A plurality of control units each with at least one entropy source are formed. Their raw data are transmitted to the aggregation component via the vehicle network. A quality assurance of the combined raw data from the entropy sources is carried out using only those combined raw data which both occur in a non-deterministic manner and contain a minimum degree of entropy as qualified raw data. The qualified raw data are converted into an aggregated data block by a cryptographic one-way function and securely stored as a random number in the storage unit. The random number stored in the storage unit is transmitted to a control unit via the vehicle network by the distribution component.

An authentication unit of an information processing apparatus authenticates an update control device that controls update of a control program by using a random number generated by a random number generation unit. In the random number generation unit, a first extraction unit extracts a bit value from a count value of a first clock signal, a calculation unit performs logical operation on the bit value extracted by the first extraction unit and a target bit value at a bit position included in an entropy as an update position that is designated, a replacement unit replaces the bit value at the update position with a result of the logical operation a position designation unit designates a new update position after the bit value is replaced, and an output unit generates the random number from the entropy.

A system and method of quickly and efficiently generating a series of random numbers from a source of random numbers in a computing system, Steps includes: loading a data loop (a looped array of stored values with an index) with random data from a source of random data; then repeating the following: reading a value from the data loop in relation to the index; operating on the multi-bit value thereby outputting a derived random number; and moving the index in relation to the looped array. The data loop may be a simple feedback loop which may be a shift register loaded by direct memory access (DMA). The operation may be performed by one or more arithmetic logic units (ALU) which may be fed by one or more data feeds and may perform XOR, Mask Generator, Data MUX, and/or MOD.

A filter request for a data set indicates a query specification and one or more sub-range indicators of a disjoint subset descriptor. Corresponding the individual data records obtained from the data set using the query specification, a respective range mapping value is generated. Using the range mapping values and the sub-range indicators, a result set of the filter request is obtained.

A random number generator is implemented within a digital processor by: a) searching an internal timestamp register which counts clock pulses for sequencing the processor; b) extracting at a given time n bits from the least significant bits of the register, n>1; c) using the n bits extracted at step b) as constituent bit(s) of a N-bit random number (34) to be generated; d) reiterating steps a) to c) until obtaining the N bits of the random number; and e) providing the random number to an application circuit or software.
