Flashcards in Asymmetric Encryption Deck (10):
In asymmetric encryption, what keys are used?
A paired public and private key
Secure asymmetric encryption using a minimum of 1,024 bit keys. Frequently used for digital signatures in e-mail. Uses a paired public and private key. Uses a static key.
What are static keys?
Semipermanent, can stay the same over a long period of time.
What are ephemeral keys?
Includes a private and public ephemeral key, re-created for each session.
What is Perfect forward secrecy?
PFS, indicates that random public keys are created for each session.
Where is Elliptic curve cryptography used?
Small wireless devices; does not take much processing power.
What is Diffie-Hellman?
Key exchange algorithm used to share a symmetric key between 2 parties. Supports static and ephemeral keys.
What is DHE?
Diffie-Hellman Ephemeral, uses ephemeral keys, and generates new keys for each session.
What is ECDHE?
Elliptic Curve DHE, uses ephemeral keys generated using ECC.
