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 Secure Hash Algorithm 1
"An algorithm that generates a 160-bit hash value from an arbitrary amount of input data. SHA-1 is used with the Digital Signature Algorithm (DSA) in the Digital Signature Standard (DSS), among other places." -
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 Black-Scholes
A technical algorithm used to determine the present value of a future stock price (for determining the value of newly awarded stock options). -
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. -
7 SHA-1
"An algorithm that generates a 160-bit hash value from an arbitrary amount of input data. SHA-1 is used with the Digital Signature Algorithm (DSA) in the Digital Signature Standard (DSS), among other places." -
8 O notation
"An indication of the relative performance of an algorithm. An algorithm or the method that implements it is said to be O(1) if its execution is a constant, O(log n) if its execution is proportional to the natural log of n, or O(n) if its execution is proportional to n. O notation is frequently used as a way to compare the relative performance of operations on collections, in which case n is usually the number of elements in the collection." -
9 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." -
10 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." -
11 symmetric encryption
"An encryption algorithm that requires the same secret key to be used for both encryption and decryption. Because of its speed, symmetric encryption is typically used when a message sender needs to encrypt large amounts of data." -
12 secret key encryption
"An encryption algorithm that requires the same secret key to be used for both encryption and decryption. Because of its speed, symmetric encryption is typically used when a message sender needs to encrypt large amounts of data." -
13 hash
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
14 message digest
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
15 key
"In encryption, authentication, and digital signatures, a value used in combination with an algorithm to encrypt or decrypt information." -
16 key
"In IP security (IPSec), a value used in combination with an algorithm to encrypt or decrypt data. Key settings for IPSec are configurable to provide greater security." -
17 encryption key
A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data. -
18 hash code
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
19 Data Encryption Standard
"An encryption algorithm that uses a 56-bit key and maps a 64-bit input block to a 64-bit output block. The key appears to be a 64-bit key, but one bit in each of the eight bytes is used for odd parity, resulting in 56 bits of usable key." -
20 DES
"An encryption algorithm that uses a 56-bit key and maps a 64-bit input block to a 64-bit output block. The key appears to be a 64-bit key, but one bit in each of the eight bytes is used for odd parity, resulting in 56 bits of usable key."
