{"Image DocumentName": "Monoalphabetic Cipher Security", "Image ImageDescription": "Now have a total of 26! = 4 x 1026 keys. With so many keys, might think is secure. What\u2019s the problem? Note that even given the very large number of keys, being 10 orders of magnitude greater than the key space for DES, the monoalphabetic substitution cipher is not secure, because it does not sufficiently obscure the underlying language characteristics.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
