Books Cryptography and Network Security

Cryptography

• Cryptography
  • instead
  • Replacement
• Cryptanalysis
  • analysis
  • Exhaustive

Overview

The book focuses on two main areas:

• Cryptographic algorithms and protocols
  • Symmetric encryption
    • A content data block or the encrypted data stream of any size
  • Asymmetric encryption
    • Small encrypted data block for
  • Data integrity algorithms
    • Content protection for data blocks from being modified
  • Authentication Protocol
    • Used to authenticate the entity's authenticity
• Network and Internet security
  • Deter, prevent, detect and correct security violations occurring during transmission of information

For the definition of computer security

Three key objectives of the core of security (CIA triad):

• Confidentiality Confidentiality
  • Data confidentiality
  • Privacy
• Integrity Integrity
  • Data integrity
  • System Integrity
• Availability Availability

The other two are mentioned more concepts:

• Authenticity Authenticity
• Traceability Accountability

OSI Security Framework

• Security attacks
  • Passive Attack
    • Wiretapping and monitoring
    • Treatment focuses on prevention
  • Active attack
    • Camouflage, replay, message modification and denial of service
    • Focus detection processing
• Security Mechanism
  • Specific: encryption, digital signature, access control, data integrity, authentication exchange, traffic padding, routing control, notarization
  • General: credibility, security labels, event detection, security audit trails, security, recovery
• Security Services
  • Certification: peer entity authentication, data origin authentication
  • Access control
  • Data Confidentiality: connection confidentiality, connectionless confidentiality, privacy domain selection, flow confidentiality
  • Data integrity: the integrity of the connection with recovery function, connection integrity without recovery function, connection integrity selection field, connectionless integrity, connectionless integrity selection field
  • Non-repudiation: repudiation source, sink repudiation
