In-Depth Information
Encryption and signature schemes are the most basic applications of
cryptography. Their main utility is in providing secret and reliable
communication over insecure communication media. Loosely speaking,
encryption schemes are used to ensure the secrecy (or privacy) of the
actual information being communicated, whereas signature schemes are
used to ensure its reliability (or authenticity). In this part we survey
these basic applications as well as the construction of general secure
cryptographic protocols. For more details regarding the contents of the
current part, see our recent textbook (67).
