Threshold Encryption into Multiple Ciphertexts
We propose (T, N) multi-ciphertext scheme for symmetric encryption. The scheme encrypts a message into N distinct ciphertexts. The knowledge of the symmetric key allows decryption ...

Online Ciphers from Tweakable Blockciphers
Abstract. Online ciphers are deterministic length-preserving permutations EK : ({0, 1}n )+ → ({0, 1}n )+ where the i-th block of ciphertext depends only on the first i blocks of...
