Encryption Module (Defence)

In this project we developed a configurable software encryption module. The module was used to encrypt data on a mobile device over a bandwidth-limited medium, so efficiency in terms of data format and power consumption were decisive requirements. We implemented a software component that enabled segmentation into secured and public areas as well as the protection of data in the public area.

The solution used a certified cryptographic library to implement the low-level encryption algorithms as well as a smartcard with PIN for key generation and management. We also produced the documentation required for successful certification comparable to Common Criteria EAL4.
