Cascade Jump Controlled Sequence Generator and Pomaranch Stream Cipher
نویسندگان
چکیده
Jump registers were recently proposed [SASC04] as building blocks for stream ciphers. In this paper a construction based on these principles is described. The proposed encryption primitive is a synchronous stream cipher accommodating a key of 128 bits and an IV of 64 up to 162 bits, or an 80-bit key and 32 to 108 bit IV. Version 3 comes as a final submission for the second phase of the eSTREAM project. The stream cipher is particularly designed to resist side-channel attacks and can be efficiently implemented in hardware for a wide range of target processes and platforms.

Pomaranch - Design and Analysis of a Family of Stream Ciphers ∗
Pomaranch is a synchronous, hardware-oriented stream cipher submitted to eSTREAM, the ECRYPT Stream Cipher Project. The cipher is designed as a cascade clock-controlled key-stream generator built on jump registers. This paper presents a discussion over the attacks on Pomaranch discovered so far. Particular focus is made on a new inherent property of jump registers that allows to construct their...
متن کاملCryptanalysis of Pomaranch
Pomaranch [3] is a synchronous stream cipher submitted to eSTREAM, the ECRYPT Stream Cipher Project. The cipher is constructed as a cascade clock control sequence generator, which is based on the notion of jump registers. In this paper we present an attack which exploits the cipher's initialization procedure to recover the 128-bit secret key. The attack requires around 2 computations. An improv...
متن کاملCryptanalysis of Pomaranch (CJCSG)
Pomaranch is a synchronous stream cipher submitted to eSTREAM, the ECRYPT Stream Cipher Project. It uses 128-bit keys and IVs with different lengths. The cipher is constructed as a cascade clock control sequence generator, which is based on the notion of jump registers. Each jump register can be considered as a non-autonomous finite state machine which the input sequence is called jump control ...
متن کاملCountering the Correlation Attack on Pomaranch
A recent key-recovery attack on Pomaranch stream cipher was built due to the spotted biases in the distribution of certain linear relations in the output sequence of a Jump Register Section. All the relations and corresponding biases were found by computer experiments. The suggested attack has the complexity O(2) and requires 2 bits of the key-stream. In this paper we give theoretical reasons e...
متن کاملCascade Jump Controlled Sequence Generator (CJCSG)
Jumping LFSRs have recently been proposed [SASC04] as building blocks for stream ciphers. In this paper a construction based on these principles is described. The proposed encryption primitive is the key stream generator part of a synchronous stream cipher accommodating a key of 128 bits and an IV of 64 up till 112 bits. A number of cryptanalytic attacks are considered, leading to the conclusio...
