Security
With the rapid rise of IoT and AI, security has become a critical concern.
The foundation of information security lies in three principles:
Confidentiality
protecting data from unauthorized access
Integrity
ensuring data remains accurate and unaltered
Availability
keeping systems and data accessible to authorized users
To uphold these, modern security solutions integrate cryptography, access control, and hashing algorithms.
Security Technologies
A reliable hardware root of trust ensures:
- Confidentiality - Data stays private
- Integrity - Data remains unchanged
- Authenticity - Devices are verified
- Non-repudiation - Actions can’t be denied
For AI, IoT, automotive, and more, chip-level security offers stronger, more reliable protection.
Unclonable Random Number Seeds
A PUF (Physically Unclonable Function) acts as a unique silicon fingerprint, generated from natural variations in chip manufacturing. It enables secure key generation for authentication, digital signatures, and secure boot.
Unlike traditional HSMs that require cleanrooms and external storage, PUFs generate and store secrets directly on-chip — reducing cost and complexity while enhancing security.
Flexible Integration
Security isn’t one-size-fits-all — a smart band and an autonomous vehicle demand very different levels of protection.Our solutions offer flexible combinations of secret key generation, crypto engines, and TRNGs to meet diverse protocol and system needs.
They’re also easy to adopt across various foundries and process nodes, streamlining integration for any chip design.
Hardware Security
Compared with software-based security measures, hardware solutions can provide a more solid security boundary against hostile attacks. Nowadays, more people are talking about hardware root of trust-based security protections for devices that they’ve spent huge amounts of time and human resources to create.
Hardware security provides faster response time, less vulnerability and simpler protection than a software approach.
