1 public key
"The nonsecret half of a cryptographic key pair that is used with a public key algorithm. Public keys are typically used when encrypting a session key, verifying a digital signature, or encrypting data that can be decrypted with the corresponding private key." -
2 public key algorithm
"An asymmetric cipher that uses two keys, one for encryption, the public key, and the other for decryption, the private key. As implied by the key names, the public key used to encode plaintext can be made available to anyone. However, the private key must remain secret. Only the private key can decrypt the ciphertext. The public key algorithm used in this process is slow (on the order of 1,000 times slower than symmetric algorithms), and is typically used to encrypt session keys or digitally sign a message." -
3 public key encryption
"A method of encryption that uses a pair of mathematically related keys: a public key and a corresponding private key. Either key can be used to encrypt data, but the corresponding key must be used to decrypt it." -
4 Public Key Cryptography Standards
"A family of standards for public key cryptography that includes RSA encryption, Diffie-Hellman key agreement, password-based encryption, extended-syntax, cryptographic message syntax, private key information syntax, and certificate request syntax, as well as selected attributes. Developed, owned, and maintained by RSA Data Security, Inc."English-Arabic terms dictionary > Public Key Cryptography Standards

5 key pair
A private key and its related public key. -
6 private key
"The secret half of a cryptographic key pair that is used with a public key algorithm. Private keys are typically used to decrypt a symmetric session key, digitally sign data, or decrypt data that has been encrypted with the corresponding public key." -
7 asymmetric key algorithm
"A method of encryption that uses a pair of mathematically related keys: a public key and a corresponding private key. Either key can be used to encrypt data, but the corresponding key must be used to decrypt it." -
8 endorsement key
"A key pair, consisting of a public key and a private key, which is used to verify that a TPM is genuine." -
9 Authority Key Identifier
"A certificate extension used by the certificate chaining engine to determine what certificate was used to sign a presented certificate. The AKI can contain the issuer name, serial number, public key information, or no information at all. By matching the information in a certificate’s AKI extension to a CA certificate’s Subject Key Identifier (SKI) extension, a certificate chain can be built."معرّف مفتاح المرجع -
10 storage root key
"On a system that incorporates a TPM, a cryptographic asymmetric key which is created at the root of the TPM key hierarchy (2048-bit RSA key) and which is used by the TPM to store protected data. The private portion of this key never leaves the TPM. The public part of this key is returned to the owner and needs to be carefully guarded since it uniquely identifies the TPM on the network, therefore is privacy sensitive." -
11 asymmetric encryption
"A method of encryption that uses a pair of mathematically related keys: a public key and a corresponding private key. Either key can be used to encrypt data, but the corresponding key must be used to decrypt it." -
12 AE
"A method of encryption that uses a pair of mathematically related keys: a public key and a corresponding private key. Either key can be used to encrypt data, but the corresponding key must be used to decrypt it."AE -
13 trust anchor
The public key of the public/private key pair that is used to sign a DNS zone. -
14 certificate
"A digital document that is commonly used for authentication and to help secure information on a network. A certificate binds a public key to an entity that holds the corresponding private key. Certificates are digitally signed by the certification authority that issues them, and they can be issued for a user, a computer, or a service." -
15 digital certificate
"A digital document that is commonly used for authentication and to help secure information on a network. A certificate binds a public key to an entity that holds the corresponding private key. Certificates are digitally signed by the certification authority that issues them, and they can be issued for a user, a computer, or a service." -
16 digital envelope
"Private messages encrypted using the recipient's public key. Enveloped messages can only be decrypted by using the recipient's private key, allowing only the recipient to understand the message." -

"An approach to public key cryptography based on properties of elliptic curves. The primary advantage of ECC is efficiency, which becomes important as devices get smaller and security requirements get more demanding. For example, ECC keys between 163 bits and 512 bits are one-sixth to one-thirtieth the size of equivalent security-level RSA keys. As key size increases the relative efficiency of ECC increases." -
