Ganga is an indigenously designed and developed cryptographically secure pseudo random number generator released as a Kernel module, aimed for use in strategic applications. Ganga generates random bitstreams of arbitrary length which are provably secure and has a unique design to generate non-reproducible random bitstream as reported for the first time in the literature. Ganga has undergone rigorous security validations to confirm its suitability for cryptographic applications.
