WebWhen you call aes (size = 2) it creates a variable called `2` and uses that to create the size, mapping it from a constant value as it is within a call to aes (thus it appears in your legend). Using size = 1 (and without reg_labeller which is perhaps defined somewhere in your script) WebNote that the size is constant along the diagonal in the following figure. sizes <- expand.grid (size = (0:3) * 2, stroke = (0:3) * 2) ggplot (sizes, aes (size, stroke, size = size, stroke = stroke)) + geom_abline (slope = -1, intercept = 6, colour = "white", linewidth = 6) + geom_point (shape = 21, fill = "red") + scale_size_identity () Text

Websize of 128 bits and a choice of three keys -128,192,256 bits. Depending on which version is used, the name of the standard is modiﬁed to AES-128, AES-192 or AES-256 respectively. As well as these differences AES differs from DES in that it is not a feistel structure. Recall that in a feistel structure, half of the data block is used to WebAnswer (1 of 2): 128 bits - this was mandated by the agency (NIST) who set up the AES competition - and is the smallest block size the winner (Rijndael) supports. It also supports 192 and 256 bit block sizes. Similarly, AES supports only 128, 192 and 256 bit key sizes; Rijndael also supports 160...
