Software architecture is important for large systems in which it is the main means for, among other things, controlling complexity. Current ideas on software architec-tures were not available more than ten years ago. Software developed at that time has been deteriorating from an architectural point of view over the years, as a result of adaptations made in(More)
SUMMARY Software architecture plays a vital role in the development (and hence maintenance) of large complex systems (containing millions of lines of code) with a long lifetime. It is therefore required that the software architecture is also maintained, i.e., sufficiently documented, clearly communicated, and explicitly controlled during its life-cycle. In(More)
— Software architecture plays a vital role in the development (and hence maintenance) of large complex systems with a long lifetime. It is therefore required that the software architecture is also maintained, i.e. sufficiently documented, clearly communicated, and explicitly controlled. In our experience, these requirements cannot be met without appropriate(More)
Recovery of data stored in a fault-tolerant and secure way requires encryption and / or decryption of data with secret cryptographic functions, for which a group of processors should be responsible. For this purpose, the here-introduced distributed cryptographic function application protocols (DCFAPs) can be applied. DCFAPs are executed on a set, N , of N(More)
