Study of the Invariant Coset Attack on PRINTcipher: More Weak Keys With Practical Key Recovery
Lightweight cryptography gained its importance due to emergence of many applications that involve using small and resource constraint devices like RFID tags, smart cards, and sensors. Conventional cryptographic algorithms turned out to be too massive to be implemented on such devices. Therefore the need for new cryptographic primitives arose in the community. In particular, the whole arsenal of lightweight block ciphers has been developed in recent years to satisfy the needs for secure usage of small devices. The block cipher PRESENT is one outstanding example that gained popularity. Other block ciphers, such as KATAN and KTANTAN family, LED block cipher and many others were presented recently.
