  • Patent number: 7937593
    Abstract: Systems and methods that storage device content authentication are provided. A system that verfies storage device content received from a storage device may comprise, for exmple, a security processor coupled to the storage device. The security processor may be adapted to receive a partitioned storage device region from the storage device. The partitioned storage device region may comprise, for example, regional content and first hashed regional content. The security processor may generate, for example, second hashed regional content by performing a hashing function on the regional content received by the security processor. The security processor may compare, for example, the first hashed regional content to the second hashed regional content. The security processor may varify the regional content received by the security processor if the first hashed regional content is the same as the second hashed regional content.

  • Publication number: 20100306556
    Abstract: A method for securely handling processing of information in a chip may include randomly selecting one of a plurality of data processes based on a random process index. A time interval may be randomly allocated on the chip, for processing the randomly selected one of the plurality of data processes. When the randomly allocated time interval has elapsed, the randomly selected one of the plurality of data processes may be initiated. The randomly selected one of the plurality of data processes may include one or both of accessing data and acquiring the data. Data may be verified by the randomly selected one of the plurality of data processes prior to the processing of the data. The data may be verified utilizing at least one digital signature verification algorithm, such as a Rivest-Shamir-Adelman (RSA) algorithm and/or a secure hash algorithm (SHA-1).
