Constructing Variable-Length PRPs and SPRPs from Fixed-Length PRPs [PDF]

, 2008
We create variable-length pseudorandom permutations (PRPs) and strong PRPs (SPRPs) accepting any input length chosen from the range of b to 2b bits from fixed-length, b-bit PRPs.

Tweakable ForkCipher from Ideal Block Cipher

IACR Communications in Cryptology
In ASIACRYPT 2019, Andreeva et al. introduced a new symmetric key primitive called the forkcipher, designed for lightweight applications handling short messages. A forkcipher is a keyed function with a public tweak, featuring fixed-length input and fixed-length (expanding) output.

Cryptanalysis of Full-Round BipBip

IACR Transactions on Symmetric Cryptology
BipBip is a low-latency tweakable block cipher proposed by Belkheyar et al. in 2023. It was designed for pointer encryption inside a new memory safety mechanism called Cryptographic Capability Computing (C3). BipBip encrypts blocks of 24 bits using a 40-

Elastic Block Ciphers: Method, Security and Instantiations [PDF]

, 2009
We introduce the concept of an elastic block cipher which refers to stretching the supported block size of a block cipher to any length up to twice the original block size while incurring a computational workload that is proportional to the block size ...
