Vernam cipher Study guides, Revision notes & Summaries

Asymmetric encryption - 1. Is the most common method used to conceal small blocks of data, such as encryption keys and hash function values, which are used in digital signatures encryption - 2. A common technique for masking contents of messages or other information traffic so that opponents cannot extract the information from the message is. Replay - 3. Involves the passive capture of a data unit and its subsequent retransmission to produce an unauthorized effect. Layering - 4. Refers ...
