Abstract: Micro-scale planar-coil transformers including one or more shields are disclosed. The one or more shields can block most common-mode current from crossing from one side to another side of a transformer. Reduction of common-mode current crossing the transformer results in reduction of dipole radiation, which is the main component of electromagnetic interference (EMI) in some transformers.

Abstract: Power isolators for providing electrical isolation between an input port and an output port that exhibit low electromagnetic interference (EMI) are described. The low EMI may be achieved by, for example, canceling out a common mode current across a transformer in the power isolator that may be converted into EMI. The power isolator may include at least one oscillator circuit that is configured to apply a first signal to a first transformer and a second, different signal to a second transformer. The first and second signals may be configured such that the common mode current generated in each of the first and second transformers has an opposite direction. Thus, the common mode currents in the first and second transformers may at least partially cancel out. As a result, the EMI exhibited by the power isolator may be reduced.

Abstract: The disclosure proposes a format-preserving encryption method based on a stream cipher. In this method, the first three digits of an area code are encrypted by segmenting a phone number, creating mapping rules, and establishing an area code permutation table for the first three digits of the area code, thereby ensuring a legality of an encryption result; an accuracy of encryption and decryption is ensured by performing an XOR operation on a key stream generated from the ZUC algorithm (i.e., Zu Chongzhi's algorithm) and the last seven or eight digits of the phone number, combining a modulo operation to achieve conformal encryption, and introducing a Lagrange interpolation formula. This method securely and effectively realizes a consistency and legitimacy of data formats before and after encryption, and well hides statistical characteristics of plaintext, so that data is protected during a transmission process without changing the formats.
