Sentence examples for using a block cipher from inspiring English sources

Before the public can be comfortable with using a block cipher, it needs to gain public trust on its level of security.

Encrypting the encoded image data on a bitstream level using a block or stream cipher usually breaks the format compliance of the resulting file.

SM3 [12] is the Chinese cryptographic hash standard which was announced in 2010 and designed by Wang et al. It is based on the Merkle Damgård design and its compression function can be seen as a block cipher used in Davies Meyer mode.

The proposed method uses a simple block cipher based on matrix multiplication to encrypt images which are then sent to all users via multicast transmission.

In general, there are two techniques to apply a DFA attack on a block cipher.

A block cipher breaks the plaintext into blocks of the same size for encryption using a common key: the block size for a Playfair cipher is two letters, and for the DES (described in the section History of cryptology: The Data Encryption Standard and the Advanced Encryption Standard) used in electronic codebook mode it is 64 bits of binary-encoded plaintext.

HIGHT is a block cipher designed in Korea with the involvement of Korea Information Security Agency.

Clearly, the most important attribute of a block cipher is its security.

We expect that the matrix method developed in this article will be useful for evaluating the security of block ciphers against impossible differential cryptanalysis, especially when one tries to design a block cipher with a secure structure.
