Answer:
Symmetric encryption is faster than asymmetric encryption, but it cannot be used to provide non-repudiation of contracts.
Explanation:
Symmetric encryption is a type of encryption where only one key (a secret key) is used to both encrypt and decrypt electronic information. Symmetric encryption uses a single key that needs to be shared among the people who need to receive the message while asymmetrical encryption uses a pair of public key and a private key to encrypt and decrypt messages when communicating. Symmetric encryption cannot be used for non-repudiation because the key is shared by both parties, making it difficult to prove who created and encrypted the document.
