Request - arXiv endorsement needed for cs.CR (Cryptography and Security)
Hi everyone,
I am preparing to submit my paper to arXiv under the cs.CR (Cryptography and Security) category, and I am looking for a registered endorser for this section.
My paper, titled "Exploiting Fixed-Code RF Protocols in Micro-Mobility: A Case Study of the Yadea T5 Keyless Entry System (CVE-2025-70994)" , presents a comprehensive security analysis of the EV1527 fixed-code RF protocol. It details a methodology using low-cost SDR hardware to passively intercept and synthesize high-sensitivity vehicle commands due to a lack of rolling code mechanisms.
Here is the abstract:
"The rapid adoption of micro mobility vehicles, such as electric bicycles and scooters has driven manufacturers to replace or combine traditional mechanical locks with electronic keyless entry systems. however, to reduce manufacturing costs, many of these systems rely on legacy radio frequency (RF) integrated circuits that lack modern cryptographic protections. this paper presents a comprehensive security analysis of the EV1527 fixed-code RF protocol as implemented in the YADEA T5 electric bicycle platform. we demonstrate a critical weak authentication vulnerability (CWE-1390) [1], officially designated as CVE-2025-70994. because the EV1527 protocol utilizes a static 20-bit device address and lacks rolling code mechanisms, it is highly susceptible to RF replay attacks. utilizing low-cost, readily available software-defined radio (SDR) and microcontroller hardware, we outline a methodology to passively intercept, decode and synthesize high-sensitivity vehicle commands, such as ignition, without authorization. the vulnerability yields a CVSS v3.1 base score of 7.3 (High). finally, this paper proposes immediate physical security mitigation for current vehicle owners and long-term cryptographic protocol upgrades for hardware manufacturers to secure the next generation of micro mobility platforms."
If you are an eligible endorser for cs.CR and would be willing to read my draft and potentially endorse my submission, please send me a Direct Message or comment below and I will reach out. I can provide the full PDF for your review along with the endorsement code.
Thank you for your time and help!
