Homomorphic encryption features and specs

• Data Privacy Preservation
  Homomorphic encryption allows computations on encrypted data without needing to decrypt it first, ensuring data remains confidential throughout the processing phase.
• Enhanced Security
  By allowing processing to occur on encrypted data, it minimizes the risk of data exposure during transactions or computations, protecting against data breaches and unauthorized access.
• Compliance Facilitation
  This encryption technique can aid in meeting data protection regulations and privacy laws by ensuring that sensitive data is always handled in an encrypted form, thus simplifying compliance with data privacy standards.
• Enabling Cloud Computing
  Users can safely utilize cloud-based services to perform computations on their sensitive data without giving the cloud provider access to the raw, unencrypted data.

Possible disadvantages of Homomorphic encryption

• Performance Overhead
  Homomorphic encryption is computationally intensive, resulting in slower processing times compared to operations on unencrypted data. This can limit its practicality for time-sensitive applications.
• Complex Implementation
  The encryption and decryption processes are more complex to implement, requiring specialized knowledge and complicating development processes.
• Larger Data Sizes
  Encrypted data can be significantly larger than its plaintext form, which can lead to increased storage requirements and higher data transmission costs.
• Limited Supported Operations
  While research is ongoing, currently only certain types of calculations can be performed on encrypted data, which may restrict its applicability for some use cases.

KETS Quantum Key Distribution features and specs

• Unconditional Security
  KETS Quantum Key Distribution offers security based on the principles of quantum mechanics, which cannot be broken by classical computing techniques, making it more secure against potential future advances in computing, such as quantum computers.
• Eavesdropping Detection
  One of the key benefits of quantum key distribution is its ability to detect eavesdropping. Any attempt by a third party to intercept the keys will introduce anomalies, alerting the parties involved.
• Long-Term Security
  The security of QKD protocols is not compromised by technological advancements, providing a future-proof solution for securing sensitive communications.

Possible disadvantages of KETS Quantum Key Distribution

• Implementation Cost
  The technology required for KETS QKD is currently expensive, involving specialized equipment and systems, which makes it costly for widespread adoption.
• Limited Range
  QKD currently has distance limitations due to the rate of photon loss over long distances, which necessitates the use of repeaters or satellite systems.
• Infrastructure Requirements
  Implementing QKD requires significant changes or additions to existing communication infrastructure, which can be challenging and resource-intensive.
