Length-Preserving Encryption Based on Single-Key Tweakable Block Cipher
2018We present a Single-key Length Doubler built on an n-bit Tweakable block cipher (SLDT), which is a length-preserving cipher on the strings with bit length in integer interval \(\left[ n, n+1, \ldots , 2n-1\right] \). SLDT is mainly motivated to reduce the key material size of a length doubler proposed by Chen et al. at FSE2018, since the key management

ZMAC: A Fast Tweakable Block Cipher Mode for Highly Secure Message Authentication
2017We propose a new mode of operation called \(\mathsf {ZMAC}\) allowing to construct a (stateless and deterministic) message authentication code (MAC) from a tweakable block cipher (TBC). When using a TBC with n-bit blocks and t-bit tweaks, our construction provides security (as a variable-input-length PRF) beyond the birthday bound with respect to the ...
