Stream Ciphers Analysis Methods

Two Generic Methods of Analyzing Stream Ciphers

Since the security analysis against stream ciphers becomes more difficult nowadays, it is urgent and significant to propose new generic methods. In this work, we introduce guess-and-determine techniques to two traditional analysis methods and make the new approaches methodological for generalization. We show the power of the new methods by analyzing two stream ciphers: Grain-v1 and ACORN. Grain...

Fault Analysis of Stream Ciphers

A fault attack is a powerful cryptanalytic tool which can be applied to many types of cryptosystems which are not vulnerable to direct attacks. The research literature contains many examples of fault attacks on public key cryptosystems and block ciphers, but surprisingly we could not find any systematic study of the applicability of fault attacks to stream ciphers. Our goal in this paper is to ...

Analysis of Lightweight Stream Ciphers

Stream ciphers are fast cryptographic primitives to provide confidentiality of electronically transmitted data. They can be very suitable in environments with restricted resources, such as mobile devices or embedded systems. Practical examples are cell phones, RFID transponders, smart cards or devices in sensor networks. Besides efficiency, security is the most important property of a stream ci...

Stream ciphers and the eSTREAM project

Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers.
