Explain the requirements of Public key cryptography?
in public key cryptography there should be two key called private key and public key private key kept in secret and public key put in public in public key cryptography ... -
State Fermat’s Theorem. Find out the result of 3^12 mod 11 using second version of ...
Fermat's states that if p is a prime number and a is an integer not divisible by p then a^(p-1)=1(mod p) or the modification of fermat's theorem is that a^p=a ... -
What is ransomware?
Ransomware is a type of malware which restrict the access to the infected system in some way and demand a ransom to lift the restriction. Ransomware usually installed when clicking ... -
Explain about Message Authentication Code algorithm.?
In cryptography, a message authentication code, sometimes known as a tag, is a short piece of information used to authenticate a message—in other words, to confirm that the message came ... -
Explain RSA algorithm with example ?
RSA (Rivest–Shamir–Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys. This is also called public key ... -
Explain Diffie Hellman key exchange algorithm ?
Diffie–Hellman key exchange is a method of securely exchanging cryptographic keys over a public channel Purpose is to enable two users to securely exchange a key that can then be ... -
What is Cipher Feed Back mode (CFB)?
Ciphertext feedback (CFB) is a mode of operation for a block cipher. In contrast to the cipher block chaining (CBC) mode, which encrypts a set number of bits of plaintext at a time, it is at times ... -
Explain the concept of public key cryptography?
Public-key cryptography, or asymmetric cryptography, is a cryptographic system that uses pairs of keys: public keys, (which may be public to widely) , and private keys, (which will be known ... -
Describe the various components used for message integrity in cryptography ?
The types of functions that may be used to produce an authenticator may be grouped into three classes Hash function A function that maps a message of any length into ... -
Explain various digital signature schemes with suitable diagram?
A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very strong ...
