摘要： A memory card and a recording/playback device are provided that are capable of deterring a memory card manufacturer from illicitly storing a same media ID on a plurality of memory cards. A memory card (100) includes a media ID storage module unit (610) and a memory unit (120). The media ID storage module unit (610) includes a media ID storage unit (611) that stores therein a media ID that is specific to the memory card, and a certification unit (609) that generates certification information that certifies the validity of the memory card based on the media ID. The memory unit (120) includes an encrypted content storage unit (122) for storing encrypted digital content. The recording/playback device (200) includes a memory card verification unit (200) that acquires the certification information from the memory card (100), verifies the validity of the memory card (100) based on the acquired certification information, and when the verification has failed, prohibits decrypting an encrypted content or encrypting a content, and a content encryption unit (209) that, when the verification has succeeded, encrypts the digital content or decrypts the encrypted digital content.

摘要： Disclosed are methods and circuits for detecting and recording timestamps for multiple events (222/322, 224/324) using a single input pin (252, 352) on a real time clock (RTC) (250, 350). Signals associated with each of the events are modulated to create a multiple level composite signal (240). The RTC includes a multiple signal level detection circuit to distinguish from among the various signal levels so that each event can be separately flagged and timestamped. For example, the opening of two or more covers (112, 114) on the housing (110) of an electronic device (100) can be monitored, distinguished, and separately flagged using a single RTC input port.

摘要： This invention relates to a method and system for providing digital security by means of a reconfigurable physical uncloneable function, RPUF. The RPUF comprises a physical system constituted by distributed components arranged to generate a first response when receiving a first challenge at a point of the physical system. The physical reconfiguring of the RPUFcomprises redistributing the components such that they generate a second response, which differs from said first response, when again applying the first challenge at the point. The reconfiguration step is further utilized in providing secure storage for digital items. The digital item is data of any kind, including data that needs to be accessed and updated, i.e. which is dynamic in nature. The method is exemplified by implementations such as secure storage of a key, a secure counter and a seed generator.

摘要： First and second portions of memory are provided in a storage module (e.g. hard drive or flash card). The first portion is for storing content (e.g. music, videos, pictures) and the second portion is for storing information (e.g. keywords or tables of content) required to access the content. When, unauthorized use of the storage module (disconnection from a playing device, opening the module, opening a playing device containing the module, attempting to access content when the module is disconnected from an authorized playing device) is detected then further access to the information stored on the second part is prevented. Access can be prevented, for example, by blank erasing the second portion. A power source (e.g. battery) is provided for the detecting and preventing of access, the access also being prevented if the power source fails.

摘要： In accordance with the invention, a postal security device (PSD) (10) contains a non-volatile memory (13) which does not depend on battery power such as an EEPROM (13), and contains a nonvolatile memory (14, 16) which does depend on battery power, such as a static RAM. The PSD (10) also contains an encryption engine (12, 14, 22). An encryption key is developed and is stored in the static RAM (14), which is sized to be only large enough to contain the encryption key. A large body of data, too large to fit in the static RAM, is encrypted by means of the encryption engine (12, 14, 22) and with reference to the encryption key, and is stored in the EEPROM (13). This body of data typically includes cryptographic keys and sensitive bit-images. When the PSD is powered, a large RAM (typically a dynamic RAM) (16) is available to receive the large body of data, decrypted using the encryption key. A tamper switch (17) cuts power to both RAMs (14, 16) in the event of tampering.
