Group Key Establishment: Adding Perfect Forward?Secrecy at the Cost of One Roundnfrastructure. Building on a secure unauthenticated 1-round 2-party key establishment . with perfect forward secrecy as auxiliary input, . is transformed into an authenticated group key establishment protocol with perfect forward secrecy and with one more round than ..

Strong Privacy for RFID Systems from Plaintext-Aware Encryptionr proposes a slight change in the definition of privacy from the Vaudenay model (Asiacrypt 2007). Then, we show that by adding a plaintext-aware assumption on the public-key cryptosystem, the proposed protocol always achieves strong privacy with our new definitions.

is the complexity of solving a sparse quadratic equation system on 56 unknown key bits. Furthermore we provide a new approach to solving the above sparse quadratic equation system, which reduces the complexity . to a very small constant. Finally we do an entire experiment on a PC and recover all bits of a random key in a few seconds.

The multiple transmission attack can be further improved with a linearization technique to that only . times of encryptions are required to recover the message. An open problem related to the message recovery attack using only one cipehertext is discussed.
