Read MoreWhy do we use Group, Ring and Fields in Information Security?
Groups, rings, and fields are the important elements of a branch of mathematics called as abstract algebra, or modern algebra. In abstract algebra, it is concerned with sets on whose elements and it can operate algebraically; that is, it can combine two elements of the set, perhaps in multiple ways, and it can obtain a third element of the set.GroupA group (G) is indicated by {G, ∙}. It is a group of elements with a binary operation ′ ∙ ′ that satisfies four properties. The properties of Group are as follows −Closure − If a and b are elements of ...

Read MoreWhat is the most security-critical component of DES round function?
There are various component of DES which are as follows −Key Transformation − An initial 64-bit key is changed into a 56-bit key by discarding each 8th bit of the initial key. Therefore for each round, a 56 bit key is applicable. From this 56-bit key, there are several 48-bit subkey is produced during every round utilizing a procedure is known as key transformation. The 56-bit key is breaked into two halves, each 28 bits.Round12345678910111213141516Number of key bits shifted1122222212222221No of key bits shifted per roundIn key transformation procedure, it includes permutation and selection of a 48-bit key from original 56-bit ...

Read MoreWhat is the difference between Encryption and Steganography in Information Security?
EncryptionData encryption is a method of translating information from plaintext (unencrypted) to ciphertext (encrypted). Users can access encrypted information with an encryption key and decrypted information with a decryption key.There are large amounts of sensitive information handled and stored online in the cloud or on combined servers. Encryption needs cybersecurity to protect against brute-force and cyber-attacks, such as malware and ransomware.Data encryption operates by protecting transmitted digital information on the cloud and computer systems. There are two types of digital information, transmitted information or in-flight information and stored digital information or data at rest.The main objective of data encryption is ...
Read MoreWhat are the techniques of Monoalphabetic Cipher?
There are various techniques of Monoalphabetic cipher which are as follows −Additive Cipher − Additive cipher is one method of changing a permutation of the letters of the alphabet. Each letter in the alphabet is cyclically changed by the equivalent amount and the relative order of the letters is kept the similar.The number of position the letter has been transformed is known as key. For example if it can use a key value of 5, ‘a’ is changed 5 positions right in the alphabet to ‘F’, ‘b’, to ‘G’ and so on.The letter ‘u’ is changed to ‘Z’ and thus ...
Read MoreHow to alter your IP and location with VPN?
Whatever your motivation for utilizing a VPN, it always changes your IP address in the eyes of the outside world.

What makes you think you'd want to do that? And what happens if it doesn't work? Continue reading for a step-by-step guide ...
Read MoreHow many Encryption Rounds are there in IDEA?
IDEA stands for the International Data Encryption Algorithm. IDEA is a symmetric-key block cipher. It is denoted the same key can be used to encrypt the plaintext and decrypt the ciphertext.IDEA needed both the encrypting and decrypting parties to have a secret key that is different from a public-key and other asymmetric encryption schemes. The secret key popular to the encrypting party.IDEA is a patented and universally accessible block encryption algorithm, which allows the effective protection of transmitted and stored information against unauthorized access by third parties.The fundamental element for the development of IDEA were military durability for all security ...
