Nowadays we know data is the most important aspect of our life, being it personal, economic or commercial. As we increasingly use online, data is always at risk. In spite of all the best efforts made, there are possibilities that your computer is infected with malware, ransomware or any cyber criminals that your antivirus cannot detect. Malware sends sensitive data on your computer and sends it to the cybercriminal running the malware. It is supreme to keep data secure. This is where technology comes into place. Technology makes it difficult task for hackers to data breaches. We have to rely on encryption software keeping cyber criminals from reaching our data. Encryption helps in keeping our data private and protected. It acts as a lock from cybercrime, providing an extra layer of protection in safeguarding our critical credentials. Encryption secures our data from hackers reading our information.
Encryption is the process of converting plain readable form text to an unreadable form text so as to protect data or a conversation between two parties or from an unauthorized person. Data encryption ensures the confidentiality of data by converting it into coded information known as ciphertext, which further, can only be decrypted with a unique decryption key generated either during or before encryption. Data encryption can be used during data storage or transmission, and is usually used in conjunction with authentication services to support keys.
Various types of encryptions are Manual Encryption, Transparent Encryption, Symmetric Encryption and Asymmetric Encryption.
What is Manual Encryption?
Manual encryption are computer programs that digitally encrypt multiple pieces of data. Manual encryption involves extensive user involvement. The files which have to be encrypted are selected and the encryption type is to be selected from the list supported by the security system
What is Transparent Encryption?
Transparent encryption provides permanent file-level encryption, protecting against unauthorized access by users and processes in physical, virtual and cloud environments. The application is seamless and transparent to applications/databases and storage. It can run across an enterprise environment and keep both business and operational processes unchanged. It is one of the most secure encryption types available because it misses nothing when using manual encryption. Every executable application and file created on the computer has an encrypted copy that can withstand power surges and protects data even if the computer is stolen.
What is Symmetric Encryption?
Symmetric encryption is a simple, easy-to-use method of encryption. This encryption is also called secret key encryption. It uses only one key called shared key, for both encryption and decryption of electronic data. With symmetric encryption, communicating units must exchange a key to use it in the decryption process. In symmetric encryption, data is “encrypted” so that it cannot be understood by anyone who does not have the secret key to decrypt it.
The secret key is generated by a secure random number generator (RNG). The main issue that can be found while using symmetric encryption is that the key is shared between the sender and the recipient of the data. So it is important to be cautious about maintaining a secure method of key exchange, else there are possibilities a third party intercepts the key during the exchange and an unauthorized person can easily decrypt the data.
What is Asymmetric Encryption?
Asymmetric encryption, also called public key encryption, relies on a key pair. In this method, two mathematically related keys are created; one called the public key and the other called the private key. The private key is never shared; it is kept secret and used only by the owner. Public key is shared with anyone who wants it.
The advantage of asymmetric encryption is that a secret key is not transmitted. Instead, the public key is published openly.
Examples of Symmetric and Asymmetric Encryption:
Symmetric: Blowfish, AES, RC4, DES, RC5, RC6, A5/1, A5/2, FISH, Helix, ISAAC etc
Asymmetric: EIGamal, RSA, DSA, Elliptic curve techniques, PKCS, PGP etc
In reference to encryption, it is always best to use the most recent systems. It is recommended to always use the most appropriate encryption algorithm in accordance with the task you handle. As cryptography takes a new turn, new algorithms are also developed to reach intruders and protect data, in turn improving confidentiality. Hackers are sure to make it difficult for the experts in the coming years too.
