Optimal and Near-Optimal Partner Selection Algorithms in Cooperative
We obtain the jointly optimal power allocation and partner selection policies, that maximize the sum rate of a cooperative OFDMA system with mutually cooperating pairs of users. We show that the power allocation and partner ...
Cryptanalysis of Fridrich\'s chaotic image encryption
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010-05)
We cryptanalyze Fridrich's chaotic image encryption algorithm. We show that the algebraic weaknesses of the algorithm make it vulnerable against chosen-ciphertext attacks. We propose an attack that reveals the secret ...
