Abstract: A system for implementing a quantum-based data validation in a network is disclosed. The system generates a quantum key for data packet transmissions. The system distributes the quantum key among a set of end-point devices, where the set of end-point devices are each authorized devices. The system encrypts the data packet with the quantum key. The system receives a request message to access the data packet, where the request message comprises an identifier associated with a requesting device. The system determines whether the request message is originated from an authorized entity by determining whether the identifier associated with the requesting device is recorded as an authorized entity in a blockchain database. If it is determined that the request message is originated from an authorized entity, the system grants access of the data packet to the requesting device. Otherwise, the system denies the request.

Abstract: A portable device for detecting and mitigating skimming/malicious devices that attempt to gain access to information associated with the portable device is disclosed. The portable device detects the first electromagnetic signal associated with an external device and determines the first set of attributes associated with the first electromagnetic signal. The portable device compares the first electromagnetic signal with an expected electromagnetic signal by comparing each attribute from among the first set of attributes with a corresponding attribute associated with the expected electromagnetic signal. The portable device determines a difference between the first electromagnetic signal and the expected electromagnetic signal based on the comparison. If the determined difference is more than a threshold value, the portable device performs one or more countermeasure actions including an emission of the particular electromagnetic signal via the electromagnetic signal emitter.

Abstract: A system for detecting and mitigating unauthorized access and tampering with respect to a device is disclosed. The system detects an event that indicates an attempt to access a portable device, where detecting the event comprises detecting a mixed signal associated with an external device. The system determines a set of frequencies associated with the mixed signal. The system compares a first frequency from the mixed signal with a set of authorized frequencies. The system determines that the first frequency is not among the set of authorized frequencies. In response, the system determines that the first frequency is associated with a malicious device. The system performs one or more countermeasure actions.
