Exam 312-50v11 topic 1 question 91 discussion

Easy way to remember between Asymmetric and Symmetric: All alternatives of Symmetric start with the same letter S: Symmetric, Secret Key, Single Key, Shared Key, or Same key (used for encrypt & decrypt). Also, symmetric cryptography are Speedy when compared to asymmetric.

Diffie-Hellman (DH) is that part of the IKE protocol used for exchanging the material from which the symmetrical keys are built. The Diffie-Hellman algorithm builds an encryption key known as a "shared secret" from the private key of one party and the public key of the other. https://sc1.checkpoint.com/documents/R81/WebAdminGuides/EN/CP_R81_SitetoSiteVPN_AdminGuide/Topics-VPNSG/IPsec-and-IKE.htm

SSL uses both asymmetric and symmetric authentication mechanisms. Public-key encryption verifies the identities of the server, the client, or both. Page 3066.

PGP combines the best features of both conventional (around 1,000 times faster than public-key encryption) and public-key cryptography (solution to key distribution and data transmission issues), and is therefore known as a hybrid cryptosystem. (Page 3074)

Types of Cryptography Asymmetric Encryption Asymmetric encryption (public-key) uses different encryption keys, which are called public and private keys for encryption and decryption, respectively. (P.3018/3002)

I thought the question is a bit misleading as the type is asymmetric. But after a web search I see that it is also called public-key.
