1 We describe a side-channel attack on a substitution block, which is usually implemented as a table lookup operation. In particular, we have investigated smartcard implementations...
Abstract. Automated image interpretation is an important task in numerous applications ranging from security systems to natural resource inventorization based on remote-sensing. Re...
The emergence of new information and communication system technologies allow the appearance of new techniques of data processing. Thus, it is increasingly difficult to user to find...
Field Programmable Gate Arrays (FPGAs) are becoming increasingly popular, especially for rapid prototyping. For implementations of cryptographic algorithms, not only the speed and ...
A classical construction of stream ciphers is to combine several LFSRs and a highly non-linear Boolean function f. Their security is usually analysed in terms of correlation attack...
