What are the characteristics that are needed in secure hash function explain?
1) There should be a fixed length output generated by the hash function. 2) there should be easiness for finding the hash function for a certain or given message. 3)There should not be same hash value for the two different messages. This is because it goes against the property of hash function.
Which of the following is a legitimate responsibility of an organization regarding user private data?
Which of the following is a legitimate responsibility of an organization regarding user private data? Use proprietary methods for data collection to maintain security.
Which of the following is an advantage of hardware encryption over software encryption?
What is the most important advantage of hardware encryption over software encryption? Software encryption cannot be used on older computers. Hardware encryption is up to 10 times faster than software encryption. Software that performs encryption can be subject to attacks.
What is secure hash function in network security?
Hash Function is a function which has a huge role in making a System Secure as it converts normal data given to it as an irregular value of fixed length. … Hash Values are simply number but are often written in Hexadecimal. Computers manage values as Binary. Hash value is also a data and are often managed in Binary.

What is encryption algorithm in cryptography?
An encryption algorithm is the method used to transform data into ciphertext. An algorithm will use the encryption key in order to alter the data in a predictable way, so that even though the encrypted data will appear random, it can be turned back into plaintext by using the decryption key.
What are the cryptography algorithm?
Cryptographic algorithms are used for important tasks such as data encryption, authentication, and digital signatures, but one problem has to be solved to enable these algorithms: binding cryptographic keys to machine or user identities.
What is DES algorithm in cryptography?
Data Encryption Standard (DES) is a block cipher algorithm that takes plain text in blocks of 64 bits and converts them to ciphertext using keys of 48 bits. It is a symmetric key algorithm, which means that the same key is used for encrypting and decrypting data.
