Correct answer: a
Digital signature is a method to realize non-repudiation in business activities. Digital signature is a mathematical method to confirm that an electronic document is signed or verified by a specific person or entity. Digital signature uses public key infrastructure (PKI) technology, in which the signer uses his private key to sign the document and the receiver uses the signer's public key to verify the authenticity of the signature.
Digital signature provides a reliable method to ensure the authenticity, integrity and non-repudiation of documents or transactions. Once a document or transaction is signed and verified, the signer cannot deny its content or participation. This makes digital signature a safe and reliable authentication method for commercial transactions, contracts and other important documents.
Therefore, digital signature technology has been widely used in e-commerce, banks and financial institutions, government departments and other occasions that need to ensure the authenticity of transactions and documents.
