This paper presents a weakness in the key schedule of the AES candidate HPC (Hasty Pudding Cipher). It is shown that for the HPC version with a 128-bit key, 1 in 256 keys is weak in the sense that it has 2 equivalent keys. An efficient algorithm is proposed to construct these weak keys and the corresponding equivalent keys. If a weak key is used, it can be recovered by exhaustive search trying ...

A knot (or link) diagram is said to be everywhere equivalent if all the diagrams obtained by switching one crossing represent the same knot (or link). We classify such diagrams of a closed 3-braid.

some of the difficulties and misunderstandings that happen in accounting theory, practice, regulation and education are grounded in language and linguistics. as an illustration of this the persian equivalent of 'accounting' is linguistically analysed to reveal how a mistranslation may cause difficulties in understanding and improving iranian accounting. this paper shows how hesaabdaar...

The coefficient of determination, R, is widely used as a measure of fit for model selection and variable selection. However, R does not offer any insight about the quality of the predicted values or the potential influence of particular observed values on the predicted values. In regression analysis, statistical procedures such as t test, F test, and prediction intervals provide insight into th...
