On Design of Robust Lightweight Stream Cipher with Short Internal State
The stream cipher Sprout with a short internal state was proposed in FSE 2015. Although the construction guaranteed resistance to generic Time Memory Data Tradeoff attacks, there were some weaknesses in the design and the cipherwas completely broken. In this paperwe propose a family of stream ciphers LILLE in which the size of the internal state is half the size of the secret key. Our main goal...
متن کاملFruit-v2: Ultra-Lightweight Stream Cipher with Shorter Internal State
A few lightweight stream ciphers were introduced for hardware applications in the eSTREAM project. In FSE 2015, while presenting a new idea (i.e. the design of stream ciphers with the shorter internal state by using a secret key, not only in the initialization but also in the keystream generation), Sprout was proposed. Unfortunately, Sprout is insecure. Because Grain-v1 is the lightest cipher i...
متن کاملFruit: ultra-lightweight stream cipher with shorter internal state
In eSTREAM project, a few lightweight stream cipher for hardware was introduced (2008) and then in FSE 2015 Sprout was proposed. Sprout introduced a new idea, design of stream cipher with shorter internal state by using key not only in initialization but also in keystream generation, but it was insecure. Grain-v1 is almost the lightest secure cipher in world. Fruit stream cipher is successor of...
متن کاملStream Cipher Design based on Jumping Finite State Machines
This paper presents a new way of constructing binary cascade clock-controlled LFSR sequence generators as building blocks for stream ciphers. In these constructions the bottleneck of multiple clocking shift registers is removed, resulting in so called jump-controlled sequence generators, that operate in a single clock pulse and are most efficient to implement. The constructions make use of spec...
متن کاملcient Stream Cipher with Variable Internal
This paper presents an eecient stream cipher using an internal state with variable structure and evolution. Arbitrarily large internal states can be used in order to defeat brute-force guessing attacks without compromising the performance of cipher, and possibly improving it. Attacking is made even more complicated by dynamically chosing diierent topologies and evo-lutions for the cipher's inte...
