What is a lack of trust and non-repudiation in a PKI?

Lack of trust and non-repudiation in a PKI refers to a situation where the system cannot establish trust between parties and provide evidence of the authenticity of digital certificates and transactions.

Lack of trust occurs when the PKI system is not configured correctly, has security weaknesses, or is not widely adopted.

This can lead to situations where the parties involved in a transaction do not have confidence in the authenticity of the digital certificates being used and are, therefore, unwilling to trust the information exchanged.

Non-repudiation refers to the inability to prove that a specific individual or organization initiated a digital certificate or transaction.

Without non-repudiation, a party can deny responsibility for a transaction, and there is no way to prove that the transaction occurred.

Organizations must deploy robust encryption algorithms. Using digital signatures, timestamping, and secure logging can provide evidence of the authenticity of digital certificates and transactions.

Regular security audits and incident response plans can identify and mitigate potential trust and non-repudiation issues.
