A tubular pin tumbler lock, also known as a circle pin tumbler lock, radial lock, or the trademark Ace lock popularized by manufacturer Chicago Lock Company since 1933, is a variety of pin tumbler lock in which a number of pins are arranged in a circular pattern, and the corresponding key is tubular or cylindrical in shape. Most locks use ...

In cryptography, a round or round function is a basic transformation that is repeated multiple times inside the algorithm. Splitting a large algorithmic function into rounds simplifies both implementation and cryptanalysis .

One of the \(Nr+1\) arrays of four words that are derived from the block cipher key using the key expansion routine; each round key is an input to an instance of ADDROUNDKEY() in the AES block cipher.

So, to answer your question: Round key 9 is the first which gets XORed with the subbytes result, but before that (at the very start of decryption), round key 10 gets XORed with the ciphertext. As we have to use the same subkeys for encryption and decryption, you'll have to do the same (or equivalent) key schedule, too.

It was clear that a round key is better due to the fact that it distributed the load over a wider area and also prevented splitting of drive shaft couplings. Is there anyone aware of this test or know for sure what the answer might be?

Jan 13, 2015 · The round key is derived from the key and adding it is what makes the algorithm a block cipher (AKA: a keyed permutation) rather than just a permutation. In the image below you can see a typical block cipher.
