IEEE 802.15 Proposal for Removal of Security Part from MAC
This document proposes the removal of the security part from the IEEE 802.15 MAC proposal to potentially enhance efficiency and speed of data transactions within wireless personal area networks. The suggestion is based on the notion that security functions could be implemented at an upper layer, akin to how NFC security is handled separately from the communication protocol layer, thus streamlining the process. The proposal allows for flexibility in future amendments to incorporate security functions if necessary.

Purpose: To modify the current TG3e draft document. Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributors acknowledge and accept that this contribution becomes the property of IEEE and may be made publicly available by P802.15. Submission Slide 1 Kondou (Sony)
<Oct. 2015> doc.: IEEE 802.15-15-0801-00-003e Comment on TG3e proposal Remove security part in 7.2.x and 7.3.x. Reason less demand from task group members Protection in an upper layer may be sufficient. Example: Near Field Communication (NFC) - Security function in NFC is realized above the communication protocol layer. 4-way handshake to exchange security information takes a long time before transaction of data. Security function can be employed in an future amendment by utilizing one of reserved bits as a indicator of security transaction, even if the implementation of security in the MAC layer is required.
