Bit-Interleaved Coded Modulation with Mismatched Decoding Metrics
Bit-interleaved coded modulation (BICM) has become the de facto coding standard for communication systems. Recently, BICM has been cast as a mismatched decoding scheme due to the ...

Unidirectional Chosen-Ciphertext Secure Proxy Re-Encryption
Abstract. In 1998, Blaze, Bleumer, and Strauss proposed a cryptographic primitive called proxy re-encryption, in which a proxy transforms – without seeing the corresponding plain...
