Vivo Watch
From Wiki-IoT
Revision as of 08:01, 27 September 2025 by 20222819 Baitao Wang (talk | contribs) (The vivo Watch has no known hardware tampering, vulnerabilities, or targeted attacks. However, it has security limitations: rare updatability, partial system authentication, potentially obsolete encryption, and basic user authentication with no brute-force protection, constraining its overall security.)

|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Known hardware tampering | None | [2] | No public cases of hardware tampering due to consumer-oriented design. |
| Known vulnerabilities | None | [3] | No vulnerabilities related to vivo Watch recorded in NVD as of Sep 2025. |
| Prior attacks | None | [4] | No public targeted attacks on vivo Watch have been reported. |
| Updatability | Rare | [5] | Only basic function updates supported; system maintenance ceased after 2023. |

| System | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Authentication with other systems | Partial | [6] | Only supports Bluetooth pairing with vivo smartphones; no cross-brand authentication. |
| Communications | Encrypted with obselete encryption | [7] | Data transmission is protected by BLE encryption. |
| Storage | Encrypted with obselete encryption | [8] | Health data (e.g., heart rate, sleep) is unencrypted; relies on phone-side encryption. |
| Category score | 2 | ||
| User Authentication | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Account management | Basic | [9] | Basic account management is available primarily through the companion vivo Health app for pairing and basic settings. |
| Authentication | Basic | [10] | Authentication for the vivo Watch relies on basic Bluetooth pairing with a trusted vivo device, with no advanced multi-factor authentication. |
| Brute-force protection | Absent | [11] | There are no dedicated mechanisms (e.g., account lockout after multiple failed attempts) for brute-force protection on the vivo Watch itself. |
| Event logging | Absent | [12] | The vivo Watch does not have built-in capabilities for logging access or usage events in a detailed manner. |
| Passwords | Require change after setup | [13] | The vivo Watch relies on Bluetooth pairing with a vivo device (which may have password protection) rather than having its own standalone password requirements. |
