What is non-repudiation in SAP BC-SEC - Security?

SAP Term: non-repudiation

• Component: BC-SEC

• Component Name: Security

• Description: The inability to deny having performed an action. This is important as electronic messages and documents can be easily copied or changed. Therefore, in case of dispute, we need a means to prove that the alleged person performed the action. Non-repudiation assures that the parties involved cannot deny what they have done. A non-repudiation service is able to prove that a person sent a message to another person. This is normally achieved by using a public-key technology.

• Key Concepts: 
  Non-repudiation is a security feature of SAP BC-SEC Security that ensures that a transaction cannot be denied by either party. It is used to protect the integrity of data and transactions, and to ensure that all parties involved in a transaction are held accountable for their actions. 
  
  How to use it: 
  Non-repudiation is enabled by using digital signatures, which are created using cryptographic algorithms. These digital signatures are used to authenticate the identity of the sender and receiver of a transaction, and to ensure that the data has not been tampered with. The digital signature also serves as proof that the sender has agreed to the terms of the transaction. 
  
  Tips & Tricks: 
  When using non-repudiation, it is important to ensure that all parties involved in the transaction have access to the necessary cryptographic algorithms and digital signature technology. Additionally, it is important to ensure that all parties involved in the transaction are aware of their responsibilities and obligations under the terms of the transaction.
