SSH for secure email transmission
SSH for secure email transmission
SSH is typically used for secure remote access and control, not email transmission.
TLS function in network security
TLS function in network security
TLS provides data encryption at the transport layer, ensuring secure communication between two parties.
Man-in-the-Middle (MitM) attack
Man-in-the-Middle (MitM) attack
A Man-in-the-Middle (MitM) attack involves an attacker intercepting communication between two parties, creating a fake website to obtain sensitive information.

Study Notes
Email Security
- Not all email protocols are secure, and some are not typically used for secure email transmission.
Transport Layer Security
- TLS (Transport Layer Security) provides data encryption at the transport layer.
Computer Attacks
- Phishing involves replacing a legitimate website with a fake one, a type of computer attack.
SSH Digital Signature
- The RSA algorithm is used to create a digital signature in the SSH protocol.
Asymmetric Encryption
- RSA is an asymmetric encryption algorithm, which means it uses a pair of keys for encryption and decryption.
Cryptographic Protocols
- PGP (Pretty Good Privacy) provides message confidentiality through public key encryption.
Cryptography Models
- A random oracle model is a theoretical model used in cryptography to analyze the security of cryptographic protocols.
Asymmetric Cryptography
- Asymmetric cryptography uses a pair of keys: a private key and a public key.
SSH Protocol
- The SSH protocol is used for secure remote access to a computer or network.
Network Security
- IPSec (Internet Protocol Security) provides confidentiality, integrity, and authenticity of data at the network layer.
