AES-256 encryption! Battery-free NFC Smart Lock Secures Centralized Mailboxes

In the centralized mailbox scenarios of enterprises, schools, and government agencies, the security loopholes and management inefficiencies of traditional locks are becoming the “heart of the problem” of message delivery - key duplication risks, password leakage hazards, and battery failure leading to mail stranding ...... These problems not only affect work efficiency, but also may lead to the leakage of confidential documents. With AES-256 financial grade encryption technology and zero-battery design, the battery-free NFC smart lock creates a new security paradigm for centralized mailboxes, which is “crack-proof, maintenance-free and fully intelligent”.

The three major security blind spots of traditional mailbox locks, do you realize?

1. Mechanical lock copying crisis:

1. A law firm faced a customer trust crisis due to the copying of mailbox keys, which led to the early leakage of undisclosed legal documents;

2. Statistics show that the key duplication rate of traditional mechanical locks is as high as 30%, and the duplication records cannot be traced.

2. The encryption vulnerability of electronic locks:

1. Ordinary electronic locks use simple encryption algorithms, a college mailbox system has been violently broken due to passwords, student admission notices were maliciously tampered with;

2. Battery dependence leads to 15% of locks cannot be opened normally in low temperature environment, and complaints about mail delay in winter surged by 40%.

3. Chaotic state of authority management:

1. When many people share a key, it is impossible to trace the specific person who opened the lock, a government department had lost internal documents, the investigation took up to 2 months.

AES-256 encryption + battery-free design: redefining mailbox security standards

1. AES-256 financial-grade encryption: makes cracking a “mission impossible”

· Military-grade security barriers: Adopting the AES-256 encryption algorithm certified by the National Institute of Standards and Technology (NIST) of the United States, the key length is up to 256 bits, and violent decryption needs to consume 10^30 years of computation time, with a security that is 1,000 times more secure than that of traditional mechanical locks;

· dynamic key mechanism: each unlocking generates a unique dynamic key, together with the anti-middleman attack technology, completely eliminating the risk of signal interception, after the deployment of the headquarters of a bank, the mailbox system security audit score increased to 98 points (out of 100).

2. Battery-free reverse power supply: the ultimate zero-maintenance solution

· technical innovation: no need for built-in battery, reverse power supply through cell phone NFC function (single unlock consumes only 0.01mAh), support iPhone 7 and above /iOS 13+, Android NFC models, cell phone out of battery can be connected to the charging treasure temporary unlocking;

· cost subversion: the average annual maintenance cost of traditional electronic locks is $120/grip (battery replacement + faulty maintenance), while the 10-year operation and maintenance cost of battery-free smart locks tends to be close to zero, and the annual cost of a 500-person enterprise is more than 60,000 yuan.

3. NFC one-touch unlocking: 3 seconds to complete the identity verification

· operation is very simple: cell phone close to the lock surface can be unlocked, no need to carry a physical key or memorize the password, adapt to high-frequency use scenarios (such as the average daily opening of enterprise front desk mailbox 500 + times);

Strong compatibility: provide round cam lock, embedded square lock and other forms, compatible with 99% of the existing mailbox cabinet (thickness 15-50mm), 10 minutes to complete the replacement of the old lock, without the need to modify the cabinet structure.

4. IP66 protection + plastic housing: resistance to humid and dusty environments

· environmental adaptability: dustproof level 6 (completely blocking dust), waterproof level 6 (anti-high-pressure water gun wash), measured in 90% humidity, dust concentration 0.5mg/m³ environment for 3 years of continuous work without failure;

Signal optimization: exclusive ABS plastic shell (non-metallic material) to avoid signal interference, even if the mailbox cabinet is made of metal, the NFC signal penetration rate is still up to 98%, 4 times higher than the traditional metal lock.

Full-scene adaptation: mailbox security standardization from enterprise to government affairs

1. Centralized mailbox for enterprise front desk

· A technology company deploys round cam locks, administrators assign departmental mailbox permissions in real time via APP, departing employees' permissions are recovered in seconds, the efficiency of retrieving important contract documents is increased by 60%, and delays caused by key management errors are zeroed out.

2. Higher education students' mailboxes

· Tsinghua University Shenzhen Campus adopts embedded square locks to manage student mailboxes, supports “semester system privileges” (automatic opening/closing), and prevents tampering of acceptance letter information with AES-256 encryption, which increases student satisfaction from 72% to 95%.

3. Governmental important mailboxes

· A provincial government affairs center uses long cam locks, and all unlocking records are synchronized in real time to the supervisory system (including operator, time, and lock number), which meets the security requirements of Level 3 of the equal protection, improves the auditing efficiency by 80%, and realizes the full-process control and management of “unlocking is tracing”.

Customized service: let the mailbox lock become the double carrier of security and image

As an electronic lock factory, we provide full-link customization solutions:

· function customization: support “time slot authorization” (e.g. only weekdays 9:00-18:00 unlocking), “multi-level permissions” (distinguishing between administrators and ordinary users), “vibration Alarm” (illegal lock picking triggers APP push);

· Appearance design: 7 kinds of colors such as elegant black, silver gray, champagne gold, etc., laser engraving of enterprise LOGO or organization logo, to enhance the overall texture of mailbox area;

· package empowerment: customized manual (including security tips, administrator operation guide) is attached with the lock, and exclusive QR code can be printed on the lock body to guide users to download the management APP.

Conclusion: When mailbox security becomes a “moat” in the information age

At a time when information leakage incidents occur frequently, the security management of centralized mailboxes has long exceeded the “lock” itself and become an important line of defense for the credibility and data security of organizations. Battery-free NFC smart lock with AES-256 encryption as the shield and zero-maintenance design as the blade, to protect the delivery of each mail.
