Short example sentences

In a secure asymmetric key encryption scheme, the private key should not be deducible from the public key. (18 words)

In the alternative, when a message is encrypted with the public key, only the private key can decrypt it. (19 words)

In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. (20 words)

Longer example sentences

Most are used in hybrid cryptosystems for reasons of efficiency – in such a cryptosystem, a shared secret key (" session key ") is generated by one party, and this much briefer session key is then encrypted by each recipient's public key. (40 words)

Note that the public key scheme is not used for encryption in this form; i.e. the goal is not to achieve confidentiality, since a message signed with a private key can be read by anyone using the public key. (40 words)

A given public key (or more specifically, information binding a user name to a key) may be digitally signed by a third party user to attest to the association between someone (actually a user name) and the key. (38 words)

Example sentences (20)

Description Two of the best-known uses of public-key cryptography are: * Public-key encryption, in which a message is encrypted with a recipient's public key.

Most are used in hybrid cryptosystems for reasons of efficiency – in such a cryptosystem, a shared secret key (" session key ") is generated by one party, and this much briefer session key is then encrypted by each recipient's public key.

The first key that is required is a public key and the second key that is required is a private key.

In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key.

Note that the public key scheme is not used for encryption in this form; i.e. the goal is not to achieve confidentiality, since a message signed with a private key can be read by anyone using the public key.

The strength of a public-key cryptography system relies on the degree of difficulty (computational impracticality) for a properly generated private key to be determined from its corresponding public key.

A given public key (or more specifically, information binding a user name to a key) may be digitally signed by a third party user to attest to the association between someone (actually a user name) and the key.

In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt.

Advertentie

In a secure asymmetric key encryption scheme, the private key should not be deducible from the public key.

The public key is placed on all computers that must allow access to the owner of the matching private key (the owner keeps the private key secret).

Both Public Key Encryption and digital signatures make up the foundation of Enveloped Public Key Encryption (these two processes are described in full in their own sections).

The public key consists of the modulus n and the public (or encryption) exponent e. The private key consists of the modulus n and the private (or decryption) exponent d, which must be kept secret.

This is commonly done using a public key infrastructure (PKI) and the public key↔user association is attested by the operator of the PKI (called a certificate authority ).

Users have a public key and a private key – senders use the former to encrypt messages, which can only be decoded by someone who has access to the latter.

All public key/private key cryptosystems have the same problem, even if in slightly different guises, and no fully satisfactory solution is known.

A Recovery Agent is a user who is authorized by a public key recovery certificate to decrypt files belonging to other users using a special private key.

First, the authenticity of a signature generated from a fixed message and fixed private key can be verified by using the corresponding public key.

Furthermore, unlike RSA, it is one-way: the public key is used only for encryption, and the private key is used only for decryption.

In the alternative, when a message is encrypted with the public key, only the private key can decrypt it.

On the one hand, a message revoking a public key certificate should be spread as fast as possible, while on the other hand, parts of the system might be rendered inoperable before a new key can be installed.
