Learning Goals

• Define core cryptographic objectives, including confidentiality, integrity, authentication, and non-repudiation.
• Differentiate symmetric and asymmetric cryptography based on key usage, performance, and typical applications.
• Explain the purpose of hashing and digital signatures in verifying data integrity and sender authenticity.
• Identify how encryption supports secure communication for application-layer services and sensitive data exchange.
• Analyze basic threat scenarios and select appropriate cryptographic concepts to mitigate eavesdropping, tampering, and impersonation.
