Contents:IJES is a refereed international journal providing an international forum to report, discuss and exchange experimental or theoretical results, novel designs, work-in-progress, experience, case studies, and trend-setting ideas. Papers should be of a quality that represents the latest advances in embedded systems in time-to-market, cost, code size, weight, testability, power, real-time behaviour, and stimulating future trends.

Biclique cryptanalysis is a typical attack through finding a biclique which is a type of bipartite diagram to reduce the computational complexity. By investigating the subkey distribution and the encryption structure, we find out a weakness in the key schedule of Piccolo-80. A 6-round biclique is constructed for Piccolo-80 and a 7-round biclique for Piccolo-128. Then a full round biclique cryptanalysis of Piccolo is presented. The results of the attacks are with data complexity of 2 40 and 2 24 chosen ciphertexts and with computational complexity of 2 79.22 and 2 127.14 , respectively. They are superior to other known results of biclique cryptanalytic on Piccolo.
