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...
متن کاملSome Results on Distinguishing Attacks on Stream Ciphers
Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. The thesis provides a general introduction to cryptology, explains the basic concepts, gives an overview of various cryptographic primitives and discusses a number of d...
متن کاملSome Words on Cryptanalysis of Stream Ciphers
I the world of cryptography, stream ciphers are known as primitives used to ensure privacy over a communication channel. One common way to build a stream cipher is to use a keystream generator to produce a pseudorandom sequence of symbols. In such algorithms, the ciphertext is the sum of the keystream and the plaintext, resembling the one-time pad principal. Although the idea behind stream ciph...
متن کاملOn Lightweight Stream Ciphers with Shorter Internal States
To be resistant against certain time-memory-data-tradeoff (TMDTO) attacks, a common rule of thumb says that the internal state size of a stream cipher should be at least twice the security parameter. As memory gates are usually the most area and power consuming components, this implies a sever limitation with respect to possible lightweight implementations. In this work, we revisit this rule. W...
متن کاملNew Results on Cryptanalysis of Stream Ciphers
Stream ciphers are cryptographic primitives that ensure the confidentiality of communications. In this thesis, we study several attacks on stream ciphers. For practical applications, the candidates of stream ciphers of NESSIE and eSTREAM projects are scrutinized. Firstly, the algebraic attacks on SOBER-t32 and SOBER-t16 stream ciphers are performed under the assumption that the stuttering phase...
