# Is the scytale a Block Cipher?

Can we consider the Scytale a block cipher ? If yes why ? Can you tell me ?

• A block cipher consists of two algorithms Enc and Dec that operate on a fixed block size $n$-bit with a key of size $k$-bit to output $n$-bit size. $Dec = Enc^{01}$ – kelalaka Nov 30 '19 at 19:13
