Access control in ultra-large-scale systems using a data-centric middleware

S. Shokrollahi; F. Shams; J. Esmaeili

Volume 6, Issue 1 , January 2014, Pages 3-22


    The primary characteristic of an Ultra-Large-Scale (ULS) system is ultra-large size on any related dimension. A ULS system is generally considered as a system-of-systems with heterogeneous nodes and autonomous domains. As the size of a system-of-systems grows, and interoperability demand between ...  Read More

Total break of Zorro using linear and differential attacks

Sh. Rasoolzadeh; Z. Ahmadian; M. Salmasizadeh; M. R. Aref

Volume 6, Issue 1 , January 2014, Pages 23-34


  An AES-like lightweight block cipher, namely Zorro, was proposed in CHES 2013. While it has a 16-byte state, it uses only 4 S-Boxes per round. This weak nonlinearity was widely criticized, insofar as it has been directly exploited in all the attacks on Zorro reported by now, including the weak key, reduced ...  Read More
