Parallelizable Rate-1 Authenticated Encryption from Pseudorandom Functions [chapter]

Kazuhiko Minematsu
2014 Lecture Notes in Computer Science  
When it is realized with a blockcipher, it requires one blockcipher call to process one input block (i.e. rate-1), and uses the encryption function of the blockcipher for both encryption and decryption  ...  This paper proposes a new scheme for authenticated encryption (AE) which is typically realized as a blockcipher mode of operation.  ...  The author would like to thank anonymous reviewers for careful reading and invaluable suggestions, which greatly improved the presentation of the paper.  ...

CLOC: Authenticated Encryption for Short Input [chapter]

Tetsu Iwata, Kazuhiko Minematsu, Jian Guo, Sumio Morioka
2015 Lecture Notes in Computer Science  
CLOC uses a variant of CFB mode in its encryption part and a variant of CBC MAC in the authentication part.  ...  We define and analyze the security of a blockcipher mode of operation, CLOC, for provably secure authenticated encryption with associated data.  ...  We have (18) = 1/2 n from the randomness of HASH4 ′′ , and (19) ≤ mm ′ /2 n + max{m, m ′ }/2 n from Lemma 5. We now evaluate the probability of the bad event.  ...

Anne Canteaut, Sébastien Duval, Gaëtan Leurent, María Naya-Plasencia, Léo Perrin, Thomas Pornin, André Schrottenloher
2020 IACR Transactions on Symmetric Cryptology  
In this paper, we specify a new block cipher, Saturnin, and its usage in different modes to provide hashing and authenticated encryption in such a way that we can rigorously argue its security in the post-quantum  ...  A simple answer to this problem is a compromise on the security level: through a weaker round function or a smaller number of rounds, the security level can be decreased in order to cheapen the implementation  ...  They are also particularly grateful to Xavier Bonnetain for very helpful discussions and comments, and in particular for an invaluable remark detecting a weakness on a preliminary version of Saturnin.  ...
