Critical systems must be both safe from inadvertent harm and secure from malicious actors. However, safety and security practices have historically evolved in isolation. Safety-critical systems, such as aircraft and medical devices, have long been analyzed for problems that could arise accidentally or from component degradation.

They have been considered standalone systems, however, that were impervious to security issues because they had no networking capabilities.

What Is A Digital Signature?
  • A digital signature is a cryptographic mechanism used to verify the authenticity and integrity of digital data.
  • We may consider it as a digital version of the ordinary handwritten signatures, but with higher levels of complexity and security.
  • In simple terms, we may describe a digital signature as a code that is attached to a message or document. After generated, the code acts as proof that the message hasn’t been tampered with along its way from sender to receiver.
