OEM PEPS Architecture with Native CAN Bus Integration
Engineered for specialty OEMs, custom ECU/PDU manufacturers, and commercial fleet applications.
Turnkey CAN Integration Stack & Protocol Deliverables
Eliminate months of proprietary CAN matrix development. The SEER platform operates as a dedicated cryptographic authentication node, managing key verification and broadcasting status frames directly to your BCM, VCU, or PDU while leaving final actuation logic under your controller’s authority.
Integration-Ready .DBC File
Drop-in database file ready for immediate import into Vector CANoe, CANalyzer, PCAN, Kvaser, or embedded code-generation pipelines.
- Supported bitrates: 250 kbps, 500 kbps (default), and 1 Mbps
- Bus definition: Pre-mapped message IDs, cycle intervals, endianness, and signal layouts
- Pre-mapped signal tables: Proximity zones, security authentication levels, immobilizer/start authorization, lock/unlock requests, power management control, and discrete I/O reporting and control
Session-Based Encrypted Communication
Stateful CAN communication using a dynamic session seed or message counter to derive unique encryption keys, paired with rolling counters to prevent frame reusage.
- Replay & Sniffing Defense: Defeats replay attacks, message sniffing, and packet injection
- Dynamic Authentication: Verified frame freshness and real-time message authentication
- Negotiation Mode: Dedicated negotiation mode for secure session initialization and unique session key derivation
Turnkey Firmware Integration & SDK
A complete firmware integration package detailing the state machine from initial wake-up to session closure, designed to cut integration development time.
- Session Flow Documentation: Clear handshake guides covering initialization, counter negotiation, standard communication, and fault recovery sequences.
- Firmware Integration Templates: C-code templates for CAN session initialization, session communication, and message integrity verification.
- Full Encryption Implementation: Highly portable, ready-to-use C-source files for session key generation and payload encryption.
- Firmware Integration Support: Direct collaboration with our engineering team to assist with state-machine alignment, cryptography porting, and protocol validation.
Hardware-Level Defense & Fail-Safe Redundancy
Field-proven RF architecture engineered to prevent modern automotive theft vectors while preserving absolute emergency access.
Anti-Relay & Replay Immune
Proprietary encrypted challenge-response handshakes prevent signal amplification and relay attacks common on modern factory keyless vehicles. Tier-1 cryptographic validation built directly into the node.
Low-Battery Inductive Fail-Safe
Eliminates stranded operator scenarios. If the key fob battery is depleted, an integrated LF transponder authenticates unlock and engine start when placed adjacent to the designated vehicle backup point.
Primary Wake-Up Circuit Output
A dedicated low-latency digital output toggles high upon valid fob approach, waking your BCM, VCU, or PDU from deep sleep before the operator touches the door, minimizing host standby drain.
Multi-Tier Power Management Architecture
Engineered for performance platforms, collector builds, and fleet equipment requiring extended standby without 12V battery depletion.
| Operating State | Trigger / Inactivity Threshold | Typical Current Draw |
|---|---|---|
| Active Authentication Handshake | Key fob present within active calibration boundary | ~58 mA |
| Standard Operational Standby | Active vehicle readiness / initial parked state | 24 mA |
| Stage 1 Tiered Sleep | 12 hours continuous inactivity | 18 mA |
| Stage 2 Extended Sleep | 48 hours continuous inactivity | 14.5 mA |
| Stage 3 Deep Sleep | 72 hours continuous inactivity | 12.5 mA |
| Ultra-Deep Battery Preservation | 7+ days inactivity (programmable thresholds) | 4.8 mA – 1.0 mA |
