6. Y/N/A =

4/3/20.

• Further considerations:

1. Schemes shall be demonstrably free of known security weaknesses (burden on proposers)

2. Schemes shall be well-studied by the cryptographic community

3. Schemes should be standardized via internationally accepted cryptographic standards (NIST/FIPS series, IETF)

 • Strawpoll #6: Schemes should satisfy #1, where the onus is on

proposals/proposers to provide solid evidence. Y/N/A = 8/1/9.• Strawpoll #7: Schemes should satisfy #2, where the onus is on

proposals/proposers to provide solid evidence. Y/N/A = 6/1/14.• Strawpoll #8: Schemes should satisfy #3, where the onus is on

proposals/proposers to provide solid evidence. Y/N/A = 10/1/9.

Straw poll (Security)

• Joining protocols would involve authorization, where:

1. Authorization of the STA may be provided by the third party AS;

2. The third party providing authorization may be different from the third party potentially providing authentication support.

• Strawpoll #9: Scenario #1 should be supported. Y/N/A = 9/0/7.

• Strawpoll #10: Scenario #2 should be supported. Y/N/A = 2/4/14
