Discretix Cryptographic Engines
Discretix cryptographic engines are widely deployed in leading
system-on-chip solutions. Discretix provides highquality,
ready-to-use cryptographic engines, to support variety of
applications. Included in Discretix’s family of cryptographic
engines are symmetric ciphers, asymmetric ciphers, Hash and
random number generators.
DxRNG - General Description
The DxRNG provides a full implementation including true and pseudo random number
generation. Random numbers are primarily used in cipher key generation for secure
data communications, secure data storage and timers in communication protocols.
The DxRNG includes two RNG cores. The TRNG core provides True Random Number Generation,
with continuous auto correlation self-test of bit stream. The TRNG core eliminates
noise generation and checks for random bit stream bias. The PRNG core provides generation
of pseudorandom bit stream based on a given seed. The seed can be provided either
directly from the TRNG core or by the host processor through a register interface.
The two RNG cores (TRNG and PRNG) are easily integrated together to provide a complete
RNG solution, or can be used as stand alone modules.
The DxRNG engine has two main interfaces: A CPU interface for configuration and
random bits collection, and
an interface to a source of entropy. Once random bits
are read, a new random set of bits is generated.
