WebOct 15, 2014 · Page 4. Public Key Cryptography. Public key cryptography is an asymmetric scheme that uses a pair of keys for encryption: a public key, which encrypts data, and a corresponding private, or secret key for decryption. Page 5. PGP• PGP combines some of the best features of both. conventional and public key cryptography. PGP is a hybrid … Webassumptions. 4. Lattice-Based Cryptography. Seemingly very different assumptions from. factoring, discrete log, elliptic curves. Simple descriptions and implementations. Very parallelizable. Resists quantum attacks (we think) Security based on worst-case problems.
