Application: Method and electronic device for decrypting homomorphically encrypted data (Patent ID: US20230353376A1)
The patent by NXP Semiconductors NV describes a method and electronic device for decrypting homomorphically encrypted (HE) data. The method involves generating result metadata specifying the size of the HE data to be decrypted, encrypting the metadata, transmitting the HE input data and encrypted metadata to a cloud server for computations, establishing a secure connection to a secure element in the cloud, and enabling the secure element to decrypt the computations based on the metadata. The electronic device acts as an edge device for an internet of things system, and the secure element uses a HOTP token for decryption.
The method further includes synchronizing keys and counter values between the secure element and the electronic device, using a symmetric authenticated encryption scheme for metadata encryption, and sending the decrypted computations back to the cloud server. The secure element can be part of the cloud server, and the computations on the HE input data can be performed using a machine learning model. Additionally, the electronic device can generate an output hash for comparison with the HOTP token, increment the counter value after decryption, and provide the decrypted results to the cloud server. The electronic device also includes a processor for generating encrypted metadata, a data generator for HE input data, and a network interface for transmission to the cloud server, enabling decryption by the secure element based on the specified metadata size.
