The primary function of information encryption<br />- The purpose of information encryption is to protect the confidentiality of digital information, which is stored on computer systems, and transmitted using the Internet or other computer networks, the old data encryption standard (DES) has been replaced by modern encryption algorithms, which play a crucial role in the security of IT systems and Telecommunications .<br />These algorithms provide confidentiality and crucial direct security initiatives, including authentication, integrity, and non-repudiation. Authentication allows verification of the message's origin, and integrity provides evidence that the contents of the message have not changed since it was sent. Also, no rejection ensures that the sender cannot Refuse to send a message.<br /><br />Information encryption process<br />- Data or plain text is encrypted using an encryption algorithm and an encryption key, resulting in encrypted text, which can be displayed only in its original form, if decrypted using the correct key.<br />- Symmetric encryption keys use the same secret key to encrypt and decrypt a message or file, although symmetric key encryption is much faster than asymmetric encryption, the sender must exchange the encryption key with the recipient before it can decrypt it, and since companies find Most of the information encryption services were adapted, and an asymmetric algorithm was used to exchange the secret key, after using a similar algorithm to encrypt the data.<br />- On the other hand, asymmetric encryption, sometimes referred to as public-key encryption, uses two different keys, one public and the other private. The public key can be shared as it is called with everyone, but the private key, the algorithm Rivest-Shamir-Adleman ( RSA) is an encryption system for public-key encryption, widely used to secure sensitive data, especially when it is sent over an insecure network such as the Internet. The popularity of the RSA algorithm comes from the fact that both public and private keys can encrypt a message to ensure confidentiality and integrity. Authenticity, and the inability of electronic communications and data NAT through the use of digital signatures.<br /><br />Challenges of contemporary encryption<br />- The primary method of attacking encryption today is brute force or experimenting with random keys until a true one is found. Of course, the key length determines the possible number of keys, and affects the reasonableness of this type of attack, it is essential to keep in mind that the encryption strength is directly proportional with the size of the key, but the larger the volume of the key the more resources needed to perform the account.<br />- Alternative methods for breaking crypto-channel attacks include cryptanalysis. Crypto-channel attacks go after the implementation of the codes, rather than the actual codes themselves. These attacks tend to succeed in the event of system design or implementation error. Similarly, cryptanalysis means finding a point. Weakness in the code and its exploitation, blinding often occurs when the code itself is malfunctioning.<br /><br />- As mentioned above, email control and encryption are other critical components of the information loss prevention solution. Secure encrypted email is the only solution for organizational compliance, remote workforce and BYOD, and outsourcing of the project. By continuing to work and collaborate through email while programs and tools are tagging, categorizing, and encrypting sensitive data in email messages and attachments proactively, the best solutions to prevent data loss automatically, warn sensitive information Block and encrypt, based on message content and context, such as user, category information, and recipient.<br />- Although information encryption may seem daunting and complex, the loss prevention program handles it reliably every day. Encryption of information should not be something your organization is trying to resolve on its own; choose one of the top data loss prevention programs, and Which provides encryption of data using device and email, control applications, and make sure your data is secure.<br />
