3. Bazeries Cipher • Cylinders such as the Wheel cipher use a set of wheels with the alphabet in different, random orders around each wheel • Bazeries developed one in 1891 with 20 cylinders • a b c d e f g h i j k l m n o p q r s t u v x y z • b c d f g h j k l m n p q r s t v x z a e i o u y • a e b c d f g h i o j k l m n p u y q r s t v x z • z y x v u t s r q p o n m l k j i h g f e d c b a • y u z x v t s r o i q p n m l k e a j h g f d c b • z x v t s r q p n m l k j h g f d c b y u o i e a • a l o n s e f t d p r i j u g v b c h k m q x y z • b i e n h u r x l s p a v d t o y m c f g j k q z • c h a r y b d e t s l f g i j k m n o p q u v x z • d i e u p r o t g l a f n c b h j k m q s v x y z • e v i t z l s c o u r a n d b f g h j k m p q x y • f o r m e z l s a i c u x b d g h j k n p q t v y • g l o i r e m t d n s a u x b c f h j k p q v y z • h o n e u r t p a i b c d f g j k l m q s v x y z • i n s t r u e z l a j b c d f g h k m o p q v x y • j a i m e l o g n f r t h u b c d k p q s v x y z • k y r i e l s o n a b c d f g h j m p q t u v x z • l h o m e p r s t d i u a b c f g j k n q v x y z • m o n t e z a c h v l b d f g i j k p q r s u x y • 20 n o u s t e l a c f b d g h i j k m p q r v x y z
