Results Context Investigated KDM Security in the context of Hybrid Encryption: § Present a generic composition theorem for adaptive, KDM-secure hybrid encryption in the Random Oracle model. § Proof method incorporates non-standard techniques that could be applicable in a wider context. Key-Dependent Message (KDM) Security involves an environment where the(More)
We construct secret-key encryption (SKE) schemes that are secure against related-key attacks and in the presence of key-dependent messages (RKA-KDM secure). We emphasize that RKA-KDM security is not merely the conjunction of individual security properties, but covers attacks in which ciphertexts of key-dependent messages under related keys are available.(More)

Advanced manufacturing encompasses the wide range of processes that consist of " 3D printing " of metallic materials. One such method is Electron Beam Melting (EBM), a modern build technology that offers significant potential for lean manufacture and a capability to produce fully dense near-net shaped components. However, the manufacture of intricate(More)
