libpresent

This small library implements the PRESENT lightweight block cipher. The algorithm was first presented in this paper. Although the cipher is designed to be implemented directly on hardware, this project aims to provide it in software, which can be used e.g. for testing purposes.

This project is independent of the original paper and not affiliated with the authors of that paper in any way.

Security

The algorithm should, according to the original authors, not be used in environments where a high security level is required. This is caused by the high priority on performance, which entails relatively small keys (80 bit). This implementation, however, should not be used in any environment where security is important, because I do not guarantee that the algorithm is implemented in a secure manner (it most likely is not).
