The operation of the AES algorithm is shown inFigure 36-2. The encryption step uses a key that converts the data into an unreadable ciphertext, and then the decryption step uses the same key to convert the ciphertext back into the original data. This type of key is asymmetric key...

The AES encryption and decryption algorithms use a key schedule generated from the seed key array of bytes. The AES specification refers to this as the KeyExpansion routine. Generating, in essence, multiple keys from an initial key instead of using a single key greatly increases the diffusion of...

// The IV may be null, but supplying a random IV increases security. // The IV is not a secret like the key is. // You can transmit the IV (w/o encryption) alongside the ciphertext. var iv = WinRTCrypto.CryptographicBuffer.GenerateRandom(provider.BlockLength); byte[] cipherText = ...

This paper presents an interleaved-bitslice AES encryption and decryption with massive-parallel mobile embedded processor. Recent mobile devices need to apply private-information secure technology, such as cipher processing, to prevent the leakage of personal information. However, this adds to the produc...
