We observe a natural generalisation of the ate and twisted ate pairings, which allow for performance improvements in non standard applications of pairings to cryptography like composite group orders. We also give a performance comparison of our pairings and the Tate, ate and twisted ate pairings for certain polynomial families based on operation count(More)
This paper shows the great potential of lightweight cryptography in fast and timing-attack resistant software implementations in cloud computing by exploiting bitslice implementation. This is demonstrated by bitslice implementations of the PRESENT and Piccolo lightweight block ciphers. In particular, bitsliced PRESENT-80/128 achieves 4.73 cycles/byte and(More)
