Pillars of Non repudiation
- Verification: Nonrepudiation is ensuring that users are genuinely who they claim to be, using methods like passwords, usernames, digital certificates, and security tokens.
- Reliability: Nonrepudiation encourages that information is always available on time and performs well whenever it’s needed.
- Privacy: Limiting access to sensitive data, such as personally identifiable information and confidential corporate data.
- Non-denial: This prohibits people from being able to retract their actions because the system records each action they perform.
What is Non Repudiation?
Non-repudiation is the ability to prevent an electronic message or transaction that someone cannot deny the validity of something. It is a legal concept that’s mostly used in information security and refers to a service, which provides a reason for the origin and integrity of data. In other words, non-repudiation makes it very challenging to strongly deny who/where a message comes from, as well as the authenticity and integrity of that message.
It authenticates both the sender and the recipient of the information. It is irrefutable for both parties that this was how the communication took place. This security feature is essential to preserving dependability and confidence throughout a range of procedures.
