Towards achieving the new notions of plaintext awareness, we show that a scheme due to Damg?rd [12], denoted DEG, and the “l(fā)ite” version of the Cramer-Shoup

After giving the basic definitions, we prove that the known equivalence relations can be seen as particular cases of the proposed generalized relationship and th

Mo?se Namer,Michel Héry,Joseph Gligorovt reason seems the lack of research on building a solid mathematical foundation for the use of infinite groups in cryptography. As a first step for this line of research, this paper pays attention to a property, the so-called right-invariance, which makes finite groups so convenient in cryptography,
