High-rate codes with sublinear-time decoding
Locally decodable codes are error-correcting codes that admit efficient decoding algorithms; any bit of the original message can be recovered by looking at only a small number of ...

Length-Limited Variable-to-Variable Length Codes For High-Performance Entropy Coding
Arithmetic coding achieves a superior coding rate when encoding a binary source, but its lack of speed makes it an inferior choice when true high? performance encoding is needed. ...

Design and performance of a novel low-density parity-check code for distributed video coding
Low-density parity-check (LDPC) codes are nowadays one of the hottest topics in coding theory, notably due to their advantages in terms of bit error rate performance and low compl...

Cipher Instruction Search Attack on the Bus-Encryption Security Microcontroller DS5002FP
Abstract—A widely used bus-encryption microprocessor is vulnerable to a new practical attack. This type of processor decrypts onthe-fly while fetching code and data, which are st...
