Which Types of Encryption Are Most Secure
- With an escalation in hackings over the past decade, breaches in our private data are ubiquitous meaning now, more than ever, encryption is key. Encryption is a security process that hides data until you are ready to use it by digitally jumbling the information. The software then unscrambles it once someone with the proper passwords tells it to. Our data is kept away from prying eyes thanks to cryptographic algorithms, which scramble the message so no-one else can read it but its intended recipient. But what are these algorithms, how did they come to be widely used, and how secure really are they?
- Encryption definition and meaning
- When you begin to investigate encryption you will find a number of possibly unfamiliar terms. Encryption applications encode data so that it can only be unlocked with a certain key, making it more difficult for third-parties to gain access. Because of this just people who have access to that key can also access the data, making encryption software an important tool for keeping data safe. Encryption is the process of using an algorithm to transform information to make it unreadable for unauthorized users. Encryption is important because it allows you to securely protect data that we don't want anyone else to have access to. Companies use it to protect corporate secrets, governments use it to secure classified information, and many people use it to protect private information to guard against things like identity theft.
- Types of encryption
- Symmetric cryptography: there is a single secret key that is used to encrypt and decrypt. The involved parties share that key, password, or passphrase, and they can use it to decrypt or encrypt any messages they want. This kind of encryption is very good for securing files on a disk. The tricky part of using symmetric encryption is how to store the key and make it available only to the software that needs it.
- Examples of symmetric encryption schemes are the Advanced Encryption Standard (AES), Data Encryption Standard (DES), the International Data Encryption Algorithm (IDEA), etc.
- Asymmetric algorithms: asymmetric keys consist of a public key and a private key. These two keys combine to form a key pair. one to encrypt the message and the other to decrypt it.
- Examples of asymmetric encryption schemes are the Benaloh cryptosystem, Boneh–Lynn–Shacham, RSA (cryptosystem) etc.
- Benefits of encryption
- For example, the encryption on the iPhone is the 256-bit AES standard also used by the US military. If your data isn't encrypted, anyone who happens across your PC or laptop can get at the files within pretty easily, with encryption added, accessing the same data becomes very difficult.
- Which types of encryption are most secure
- AES is fast and works best in closed systems and large databases. PGP should be used when sharing information across an open network, but it can be slower and works better for individual files. If your encryption software uses a recognized and respected standard such as AES or PGP, and you use strong passwords and take other precautions, it almost certainly is.
- Is your data encryption really secure
- There's no such thing as perfect security. Given enough time or processing power, any password can be cracked through a brute force attack. But with a sufficiently strong password, the time and processing power required is just not practical.
- How to keep your data safe
- 1. Backup data: creating copies of data so it can be recovered if the original copy is lost. There are many different ways to backup your computers, and using multiple forms of backup will minimize the risk of ever losing your valuable files (External Hard Drive, USB Flash Drive, DVD, Cloud). The backed up data must be encrypted.
- 2. Data Encryption: by using encryption for data – both at rest and in transit – you can ensure that your information is kept safe and that your staff and customers will be confident that all their details are protected.
- 3. Data Masking: masking certain areas of data so personnel without the required authorization cannot look at it.
- 4. Data Erasure: ensuring that no longer used data is completely removed and cannot be recovered by unauthorized people.
- 5. Password length: for the cipher, the most simple way of attack is brute force, trying each key before the correct one is found. The length of the password determines the number of possible keys to this type of attack. Encryption strength is directly tied to key size, but as the key size increases, so do the resources required to perform the computation.
- Suppose a hacker has a computer that can test a billion keys per second, trying to brute force all combinations. Therefore, the hacker can easily crack a 30-bit key in just one second. At this speed, it will take you a billion seconds (or 34 years) to break a 60-bit key because every 30 bits added makes it a billion times more difficult.
- 6. Monitoring data: if any unauthorized access has occurred. You can quickly follow up and stop access before extensive damage can take place. This way, your sensitive information is likely to remain safe even if your other security efforts prove inadequate.
- idoo File Encryption Software provides the complete range of file encryption, hide, deny read, shredder, and many more. It gives you a unique ability to fully monitor all your files/folders and drives. It gives you exceptional protection in any environment.
- Finally, it's important to remember that Encryption is not a complete security solution and nothing keeps your devices 100 percent protected. But encryption is definitely one of your best friends in the hostile world of digital information.
Keeping your personal data safe doesn't have to be difficult—as long as you keep the sensitive stuff encrypted and under your control.
