A secure chip implements data security protection through hardware-level design: the CPU cores adopt physical isolation between secure and non-secure zones; the security engine uses dedicated hardware to accelerate cryptographic operations and prevent data leakage; secure storage employs hardware protection techniques such as dynamic address mapping, forming a closed-loop security model of "data never lands in plaintext, computation never leaks, and access is controlled." Jahport secure chips also integrate PUF, TRNG, and anti-SPA/DPA technologies, effectively defending against side-channel attacks, fault injection, and other physical-layer threats—capabilities that software-based encryption on general-purpose chips cannot match.

PUF leverages the intrinsic microscopic physical variations in chip manufacturing processes (such as random threshold voltage fluctuations of transistors) to construct a physically unclonable mechanism, generating a unique innate hardware fingerprint for each chip. The inherent randomness makes it extremely difficult for attackers to obtain identical characteristics through reverse engineering or physical replication. Based on PUF, dynamic key generation and instant destruction after use can be achieved, fundamentally solving the challenge of secure key storage. Jahport JC100/JC120/JC130 anti-counterfeiting authentication chips and JA700 automotive-grade chip all integrate PUF technology.

PQC (Post-Quantum Cryptography) is a new generation of cryptographic algorithms capable of resisting quantum computing attacks. Shor's algorithm in quantum computing can break traditional public-key systems such as RSA and ECC. Given the long automotive R&D cycle and vehicle service lives of up to 15-20 years, the industry faces the long-term threat of "harvest now, decrypt later". The Jahport JA700 automotive-grade security SoC natively supports the standardized PQC algorithms ML-KEM (Kyber), ML-DSA (Dilithium), and SLH-DSA (Sphincs+), adopting an integrated classical public-key and post-quantum design to provide future-proof quantum-resistant security for V2X communication, certificate issuance, and OTA upgrades.

Find My products require Apple MFi certification, while Find Hub products must comply with the Google Nearby specification, and the Bluetooth portion also requires BQB certification. Jahport is an officially certified secure Bluetooth SoC partner of both Apple and Google. The JC511 (BLE 5.2) and JC521 (BLE 5.4) secure Bluetooth SoCs have both passed BQB certification and comply with dual-ecosystem standards, providing full lifecycle support from solution design and pre-testing to mass production launch, covering complete capabilities including end-to-end encryption, anti-tracking detection, lost mode, and remote control.

The primary certifications for automotive-grade chips include AEC-Q100 (reliability; Grade 1 requires an operating temperature of −40°C to 125°C) and the CC EAL security evaluation standard. Jahport JA700 complies with the AEC-Q100 Grade 1 and CC EAL5+ certification standards. It has also obtained Commercial Cryptography Product Certification (Level 2). The chip offers a 20-year operating life, an MSL3 moisture sensitivity rating, and ±2 kV HBM ESD protection. It is suitable for V2X roadside units, automotive security gateways, high-temperature domain controller modules, and deployments in environments outside the vehicle cabin.

Jahport's accessory anti-counterfeiting solution delivers encrypted management for every accessory and consumable through secure chips. Only accessories and consumables that pass chip-based cryptographic verification can be recognized and accepted by the host device. Built on the JC100 Series PUF anti-counterfeiting chip, the solution enables hardware-level authenticity verification with a unique identity per item, providing end-to-end encrypted traceability from production through replacement. It supports SM2/SM3/SM4 Chinese cryptographic algorithms alongside AES/ECC/RSA/SHA international algorithms and is compatible with mainstream solutions, enabling deployment in printer ink cartridges, medical device accessories, purifier filters, batteries, and other consumables for anti-counterfeiting without major hardware or software changes.

Jahport provides full-lifecycle support covering chip selection, solution design, production testing, and end-user application, including the Bothnia secure operating system and Jawind-API middleware, a GEM5-based high-fidelity secure application development platform, algorithm libraries and design review, mass production tools and pre-certification services, as well as platform systems such as Identity Management (SummerCool), SM-DP Data Preparation (Dhaulagiri), Chip Personalization (Paradiso), Key Management (CryptoBase), TOKEN Service (Makalu), Remote Application Distribution (Annapurna), CA Authentication (Gompa), and Trusted Service Management (Everest). Pre-sales support covers chip selection and customization; in-sales support covers on-site installation and commissioning; after-sales support provides comprehensive service assurance.

Key specifications include: Sleep/PD mode current (determines battery life), wake-up time, security operation power consumption, and package size. Taking Jahport JC511 as an example, Sleep mode (64KB RAM retention) is only 1.2μA@3V, and PD mode is as low as 130nA; paired with a CR2032 coin cell battery, the anti-loss tag can last over a year. JC100 supports multi-level power management. When selecting, also confirm security capabilities (PUF, TRNG, SPA/DPA resistance) and target ecosystem certifications (e.g., Apple MFi, Google Nearby).
