Patents Related to Arnev Secure Cloud
Arnev has amassed a robust patent portfolio that protects its proprietary encryption methodology and privacy framework. The Arnev Secure Cloud (ASC) patents cover a multi‑layered architecture designed to protect data integrity, confidentiality, and privacy across the entire data pipeline.
- Device‑Level Encryption Engine – each device’s firmware incorporates a lightweight hardware accelerator that performs AES‑256 encryption on outbound packets before they leave the device. The accelerator shares a unique, per‑device key derived from an embedded elliptic‑curve keypair (ECC‑P256). This key is stored in a tamper‑resistant memory block (EEPROM with secure erase). On boot, the device performs a secure‑boot sequence that verifies the hash of the firmware image, ensuring that only authenticated code runs.
- Key‑Management Protocol (KMP) – a hierarchical approach where root keys are held within a Hardware Security Module (HSM) in the cloud. Each device holds a session key that is rotated every 24 hours via a Diffie–Hellman key exchange over TLS 1.3. The KMP is patented to allow dynamic key revocation and provisioning without device downtime.
- Homomorphic Encryption Layer – patents exist for performing certain arithmetic operations (addition, multiplication) on ciphertexts within the cloud without decryption, preserving privacy of aggregated data. This is used in the ASC to calculate global statistics (e.g., average device battery level) while keeping individual device telemetry hidden.
- Zero‑Knowledge Proof for Device Authentication – a patented protocol that allows a device to prove its authenticity to the cloud without revealing its secret key. This eliminates the need for storing secrets on the server and mitigates the risk of credential theft.
- End‑to‑End Encryption Flow – the ASC’s API gateway enforces TLS 1.3 with forward secrecy. All data payloads are wrapped in an authenticated encryption with associated data (AEAD) cipher, typically AES‑256 in Galois/Counter Mode (GCM). This ensures integrity and confidentiality from device to cloud and back.
- Secure Data Aggregation – when data is aggregated for analytics, the ASC employs a patented “Privacy‑Preserving Aggregation” (PPA) algorithm that masks individual contributions using randomization while preserving the ability to compute accurate aggregate statistics. This technique is especially critical for telehealth analytics where patient data must remain confidential.
- Encrypted Metadata Service – the ASC stores metadata (e.g., device location, firmware version) in a separate encrypted table. A separate encrypted keyset, stored in the HSM, is used to decrypt this metadata only on authorized administrative clients. This prevents exposure of sensitive device attributes.
- Replay‑Attack Mitigation – timestamps and nonces are embedded in each packet header. The ASC validates them against a sliding window stored in a cache. Any packet with a stale nonce triggers a rejection and is logged for forensic analysis.
Collectively, these patents provide a comprehensive, defensible solution that ensures data remains confidential and tamper‑resistant throughout its lifecycle, from the point of collection on the device to final analysis in the cloud.
Safety PLC Architecture
The Safety PLCs (SPLC‑X series) are designed to meet IEC 61508 and IEC 61511 safety integrity level (SIL) requirements. The architecture incorporates the following key elements:
- Dual‑Core Redundant Processing – two identical ARM Cortex‑A53 cores run identical firmware in lock‑step. A synchronizing interconnect ensures that both cores execute the same instruction stream with a 1 µs detection window.
- Fast‑Path Fault Detection – each core continuously monitors its own floating‑point unit, register files, and memory bus for parity and checksum errors. A dedicated Fault Detection Unit (FDU) compares the outputs of both cores every clock cycle (200 MHz clock, 5 ns period). Any discrepancy triggers an immediate fail‑safe transition.
- Safety‑Critical Interrupt Service Routines (ISR) – ISR handlers are coded in assembly to minimize latency. The ISR executes within 2 µs of fault detection, performing a watchdog reset or a controlled shutdown sequence.
- Hardware Safety Bus (HSB) – a dedicated bus that isolates safety‑critical data from non‑critical I/O. The bus uses a 5‑wire differential signaling scheme (LVDS) with 8 Gbps throughput to maintain low latency while preserving signal integrity.
- Safe‑Boot Verification – the PLC firmware image is signed with an RSA‑4096 key. During boot, the firmware's SHA‑256 hash is verified against the signature using the onboard HSM. A mismatch aborts the boot sequence.
- Redundant Memory & ECC – the PLC’s volatile memory is ECC‑protected. A parity check is performed on every access; a single‑bit error flips a fault flag that is immediately escalated to the FDU.
- Fail‑Safe State Transition – upon fault detection, the PLC switches to a pre‑defined safe state, disables all actuators, and publishes a Safety Event Log (SEL) via a secured MQTT broker. The SEL is timestamped and stored in the ASC for post‑incident analysis.
This architecture guarantees that faults are not only detected but also mitigated within milliseconds, ensuring continuous safety compliance for high‑risk industrial processes.
Data Security & Privacy Framework
Security in ASC is built on a layered approach. The first layer (device) ensures data is encrypted before it leaves the source. The second layer (network) uses secure communication protocols with forward secrecy. The third layer (cloud) performs privacy‑preserving analytics and secure key management. Each layer is protected by patents that provide robust legal protection against infringement and unauthorized usage.
Conclusion
Arnev’s suite of patents for the Secure Cloud not only protect the confidentiality of data but also provide privacy guarantees that are crucial for both consumer and industrial applications. By embedding these protections directly into the firmware and using a patented hierarchical key‑management scheme, ASC ensures that data remains secure across its entire lifecycle.
Q&A Session
To answer some of your specific questions:
- How does ASC handle massive IoT data streams?
- ASC uses a sharded, encrypted data lake that horizontally scales on AWS S3 with server‑side encryption (SSE‑S3). The data ingestion layer employs a patented “Batch‑Encryption Acceleration” that aggregates 10,000 packets per second without compromising encryption integrity.
- What is the latency for critical data?
- Device-to-cloud latency is ≤ 250 ms for BLE devices; ≤ 500 ms for Thread devices; ≤ 5 s for LoRaWAN devices. Cloud analytics are processed within 10 s after ingestion.
- How are privacy controls updated remotely?
- Remote firmware updates are signed with a fresh public key; the ASC’s KMP then re‑authenticates all devices with a new session key. The process is encrypted end‑to‑end, and the update is rolled out over a rolling window to minimize disruption.
- What are the key performance indicators (KPIs) for security?
- Security KPIs include Encryption Coverage (≥ 99.9 % of traffic encrypted), Incident Response Time (Key Rotation Frequency (daily), Zero‑Trust Validation Success Rate (≥ 99.999 %), and Replay Attack Prevention Rate (≥ 99.5 %).
