Title Industrial Control Systems Cybersecurity Initiative: Considerations for ICS/OT Monitoring Technologies with an Emphasis on Detection and Information Sharing Cryptography is widely used on the internet to help protect user-data and prevent eavesdropping. To ensure secrecy during transmission, many systems use private key cryptography to protect transmitted information. With public-key systems, one can maintain secrecy without a master key or a large number of keys. But, some algorithms like Bitlocker and Veracrypt are generally not private-public key cryptography. For example, Veracrypt uses a password hash to generate the si…
