We consider the problem of efficiently designing sets (codes) of equal-length DNA strings (words) that satisfy certain combinatorial constraints. This problem has numerous motivati...

At TCC 2005, Backes and Cachin proposed a new and very strong notion of security for public key steganography: secrecy against adaptive chosen covertext attack (SS-CCA); and posed ...

We study a clean machine model for external memory and stream processing. We show that the number of scans of the external data induces a strict hierarchy (as long as work space is...
