Abstract

The invention relates to the field of semiconductor optoelectronics, in particular to an optical PUF system based on chaotic signals, which is used in fields such as security verification and key generation. The initial value sensitivity and high bandwidth characteristics of chaotic signals are used to solve the problems of low security and small amount of information in current optical physics unclonable function systems. The use of a silicon waveguide structure is conducive to integration with other semiconductor functional devices, which is expected to realize a compact security verification system and random number generator.

Description

technical field

[0001] The invention relates to the field of semiconductor optoelectronics, in particular to an optical PUF system based on chaotic signals. Background technique

[0002] With the rise of Internet of Things technology, the application prospect of Physical Unclonable Function (PUF) is increasingly prominent. PUF has uniqueness, unclonability, unpredictability and robustness. These characteristics make PUF widely used in true random number generation, high-speed encryption key generation and authentication.

[0003] At present, there are two main implementations of PUF, that is, the electro-physical unclonable function proposed by using the randomness of the integrated circuit manufacturing process error and the optical implementation method proposed by using the complexity of optical diffraction. Compared with electrical PUF, optical PUF is more secure, and the faster transmission speed of photons makes it more suitable for application in the field of informa...
