Power Analysis by Microngroup
Power analysis is one of Micron Group’s many specialist offerings. Micron Group’s technicians and engineers assist clients by installing high tech power analysers to electrical switchboards and equipment.
Installed analysers gather critical electrical data such as voltage, current flow, harmonics, power factor, frequency, and energy used over time, (whether it be minutes, hours, days or even months) helping to diagnose hard to find problems. Power analysers are also used to simply log power usage for comparative analysis. See More Micron Group Specialised Services
Simple power analysis (SPA) is a side-channel attack which involves visual examination of graphs of the current used by a device over time. Variations in power consumption occur as the device performs different operations. For example, different instructions performed by a microprocessor will have differing power consumption profiles. As a result, in a power trace from a smart card performing a DES encryption, the sixteen rounds can be seen clearly. Similarly, squaring and multiplication operations in RSA implementations can often be distinguished, enabling an adversary to compute the secret key. Even if the magnitude of the variations in power consumption are small, standard digital oscilloscopes can easily show the data-induced variations.
Frequency filters and averaging functions (such as those built into oscilloscopes) are often used to filter out high-frequency components.
