Quantum Side-Channel Attacks: Beyond Algorithm Cracking

Описание: Quantum security threats aren’t just limited to the algorithm level—they also hide in the physical vulnerabilities of hardware. This is what we call quantum side-channel attacks.
Attackers don’t need to crack encryption algorithms. Instead, they can steal keys or sensitive data by analyzing the physical characteristics of quantum devices—such as QKD terminals or quantum computer chip s—during operation. These characteristics include fluctuations in photon emission intensity, changes in energy consumption, and even differences in device heat dissipation.
This type of attack is highly targeted. The core response is to add a "physical protective shield" to quantum devices, such as optimizing the stability of single-photon sources and real-time monitoring for abnormal physical parameters of the equipment.#uqb #web3 #quantumsecurity #crypto
