Module 21: Public Key Cryptography Quiz Answers It is used to securely exchange encryption keys in the setup of IPsec VPNs 12 What technology allows users to verify the identity of a website and to trust code that is downloaded from the Internet? digital signature hash algorithm asymmetric key algorithm encryption
8. 8. 2 Module 8: Public Key Cryptography Quiz Answers Explanation: DH is an asymmetric mathematical algorithm that allows two computers to generate an identical shared secret, without having communicated before Asymmetric key systems are extremely slow for any sort of bulk encryption It is common to encrypt the bulk of the traffic using a symmetric algorithm such as DES, 3DES, or AES, and use the DH algorithm to create keys that will be used by
Which statement describes asymmetric encryption algorithms? They are also called shared-secret key algorithms They are relatively slow because they are based on difficult computational algorithms Explanation: DES, 3DES, and AES are examples of symmetric encryption algorithms (also known as shared secret key algorithms) The usual key length for symmetric algorithms is 80-256 bits
Modules 15 – 17: Cryptography Group Exam Answers Full Public key infrastructure (PKI) is an asymmetric encryption algorithm based on the assumption that the two communicating parties have not previously shared a secret key HMAC is a hash message authentication code that guarantees that the message is not a forgery and actually comes from the authentic source 8
