摘要： A method of accessing content includes installing a file system filter for a secure removable memory device on a host device. A challenge is sent from the file system filter to a software entity on the host device, and a software entity response is received at the file system filter in response to the challenge. A file system filter response is calculated at the file system filter using the challenge, and access to first content on the secure removable memory device is provided if the software entity response matches the file system filter response.

摘要： A software entity on a host device attempting to access protected content in a secure memory device must be authenticated using a challenge/response authentication mechanism before the secure file system can be accessed. A file system filter determines whether requested content is protected. If the content is protected, the file system filter provides a challenge to the software entity and generates a file system filter response using the same challenge. The software entity must then send a software entity response using the challenge to the file system filter. If the file system filter determines that the software entity response matches the file system filter response, the software entity is allowed to access the protected content through a secure file system installed on the host device for the memory device.

摘要： Techniques are presented for sending an application instruction from a hosting digital appliance to a portable medium, where the instruction is structured as one or more units whose size is a first size, or number of bytes. After flushing the contents of a cache, the instruction is written to the cache, where the cache is structured as logical blocks having a size that is a second size that is larger (in terms of number of bytes) than the first size. In writing the instruction (having a command part and, possibly, a data part), the start of the instruction is aligned with one of the logical block boundaries in the cache and the instruction is padded out with dummy data so that it fills an integral number of the cache blocks. When a response from a portable device to an instruction is received at a hosting digital appliance, the cache is similarly flushed prior to receiving the response. The response is then stored to align with a logical block boundary of the cache.

摘要： In order to write data to a storage system accessible with a first and second file system, a manager receives a data write request associated with a file. The manager determines if a function supported by the second file system is needed to complete the write request. If so, the file is opened and extended with the first file system. The file is then opened and written to by the second file system. The file is truncated by the first file system, and closed by both file systems. If the second file system function is not needed, the file is opened, written, and closed by the first file system. In order to read data from a storage system using a function supported by the second file system, the second file system's cached storage system index is updated, then the file is opened, read, and closed by the second file system.
