The proposed pseudorandom sequence generator is a practical zero-memory information source, with a discrete set of possible values of varying size, obtained through successive random variable transformations applied to the chaotic map. We exemplify on a particular case of the generalized Hénon map. The paper also presents an example of using a pseudorandom chaotic sequence in an enciphering chain, applied to images. The chaotic sequences are studied through conventional statistical methods and also using the NIST test suite. They satisfy the respective randomness requirements.","PeriodicalId":366043,"journal":{"name":"2014 10th International Conference on Communications (COMM)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133130611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
