In this paper, we propose a 128-bit block cipher ARIA which is an involution substitution and permutation encryption network(SPN). We use the same S-boxes as Rijndael to eliminate ...

Motivated by emerging needs in online interactions, we define a new type of digital signature called a `Content Extraction Signature' (CES). A CES allows the owner, Bob, of a...

Although many strong cryptanalytic tools exploit weaknesses in the data-randomizinig part of a block cipher, relatively few general tools for cryptanalyzing on the other part, the ...

In this paper, we propose a multi-signature scheme, in which each signer can express her intention associating with the message to be signed. Signers' intentions mean a kind o...
