0 likes21 views
The document discusses security attacks and defines six key security properties: confidentiality, integrity, availability, authenticity, non-repudiation, and authorization. It also mentions secret-key cryptography, public-key cryptography, and two encryption modes - Electronic Code Book mode and Output Feedback mode. Process behavior topics like deadlocks, livelocks, nondeterminism, and recursion are covered. Authentication is defined as verification of an entity's claimed identity and can include additional information like nonces and keys.
