PRESENT is a lightweight block cipher, developed by the Orange Labs (France), Ruhr University Bochum (Germany) and the Technical University of Denmark in 2007. PRESENT is designed by Andrey Bogdanov, Lars R. Knudsen, Gregor Leander, Christof Paar, Axel Poschmann, Matthew J. B. Robshaw, Yannick Seurin, and C. Vikkelsoe. The algorithm is notable for its compact size (about 2.5 times smaller than AES).
The block size is 64 bits and the key size can be 80 bit or 128 bit. The non-linear layer is based on a single 4-bit S-box which was designed with hardware optimizations in mind. PRESENT is intended to be used in situations where low-power consumption and high chip efficiency is desired. The International Organization for Standardization and the International Electrotechnical Commission included PRESENT in the new international standard for lightweight cryptographic methods.
By design all block ciphers with a block size of 64 bit can have problems with block collisions if they are used with large amounts of data. Therefore, implementations need to make sure that the amount of data encrypted with the same key is limited and rekeying is properly implemented.
