What happened
The feed contains multiple wireless-communications and coding research preprints with immediate relevance to authentication and physical-layer security. Key items: (1) “Frozen-Tag-Based PLA” — proposes inserting a polar-code–style frozen tag (raw tag as frozen bits, anchor info as information bits) to improve robustness against unintended user interference and to conceal raw tags from eavesdroppers; (2) “Tag-based PLA Against Message Interference” — proposes a Tag-Based Challenge-Response (TBCR) scheme and a Series Cancellation Authentication (SCA) scheme to avoid tag estimation via message-de
