Stream CipherA stream cipher is one that encrypts a digital data flow one bit or one byte at a time. Stream Cipher generally encrypts one byte of the message at that moment rather than using blocks.For example, classical stream ciphers are the auto crucial Vigenère cipher and the Vernam cipher. ...

A cryptosystem is also called a cypher system. It implements cryptographic techniques using several cryptographic components including plain text, encryption algorithm, cypher text, decryption algorithm, and encryption key to support information security services.A cryptosystem is a set of algorithms such as one for the encryption of data and another for ...

A symmetric cipher is one that uses the similar key for encryption and decryption. The use of a symmetric cipher presents the well-known challenge of how to share the secret key between the parties fast, as an unauthorized party to the communication can prevent it and eavesdrop on future communication.There ...

AuthenticationAuthentication is the procedure of providing that an individual is the person that they claim to be. This contains matching a person’s claimed identity asserted through a credential (such as an ID card or unique ID number) against one or more authentication factors that are destined to that credential.Authentication is ...

Authorization is the procedure of permitting someone to do something. It defines it an approach to check if the user has permission to need a resource or not. It can represent that what data and information one user can access.It is also called as AuthZ. The authorization generally works with ... Read More

There are various types of cryptosystem which are as follows −Private Key cryptosystems − Symmetric encryption is also known as private-key encryption or secret-key encryption. It contains using the similar key for encryption and decryption. Encryption contains using an operation (an algorithm) to the data to be encrypted using the ... Read More

Authentication is the procedure which enables a sender and receiver of data to certify each other. If the sender and receiver of data cannot properly authenticate each other, there is no trust in the activities or data supported by either party.Authentication can include largely difficult and secure approach or can ...

Authentication is the procedure of checking if a user or entity or device is who claims to be. In another terms, it is a set of verification and Identification. Authentication falls into three elements which are as follows −The knowledge factors − Something the user understand such as a password, ... Read More

There are various techniques of Authentication which are as follows −Password-based authentication − It is the simplest approach of authentication. It needed the password for the specific username. If the password connect with the username and both details connect the system's database, the user should be strongly authenticated.Vault authentication − ... Read More

There are various method of Authentication which are as follows −Biometrics − Biometrics is a term that defines the measuring unique individual characteristics including the retina, the iris, fingerprints or even the face. Today, the concept is usually used by most people to define a method for protecting computers and ... Read More
