The COVID-19 coronavirus has caused a devastating global pandemic, with rapidly increasing case counts and deaths worldwide. The number of confirmed cases and fatalities exceed 83,113,878 and 1,812,218 globally. In the US, there were 19,821,487 and 343,818 confirmed cases and deaths as of the end of 2020 [1]. It boggles the mind how COVID-19 descended into a conspiracy theory, pitting politics against science, while millions of lives are lost and so many more are suffering from grief and pain, pointlessly.

Modern ciphers deceive statistical analysis thanks to complex algorithms and ciphering keys. The very first concept of these can be found in a 1466 manuscript by Leon Battista Alberti, the importance of which was for many years overlooked. This paper focuses on the work by Alberti and its impact, within the framework of a brief and necessarily incomplete history of cryptography.","PeriodicalId":101270,"journal":{"name":"URSI Radio Science Bulletin","volume":"2020 375","pages":"55-63"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/7873543/9663119/09663133.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50329251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
