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 کاملA Survey on Lightweight Block Ciphers
Ubiquitous and pervasive computing are new era of computing and it needs lightweight cryptographic algorithms for security. Lightweight cryptography is used for resource constrained devices (which have limited memory, limited power and less processing capability) such as radio frequency identification (RFID) tags, contactless smart cards, wireless sensor network, health care devices and interne...
متن کاملAttacks in Stream Ciphers: A Survey
Nowadays there are different types of attacks in block and stream ciphers. In this work we will present some of the most used attacks on stream ciphers. We will present the newest techniques with an example of usage in a cipher, explain and comment. Previous we will
متن کاملA Survey of Cryptanalytic Attacks on Lightweight Block Ciphers
Lightweight block ciphers are used in applications where low power consumption is a requirement along with hardware area constraints regarding their implementation. Design of these ciphers demands an optimal tradeoff between computational efficiency and security. These ciphers being supportive in fast and secure transmission of data from one location to another are prone to several attacks that...
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...
