A vast majority of cryptographic/security solutions in the area of information technology depends on the quality of secret data called (cryptographic) keys that based on random numbers. There is a substantial difference between random numbers used for cryptographic and other, e.g. simulation, purposes, and the area of (pseudo)random number generation is one of the most active areas of cryptography and security research. Truly random sequences are extremely difficult to generate in computing environments, namely when considering the (expected) deterministic behaviour of computer systems. Thus we often restrict ourselves to the use of (deterministic) pseudorandom sequences instead. Such sequences should not be distinguishable from truly random sequences, and are generated from (typically shorter) inputs that should be of a random nature. This project focuses on the following three areas: (1)Definition of properties for mechanisms usable for cryptographic pseudorandom number generation, (2) analysis of options for generating truly random sequences in the mobile environment, with the vision of providing a unique comprehensive review of currently used options for random sequence generation, (3) review of properties of sequences that can be generated from biometric data, where we aim to investigate a completely novel use of biometric data.
