History of the bicycle boneshaker, the front wheel enlarging to enable higher speeds (limited by the inside leg measurement of the rider), the rear wheel shrinking and the frame being made lighter. Frenchman Eugène Meyer is now regarded as the father of the high bicycle by the ICHC in place of James Starley. Meyer invented the wire-spoke tension wheel in 1869 and produced a classic high bicycle design until the 1880s. James Starley in Coventry added the tangent spokes and the mounting step to his famous bicycle named "Ariel." He is regarded as the father of the British cycling industry. Ball bearings, solid rubber
Block cipher mode of operation since each block gets decrypted in exactly the same way. Ehrsam, Meyer, Smith and Tuchman invented the Cipher Block Chaining (CBC) mode of operation in 1976. In CBC mode, each block of plaintext is XORed with the previous ciphertext block before being encrypted. This way, each ciphertext block depends on all plaintext blocks processed up to that point. To make each message unique, an initialization vector must be used in the first block. If the first block has index 1, the mathematical formula for CBC encryption is while the mathematical formula for CBC decryption is CBC has been the most
