Turning Compression Schemes into Crypto-Systems
| Abstract: |
| Some techniques are presented turning several of the classical compression schemes into crypto-systems, not only reducing their space, but also securing their content by means of encryption based on the knowledge of a secret key. Only a single bit of the key is consumed at every encoding step, and the cumulative impact of applying these steps is shown to produce almost random output. Only the techniques are presented; security issues are deferred to future work. |
