Secure transmission of data in communications based on constrained devices is an understudied issue with severe consequences, as it may jeopardize the entirety of a network's security. Most cryptographic methods are based on random numbers, however, obtaining these proves challenging on devices with such low computational power. In this paper, we evaluate the use of postprocessing techniques to increase the quality of randomly generated numbers in 32-bit RISC-V processors, within the context of a blockchain network. Through these methods an increase of entropy of 80% was achieved.
