Interestingly enough, they are based on the same arithmetic operations, and the same design philosophy allows one to design lightweight coprocessors for hashing and encryption. The key element of our approach is to take advantage of the parallelism of the algorithms considered in this work to deeply pipeline our Arithmetic and Logic Units, and to avoid data dependencies by interleaving independent tasks. We show for instance that a fully autonomous implementation of BLAKE and ChaCha on a Xilinx Virtex-6 device occupies 144 slices and three memory blocks, and achieves competitive throughputs. In order to offer the same features, a coprocessor implementing Skein and Threefish requires a substantial higher slice count.","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/121196"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEEE Circuits and Systems Society"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1109/TCSI.2013.2278385","subitem_relation_type_select":"DOI"}}]},"item_5_relation_40":{"attribute_name":"部分である","attribute_value_mlt":[{"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://eprint.iacr.org/eprint-bin/print.pl","subitem_relation_type_select":"URI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2013 IEEE.
