Latest Patents

One of Seo-Kyu Kim's latest patents is a method, apparatus, and computer program for processing multimedia data signals. This invention describes an apparatus that includes an input switch to receive multiple transport stream packets corresponding to various digital multimedia data signals. The apparatus features a packet identification (PID) filter unit that selectively outputs a specific set of TS packets for demultiplexing. Additionally, a buffer or external memory device is utilized to store some of the output TS packets. A conditional access/content protection (CA/CP) unit is also included, which reads and decrypts the stored TS packets, ensuring that they are encrypted again for storage in the external memory device to prevent unauthorized copying.

Another notable patent by Kim involves smart cards equipped with protection circuits to inhibit power analysis attacks. This smart card contains an integrated circuit device with secure information. The protection circuit is designed to prevent unauthorized retrieval of this secure information by maintaining a uniform voltage on the power supply line when the integrated circuit is active. This innovative approach masks the operations of the integrated circuit, making it difficult for external hardware to exploit power analysis techniques.
