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 ...

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...
