WebBlock ciphers are one of the most prominently used cryptographic primitives and probably account for the largest portion of data encrypted today. This was facilitated by the introduction of Rijndael as the Advanced Encryption Standard (AES) [2], which was a major step forward in the eld of block cipher design. Not Webblocks of a previously determined, ﬁxed size (often 64 or 128 bits), while stream ciphers encrypt and decrypt the plain text one bit at a time. A key idea in the design of block ciphers is to use a simple transformation called round function that operates on the block multiple times (see Figure 1.1 for a schematic example). Those round boc giay ep plastic
