An integrated circuit device that includes a secure or protected memory component is herein disclosed and enabled. The integrated circuit device may be a wireless communication device or a smart card or a USB device. Additionally, the integrated circuit device may be part of, or included in, a computing device or a mobile device. The integrated circuit device includes a protected memory section for storing protected data that is not accessible by a user at the protected memory section, but is accessible by a memory controller included in the integrated circuit device. The memory controller accesses the protected data with a combination of security operations that may include cryptography. The integrated circuit device may further include a wireless component for establishing a wireless connection with wireless computing devices or readers for wirelessly transmitting the protected data accessed by the memory controller to the wireless computing devices or the readers.
1. A wireless integrated circuit memory device for wirelessly transmitting encrypted data from the wireless integrated circuit memory device to a wireless device, over local point to point wireless communication, the wireless integrated circuit memory device comprising:
a memory controller;
memory that includes a protected memory area for storing protected data, the protected data stored in the protected memory area is not accessible by a user of the wireless integrated circuit memory device, from the protected memory area, but is accessible by the memory controller; and
wireless communication circuitry for the local point to point wireless communication, wherein the wireless integrated circuit memory device is operable to:
(1) access, by the memory controller of the wireless integrated circuit memory device, the protected data that is stored in the protected memory area, the access of the protected data from the protected memory area is based on the memory controller implementing a cryptographic algorithm;
(2) encrypt data, at the wireless integrated circuit memory device, into the encrypted data, the data is related, at least in part, to the protected data accessed by the memory controller in (1) from the protected memory area of the wireless integrated circuit memory device;
(3) wirelessly discover, over the local point to point wireless communication and using the wireless communication circuitry of the wireless integrated circuit memory device, the wireless device;
(4) establish, using the wireless communication circuitry of the wireless integrated circuit memory device, a local point-to-point wireless communication link between the wireless integrated circuit memory device and the wireless device that is wirelessly discovered in (3), the local point-to-point wireless communication link being a radio communication link;
(5) wirelessly transmit, using the wireless communication circuitry of the wireless integrated circuit memory device, at least part of the encrypted data encrypted in (2), over the local point-to-point wireless communication link that is established in (4), directly from the wireless integrated circuit memory device to the wireless device that is wirelessly discovered in (3); and
(6) wirelessly receive, using the wireless communication circuitry of the wireless integrated circuit memory device and over the local point-to-point wireless communication link established in (4), information from the wireless device wirelessly discovered in (3), the information is related to one or more of payment information, status information, or output process information, individually or in any combination; and
wherein the wireless integrated circuit memory device provides protection of the protected data by storing the protected data in the protected memory area and requiring use of the wireless integrated circuit memory device for wirelessly transmitting the encrypted data directly from the wireless integrated circuit memory device to the wireless device in (5).
