The World Is Not Enough: Another Look on Second-Order DPA
[chapter]
2010
Lecture Notes in Computer Science
Preserved Fulltext
Further, we also investigate the case of second-and third-order masking (i.e. using three and four shares to represent one value). ...
In other words, while a single distinguisher can be used to compare the susceptibility of different unprotected devices to first-order DPA, understanding second-order attacks requires to carefully investigate ...
Summarizing, these experiments confirm the "world is not enough" nature of second-order DPA. ...

In this study the masking countermeasure is tested with firstorder and higher-order SCAs on a fully-fledged DES. ...
This attack is based on a variance analysis of the observed power consumption and it clearly shows the vulnerabilities of masking countermeasures. ...
The second-order DPA as the one already presented in literature is hardly possible on a fully-fledged DES cryptoprocessor. ...

The DPA is able to recognize users' commands in natural language and transform it to the set of machine commands that can be used to control different 3rd-party application. ...
Another problem is that most of IoT devices are not capable of managing computationally intensive tasks, thus centralized control is required in order to build complex Automation system. ...
