In this study, we aim to propose a new framework of randomness testing based on random mappings. Considering the probability distributions of coverage and P-lengths, we present three new distinguishers; (i) coverage test, (ii) p-test and (iii) DP-coverage test and applied them on Phase III Candidates of eSTREAM project. We experimentally observed some statistical weaknesses of Po-maranch using the coverage test.eninfo:eu-repo/semantics/closedAccessRandom MappingsTmto AttacksRandomness TestsStream CiphersConference Object520330+10.1007/978-3-540-85912-3_32-s2.0-56449111692WOS:000260673100003N/AQ3
