Application Areas
Quantum cryptographic systems ensure the absolute and everlasting security of communications across a broad spectrum of end uses. QuintessenceLabs QKD systems are designed to suit numerous applications. Some of the most common applications include:
- Link encryptors
- Ultrasecure optical fibre networks
- Wireless Point to point
- Satellite QKD Uploads
- Handheld devices
Link encryptors
Link encryption ensures the secure communication of information in transit through an optical network. QuintessenceLabs QKD link encryption operates in real time and is transparent to all higher layer communications protocols. Link encryption is necessary when the security of a transmission channel cannot be assured, and it is not possible or desirable to modify existing communications protocols and equipment. For certain applications, including law enforcement and intelligence, link encryption is mandatory.
Ultrasecure optical fibre networks
QuintessenceLabs QKD provides ultrasecure communications over:
- optical fibre metropolitan area networks
- direct point to point coverage up to 20 km
- extended range possible using relay stations
- tactical last mile fibre
- optical local area networks (LANs) for in-house high performance security
Wireless point to point
Wireless systems provide the same ultrasecure encryption of a standard QuintessenceLabs QKD system, but offer a low cost alternative for short range communications between sites where a dedicated fibre link is not essential. There are two types of wireless systems available:
Free Space optics:The free space optics package uses line-of-sight laser transmission between rooftop systems, providing true one-time-pad data encryption over a 2km radius.
Microwave:Similar to free-space optics, but incorporating microwave communications instead of lasers, this system supports longer haul metro line-of-sight data encryption but at a reduced data rate than the free space optics system.
Satellite communications
Current communication & military satellites are launched with a pre-defined encryption key sequence that, once exhausted cannot be refreshed. This defines the effective life of a satellite to be dependent on the quantity of data transmitted, rather than on the useable life of its hardware. Using a laser uplink and QuintessenceLabs QKD technology the encryption key database of a satellite can be securely re-keyed thus extending its useable life.
Handheld devices
Our quantum cryptographic system can also be integrated into handheld devices to transfer secure material, by means of true one-time pad encryption, between handsets without risk of interception.
