This work discusses a Secure Computing Module (SCM) for
reconfigurable computing systems. Secure Computing (SC) provides a
protected and reliable computational environment, where data
security and protection against malicious attacks to the system is
assured. SC is strongly based on encryption algorithms and on the
attestation of the executed functions. The use of SC on
reconfigurable devices has the advantage of being highly adaptable
to the application and the user requirements, while providing high
performances. Moreover, it is adaptable to new algorithms,
protocols, and threats. In work, high performance cryptographic
units for symmetric encryption and hash functions are presented in
order to achieve a high performance SCM. A method to attest
dynamically reconfigured hardware structures is also proposed,
without penalizing the performance of the SCM. The presented
attestation mechanism allows the configuration bitstreams to be
stored in unsecured locations, such as on an external memory or the
internet, without posing a security threat. Overall, this
dissertation demonstrates the applicability and identifies the main
advantages of implementing SC on reconfigurable systems.
