Maximum Size of Aggregate

1.0K
The maximum size of aggregate is defined as the aperture of the sieve retaining 15 percent or more of the particles present in the aggregate sample. The aggregate's maximum size impacts the concrete's water requirement, workability, and strength. Larger aggregates reduce the surface area needing cement paste coverage, which can lower water needs, thereby allowing a decrease in the water-to-cement ratio when the desired workability and richness of the mix are to be maintained, which can...

  • Simulation-based analysis to evaluate the scheme's performance and implementability.

    • Main Results:

    • The proposed Fully homomorphic Encryption based Secure data Aggregation (FESA) scheme protects end-to-end data confidentiality.
    • FESA supports arbitrary aggregation operations on encrypted data.
    • Message Authentication Codes (MACs) effectively verify data integrity during aggregation and forwarding, detecting false data.
    • Simulation results demonstrate the implementability and effectiveness of FESA in LWSNs.
    • The scheme reduces transmitted data and network overhead compared to existing protocols.

    Conclusions:

    • FESA offers a robust solution for secure data aggregation in LWSNs, balancing security with efficiency.
    • The scheme enhances network lifetime by minimizing energy consumption through secure data aggregation.
    • Despite the computational overhead of FHE, FESA is practical for LWSN applications, providing significant improvements in data security and network performance.
