    Abstract: Random values can be very beneficial in systems needing to generate random number or encryption keys. Systems and methods are presented herein that can generate a random value based on errors in data. For example, an error vector can be generated when data having errors (e.g. stored data, data received by a receiver, etc.) is compared with corresponding corrected data. A circuit, such as a data channel, can generate the corrected data by applying error correcting codes to the data with errors. One or more error vectors may be used to produce a random value. In some cases, multiple error vectors can be combined to produce a random value.

    Abstract: Security techniques may be selectively performed on data based on a classification of the data. One example technique includes receiving a memory access command specifying a target data block on a storage medium storing both security data and non-security data. The technique further includes determining whether data affected by the access command is security data. Response to such determination, one of multiple data management schemes is selected to implement the memory access command, where each of the data management schemes is adapted to implement the memory access command via a different series of processing operations to provide a different level of security protection for data affected by the memory access command.

    Abstract: Apparatus and method for generating random numbers. In accordance with some embodiments, a first multi-bit string of entropy values is derived from a first entropy source having a first trust level and a different, second multi-bit string of entropy values is derived from a second entropy source having a different, second trust level. The first and second multi-bit strings of entropy values are combined in relation to the associated first and second trust levels to generate a multi-bit random number. The multi-bit random number is used as an input to a cryptographic function.

    Abstract: Systems and methods for calculating random values based on data errors are presented. A message collection circuit may collect sets of data having data errors and store them to a memory. The stored sets of data may then be processed to produce a random value based on errors in the sets of data. The random value(s) may be provided to random number generator(s), encryption circuit(s), or other circuit(s).
