Data Encryption

A DEFINITION OF DATA ENCRYPTION:

Data encryptioninterpretsknowledgeinto anothertype, or code,in order thatsolelyfolkswith access to a secret key (formallyknown asacryptographykey) orarcanumwillscanit.

Encryptedknowledgeis usuallymentionedas ciphertext,whereasunencryptedknowledgeis namedplaintext.Currently,encodingisone in allthe foremostwidespreadand effectiveknowledgesecuritystrategiesutilized byorganizations.

Two mainsorts ofencryption exist -unevenencryption, also known as public-key encryption, and symmetric encryption.

THE PRIMARY FUNCTION OF DATA ENCRYPTION:

These algorithmsofferconfidentiality and drive key security initiativesas well asauthentication, integrity, and non-repudiation.Authenticationpermitsfor the verification of a message’s origin, and integrity provides proof that a message’s contents have not changed since it was sent.

Additionally, non-repudiation ensures that a message sender cannot deny sending the message.

THE PROCESS OF DATA ENCRYPTION

Data, or plaintext, is encrypted with an encryption algorithm and an encryption key.

The processends up inciphertext, which only can be viewed in its original form if it is decrypted with the correct key.

Symmetric-key ciphers useconstantsecret key for encrypting and decrypting a message or file.
While symmetric-keyencodingis wayquickerthanunevenencoding, the sendershouldexchange theencodingkey with the recipient before hewilldecipherit.

Asfirmsrealizethemselveseager tofirmlydistribute and manageBrobdingnagianquantities of keys, most data encryption services have adapted and use an asymmetric algorithm to exchange the secret

Onthe oppositehand,unevencryptography,typicallymentionedas public-key cryptography, uses2completely differentkeys, one public and one private.

The public key,because itis called, may be shared with everyone, but the private key must be protected.

The Rivest-Sharmir-Adleman (RSA) algorithm is a cryptosystem for public-key encryption that is widely used to secure sensitive data, especially when it is sent over an insecure network like the internet. The RSA algorithm’s popularity comes from the fact that both the public and private keys can encrypt a message to assure the confidentiality, integrity, authenticity, and non-repudiability of electronic communications and data through the use of digital signatures.

CHALLENGES TO CONTEMPORARY ENCRYPTION

The most basicmethodologyof attack onencodingthese daysis brute force, or trying random keys until the right one is found.

Of course, the length of the key determines thepotentialrangeof keys and affects thebelievabilityofthis kindof attack.

It isvitalto stayin mind thatencodingstrength is directly proportional to key size, but as the key size increases so do the number of resources required

to perform the computation.
Alternative methods of breaking a cipher include side-channel attacks and cryptanalysis.
Side-channel attacksfollowthe implementation of the cipher,instead ofthe particularcipher itself.
These attacks tend to succeed ifthere'sa mistakein systemstyleor execution.
Likewise,cryptanalyticsmeans thatfinding a weaknesswithin thecipher and exploiting it.
