Ciphertext-only attack on d*d Hill in O(d13d)

Hill is a classical cipher which is generally believed to be resistant against ciphertext-only attack. In this paper, by using a divideand-conquer technique, it is first shown that Hill with d× d key matrix over Z26 can be broken with computational complexity of O(d26), for the English language. This is much less than the only publicly known attack, i.e., the brute-force with complexity of O(d2...

Graham-Little syndrome.

Graham-Little syndrome, also know as Graham-Little-Piccardi-Lassueur syndrome, is an unusual form of lichen planopilaris, characterized by the presence of cicatricial alopecia on the scalp, keratosis pilaris of the trunk and extremities, and non-cicatricial hair loss of the pubis and axillae. We present the case of a 47-year-old woman whose condition was unusual in that there was a prominence o...
