| | Public-key cryptography - Wikipedia, the free encyclopedia |
 | | The introduction of elliptic curve cryptography by Neal Koblitz in the mid '80s has yielded a new family of analogous public key algorithms. | | | The security of asymmetric key algorithms is based on estimates of how difficult the underlying mathematical problem is to solve. | | | That is, it is not known to be impossible that some relation between the keys in a key pair, or a weakness in an algorithm's operation, might be found which would allow decryption without either key, or using only the encryption key. |

| | Public Key Cryptography |
| | A key is simply a parameter to the algorithm that allows the encryption and decryption process to occur. | | | Using this technology may require network management personnel with knowledge of public key cryptography and the use of software that implements public key cryptography and digital signature algorithms especially if an outside provider for public key infrastructures is NOT used. | | | Bruce Schneier, Applied Cryptography: Protocols, Algorithms, and Source Code in C, 2nd editon by, John Wiley and Sons, ISBN 0471128457, 1996. |

| | The Risks Of "Key Recovery," "Key Escrow," And "Trusted Third-Party" Encryption 1998 |
| | Other systems have "escrow agents" or "key recovery agents" that maintain the ability to recover the keys for a particular encrypted communication session or stored file; these systems require that such "session keys" be encrypted with a key known by a recovery agent and included with the data. | | | key recovery is used in a business environment, it would generally be one component of the overall data management policy of that business. | | | When a key does need to be recovered, it will frequently be a local matter, similar to the replacement of a misplaced office key or restoring a computer file with a backup copy. |

| | How PGP works |
| | In a public key environment, it is vital that you are assured that the public key to which you are encrypting data is in fact the public key of the intended recipient and not a forgery. | | | A key is a value that works with a cryptographic algorithm to produce a specific ciphertext. | | | The problems of key distribution are solved by public key cryptography, the concept of which was introduced by Whitfield Diffie and Martin Hellman in 1975. |

| | Netsurfer Focus on Cryptography and Privacy |
| | Cryptography in the computer age typically involves the translation of the original message into a new and incomprehensible one by a mathematical algorithm using a specific "key". | | | A challenge issued in 1977 to factor the key based on a 129 digit number (or 429 bits) was finally met in 1994 by an international group of over 600 volunteers and 1500 computers working for 8 months. | | | The RSA algorithm, used in public key cryptography and patented in the US, is based on the fact that it's easy to multiply two large prime numbers together, but hard to factor them out of the product. |

| | PKCS, Public-Key Cryptography Standards |
| | A modern branch of cryptography, popularly known as "public-key cryptography", in which the algorithms employ a pair of keys and use a different component of the pair for different steps of the algorithm. | | | Defines a syntax for data that may have cryptography applied to it, such as for digital signatures and digital envelopes. | | | First published in 1991 as a result of meetings with a small group of early adopters of public-key technology, the PKCS documents have become widely referenced and implemented. |

| | Cryptography FAQ (06/10: Public Key Cryptography) |
| | At the receiver side, the session key is decrypted using the public-key algorithms and the recovered `plaintext' key is used to decrypt the message. | | | The ``key exchange problem'' involves (1) ensuring that keys are exchanged so that the sender and receiver can perform encryption and decryption, and (2) doing so in such a way that ensures an eavesdropper or outside party cannot break the code. | | | In resolving the dilemma, public key cryptography has been considered by many to be a `revolutionary technology,' representing a breakthrough that makes routine communication encryption practical and potentially ubiquitous. |

| | CS 513 System Security -- Public Key Cryptography |
| | Some public key cryptography schemes also allow plaintext to be run through the decryption algorithm (using the private key). | | | In public key cryptography, some keys are known to everyone, so it would seem that the key distribution problem vanishes. | | | But first, lets try to establish an intuition for why we might want to consider an alternative to a secret key system using key distribution, and consequently what we're looking for in public key cryptography. |

| | RSA Security - 2.1.1 What is public-key cryptography? |
| | In order to solve the key management problem, Whitfield Diffie and Martin Hellman [DH76] introduced the concept of public-key cryptography in 1976. | | | To sign a message, Alice does a computation involving both her private key and the message itself. | | | To verify the signature, Bob does a computation involving the message, the purported signature, and Alice's public key. |

| | MPKC 2003: Mathematics of Public-Key Cryptography |
| | In this largely expository talk I will describe several techniques, which owe their origin to the application of number theory to cryptography, that have been successfully applied to classical problems arising in computational number theory. | | | Abstract: "We demonstrate that some finite fields, including GF(2^210), are weak for elliptic-curve cryptography in the sense that any instance of the elliptic-curve discrete-logarithm problem for any elliptic curve over these fields can be solved in significantly less time than it takes Pollard's rho method to solve the hardest instances. | | | MPKC 2003 will cover the latest developments in the mathematics of public-key cryptography. |

| | Why Use Private-Key Cryptography? |
| | Basically, because the known algorithms for doing public-key cryptography are very slow, relative to the private-key algorithms. | | | That's partly because you can get security with fewer bits using private-key algorithms, and partly because the public-key algorithms for encryption and decryption are linear in the number of bits of your key. | | | To be immune to linear-differential cryptanalysis, the number of rounds should probably scale with the logarithm of the number of bits you're using for a key. |

| | Prehistory of Public Key Cryptography |
| | At the ACM Computer and Communications Security conference in 1993, Whit Diffie organized a Festcolloquium in honor of Gus Simmons, who was retiring. | | | Gus said that he learned of public key crypto the same way many of us did, by reading Martin Gardner's column in Scientific American. | | | In other words, non-repudiation -- a classic use for public key cryptography -- was important; if a bomb is used, they (or their heirs, or civilization's heirs...) want to know who ordered it. |
