1 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." -
2 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." -
3 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." -
4 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." -
5 Digital Signature Standard
A standard that uses the Digital Signature Algorithm (DSA) for its signature algorithm and Secure Hash Algorithm (SHA-1) as its message hash algorithm. DSA is a public-key cipher that is used only to generate digital signatures and cannot be used for data encryption.English-Arabic terms dictionary > Digital Signature Standard

6 DSS
A standard that uses the Digital Signature Algorithm (DSA) for its signature algorithm and Secure Hash Algorithm (SHA-1) as its message hash algorithm. DSA is a public-key cipher that is used only to generate digital signatures and cannot be used for data encryption.
