<\/div>\n<\/figure>\nOnly people with access to the private key (also called a decryption key) can decrypt and read encoded data. Encrypted data or ciphertext is unreadable to people without access to the private key. Unencrypted data is called plaintext and encrypted data is called ciphertext. This also protects your sensitive data from theft, modification, or disclosure. Encrypting or encoding is a technique that converts data from one form to another using a key. The best example of encoding is the process of squashing graphics into bytes.<\/p>\n
Functions of data encryption<\/h2>\n
Data is passed through a cipher to encrypt it. This cipher is an algorithm that encodes your data according to a key. Only people with access to the key can decrypt your encrypted data.<\/p>\n The cipher is the engine of the encryption and the key is what shows the cipher how to encode your data. When hackers can\u2019t find your key, your data is impenetrable in every possible scenario.There are three different sizes of keys; 128, 192, and 256-bit keys. The longest key is the hardest to crack. Even when you use the smallest key and the best computer, it would still take 25 years to brute force that key.<\/p>\n Encryption is a very broad term, it works differently depending on what you\u2019re encrypting. An example of data encryption technology is encrypted online connections. When you check out clothing from a retailer, your browser uses SSL (Secure Sockets Layer) or TLS (Transport Layer Security) to encrypt your online connection. When you checkout, your computer sends a packet of data to the server it wants to connect with.Your computer is asking the server to verify its identity with this packet of data. Next, the server sends back a digital certificate. This certificate is a piece of code that contains a public key and an encrypted signature. Now that the computer has the public key, you can send encrypted messages to the server. You can\u2019t decrypt these messages with the public key, to decrypt them you need the private key. Only the server has the private key. What we described now, is an example of asymmetric encryption.<\/p>\n There are 2 different kinds of data encryption: symmetric encryption vs asymmetric encryption.<\/p>\n Symmetric encryption uses symmetric key algorithms. This means that the same private key encrypts and decrypts all the data. Symmetric encryption is efficient, fast, and easy for large amounts of data because it only needs one key. But it\u2019s harder to keep the private key a secret with symmetric encryption. The sender of the data has to exchange the encryption key with the recipient before he can decrypt it. Because companies need to distribute and manage huge quantities of keys, this process can go wrong very easily. That\u2019s why a lot of companies have adapted to asymmetric encryption.<\/p>\n Asymmetric encryption uses asymmetric key algorithms to encrypt data. Asymmetric encryption uses two linked keys, a public key and a private key. With the public key, you can encrypt the data and with the private key, you can decrypt the data. Asymmetric encryption is the most secure version of encryption. Only those with a private key can decrypt the encoded data. Users never need to reveal their private keys, so it’s harder for cybercriminals to discover a user\u2019s key during transmission.<\/p>\n Employees are a risk for companies. They want to protect their data and prevent data loss. But employees use web applications, removable media, and external devices on a daily basis. This is a risk for the sensitive data of the company.A critical component of data loss prevention is e-mail control and encryption. Good data loss prevention software allows your employees to continue working, while sensitive data in e-mails are encrypted.Data encryption may seem complicated. But with a good data loss prevention solution, you can rest assured that your data is safe.<\/p>\n Data encryption technology protects your sensitive data against a lot of cryptographic attacks.<\/p>\n A hacker could use a brute-force attack. This is an attack where hackers can decrypt data if they are given the required time to do so. They try to guess passwords by making a bunch of combinations as fast as possible. This can take a very long time. A brute-force attack is the only attack that can be used against data encryption. But because this attack takes a very long time, it\u2019s practically useless.<\/p>\n Another possibility is a cryptographic attack. This is a method that circumvents the security of a cryptographic system by finding a weakness. This can be a weakness in the code, the cipher or the key management scheme, or the cryptographic protocol. It’s also called \u201ccryptoanalysis\u201d.<\/p>\n Man-in-the-Middle (MitM) attack is another type of attack. During this attack, a hacker inserts themselves in between a communication channel between two people. The hacker tries to intercept the messages the people send to each other and tries to decrypt them.<\/p>\n We also have the replay attack. During this attack, the hacker copies an earlier interaction. For example, someone buying a bike. By replaying the same actions as the buyer, the hacker can cause some serious damage concerning the person\u2019s bank account.<\/p>\n The Side-channel attack is another sort of cryptographic attack. This is an attack that uses the side effects of cryptographic operations to get information in order to get to the data. This attack uses the time it takes to perform these operations to determine the secret key and the electrical power of a computer while performing encryption or decryption.<\/p>\n Power analysis attacks use the amount of power used and how long the power of a computer is used. This reveals information about the data that is processed by the cryptographic algorithm on your computer.<\/p>\n Timing attacks exploit the cryptographic algorithm which may take different amounts of time to run plaintexts or secret keys.<\/p>\n All Jimber solutions use data encryption technology. Browser Isolation uses it to secure browsers. Web application isolation uses it to secure corporate applications. The Digital Vault is an excellent example of data encryption in web application isolation.<\/p>\n The Digital Vault uses an application so you can share and save documents in a safe way. Our application uses data encryption technology to encrypt all data so that documents are only visible to users and unreadable to others. Log in easily and securely to the digital vault with our application. Only the owner of the phone can access and edit the documents. Using a private key, only you can manage your files.<\/p>\n Notre application Coffre-fort num\u00e9rique utilise une cl\u00e9 priv\u00e9e qui permet le cryptage. Le cryptage des donn\u00e9es emp\u00eache la perte de donn\u00e9es, car m\u00eame si les donn\u00e9es sont vol\u00e9es, elles ne peuvent pas \u00eatre lues par des personnes non autoris\u00e9es. M\u00eame si un pirate informatique acc\u00e8de physiquement au serveur sur lequel les fichiers sont h\u00e9berg\u00e9s, il ne sera pas en mesure de les d\u00e9crypter. Vos informations sensibles sont donc toujours prot\u00e9g\u00e9es. <\/p>\n Le coffre-fort num\u00e9rique est un excellent exemple de cryptage asym\u00e9trique. Deux cl\u00e9s sont cr\u00e9\u00e9es pour chaque compte, une cl\u00e9 publique et une cl\u00e9 priv\u00e9e. Ces cl\u00e9s sont utilis\u00e9es pour crypter et d\u00e9crypter les donn\u00e9es du coffre-fort num\u00e9rique. Les cl\u00e9s publique et priv\u00e9e ne sont accessibles que lorsque vous \u00eates connect\u00e9 \u00e0 votre chambre forte. Les cl\u00e9s peuvent \u00eatre utilis\u00e9es pour envoyer des donn\u00e9es crypt\u00e9es et d\u00e9crypter les donn\u00e9es re\u00e7ues. Les cl\u00e9s peuvent \u00e9galement \u00eatre utilis\u00e9es pour les signatures num\u00e9riques, afin que l’autre personne puisse s’assurer qu’il s’agit bien de votre document. Gr\u00e2ce \u00e0 ce processus, il est plus difficile pour les pirates de d\u00e9couvrir la cl\u00e9 d’un utilisateur. <\/p>\n La chambre forte num\u00e9rique est une excellente protection contre les attaques cryptographiques. Le cryptage des donn\u00e9es peut r\u00e9duire le nombre de cyberattaques s’il est mis en \u0153uvre correctement et mis \u00e0 jour fr\u00e9quemment. Notre technologie de cryptage des donn\u00e9es peut en principe att\u00e9nuer toutes les attaques cryptographiques, \u00e0 l’exception des attaques par force brute. Bien que les attaques par force brute soient toujours possibles, elles sont pratiquement inutiles parce qu’elles prennent beaucoup de temps avant d’aboutir.Le coffre-fort num\u00e9rique offre une grande facilit\u00e9 d’utilisation et une grande \u00e9volutivit\u00e9, gr\u00e2ce au cryptage des donn\u00e9es. Le coffre-fort num\u00e9rique est pratique \u00e0 utiliser pour les employ\u00e9s et \u00e9volutif pour s’adapter \u00e0 la croissance d’une organisation et \u00e0 l’\u00e9volution de ses besoins en mati\u00e8re de cybers\u00e9curit\u00e9.D\u00e9couvrez notre coffre-fort num\u00e9rique ici pour partager des fichiers et des mots de passe en toute s\u00e9curit\u00e9<\/strong>:https:\/\/jimber.io\/digital-vault-secure-files-password\/Read pour en savoir plus sur les mythes du cryptage des donn\u00e9es<\/strong>:https:\/\/www.wired.com\/insights\/2013\/05\/9-biggest-data-encryption-myths-busted-2\/<\/a> <\/p>\n","protected":false},"excerpt":{"rendered":" Data encryption is there to protect sensitive and private data.
