The advanced electronic signature is one of the standards outlined in eIDAS. For an electronic signature to be considered as advanced it must meet several requirements: [3][4] The signatory can be uniquely identified and linked to the signature. The signatory must have sole control of the signature creation data (typically a private key) that ...
AES key schedule. The Advanced Encryption Standard uses a key schedule to expand a short key into a number of separate round keys. The three AES variants have a different number of rounds. Each variant requires a separate 128-bit round key for each round plus one more. [note 1] The key schedule produces the needed round keys from the initial key.
The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]), [ 5 ] is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. [ 6 ]

First, the input is mapped to its multiplicative inverse in GF(2 8) = GF(2) [x]/(x 8 + x 4 + x 3 + x + 1), Rijndael's finite field. Zero, as the identity, is mapped to itself. This transformation is known as the Nyberg S-box after its inventor Kaisa Nyberg. [2] The multiplicative inverse is then transformed using the following affine ...
