    Aplicabilidade da encriptação especulativa em CPUs multicore para sistema de arquivo no espaço de usuário

    Due to the constantly growing need for security and efficiency
    in accessing stored data, there is also constant search for better
    storage media that bring this warranty. Previous research has led to
    the creation of libraries for parallel processing on GPU to perform
    speculative encryption of data. The efficiency of this method was
    demonstrated in its use in cryptographic file systems. However, the
    applicability and effectiveness of these methods using only CPUs

    remained an open problem. In order to test the feasibility of specu-
    lative cryptography in computing environments with CPUs only,

    this work presents a library version for speculative encryption with
    parallel processing on multicore processors and its adaptation to the

    EncFS++ file system in user space. The tests carried out show con-
    siderable increases in throughput in the most varied environments,

    both physical and virtual machines, using CPUs that may or may
    not support the AES-NI instruction set for encryption acceleration.
