Abstract

The Kalyna block cipher has recently been selected as the Ukranian encryption standard in June, 2015. It supports block sizes of 128 bit, 256 bit, and 512 bit, and key sizes of 128 bit, 256 bit, and 512 bit. Among them, the key size can be equal to or twice as the block length, denoted by Kalyna-b/2b. In order to apply it safely in the real systems, the researchers should evaluate the security of Kalyna against the meet-in-the-middle attack which is one of the currently popular attacks. This paper researched the key schedule of Kalyna-128/256 to obtain some linear relationships among round keys. Based on them, it constructed four 6-round distinguishers by using multisets, differential enumerations and key-dependent sieve techniques. Through appending one round at its top and three rounds at its bottom, it mounted a meet-in-the-middle attack on 10-round Kalyna-128/256. In order to reduce the time complexity of online phase, it applied the time-memory tradeoff technique. Finally, the data, time and memory complexities of attack are 2111 chosen plaintexts, 2238.63 8-round encryptions and 2222 128 bit blocks, respectively. The results show that compared with the previously best known meet-in-the-middle attack on 10-round Kalyna-128/256, the data, time and memory complexities are reduced by 24 times, 214.67 times and 226.8 times, respectively.
