DataLockRNG is an implementation of the hash_DRBG algorithm as defined by NIST SP800-90 using SHA-256 as its hashing function. A 256 bit non-deterministic entropy source is input to the deterministic hash_DRBG algorithm (NIST Validation No. 164 and 177). This means identical units will generate a unique sequence of random numbers.
It's available as a stand-alone IC for integration with customer products. Access to random number functions is via a serial interface (I2C, RS-232, or SPI). Possible uses include the generation of an encryption key for secure mass storage*, as a source of random numbers for door locks, or a source of private keys in a web based application.
