The Most Secured Types of Encryption

A secure encryption is very essential to protect online platforms. There are various kinds of encryption.

There are three fundamental encryption types with varying uses. Symmetric encryption allows for the protection of data at rest on a device or in the cloud. It is by far one of the simplest yet the strongest form of encryption which uses a symmetric key for data at rest in a computer or in the cloud. Its keys are generally 128 or 256 bits long. Symmetric encryption means that it uses the same key to encrypt the original text resulting to an unreadable cyphertext and decrypted original text.

Symmetrical encryption is limited in its use in a way that algorithms such as AES are unable to expertly share information across a network spanning various and multiple parties. During times when a big number of people need to access the same data, there has to be a way to distribute the keys without the danger or fear of it being intercepted.

Due to this limitation, there is a difficulty in using symmetric encryption when working across a big network since there is generally an absence of secure ways to transmit the key across the whole network without the presence of another layer of encryption. Furthermore, with symmetric encryption, only the user has access to the key and not the original creator of the device or the algorithm, thus when the password is accidentally forgotten, or the key is lost, then the encrypted data will most probably become undiscoverable.

Asymmetric encryption, on the other hand, protects data in motion during transmission, since symmetric encryption has limitations in sending data across the network, asymmetric data can protect data while it is in motion. It uses a pair of keys with a public key and a private key. Asymmetric encryption is used in a variety of ways, to establish a safe and secure connection along with encrypting emails.

BSA The Software explains that nonetheless, asymmetric encryption technologies also have its own limitation as it can become very vulnerable to “man-in-the-middle attacks” characterized by a bad actor giving the same public key to two recipients each thinking that the key is exclusively theirs. Thus, the bad actor has the ability to be in the middle of the conversation, effectively decrypting information from the middle before it is passed along.

These challenges can be overcome, and ways can be taken in order to ensure that the correct public key is being used and that the keys are distributed to verified and legitimate entities using a trusted software. Secure websites, for example, need to obtain a certificate from their own HTTPS server which in turn comes from a trusted certificate authority. Due to the permission is given by certificate authorities for browsers by signing keys, websites are then able to send public keys allowing the web browser to know that they can indeed trust the public key and thus effectively initiate a secure connection.

Authenticating a person, device or computer is the process of reassuring that the people on both ends of a process are legitimate. Hashing is one essential technology to protect passwords. It is a very common technique to protect passwords when a website is hacked and attacked by cybercriminals.

Specific examples of encryption include:

TRIPLE DES

Triple DES is designed to replace the original Data Encryption Standard (DES) algorithm since hackers eventually learned to defeat the previous one with relative ease. Triple DES is the newly recommended standard and is considered the most widely used symmetric algorithm in the industry.

RSA

RSA is considered the standard for encrypting data on transit being sent and received over the internet. RSA is considered asymmetric since it employs a pair of keys. The resulting product of an RSA encryption is very difficult to understand and comprehend for attackers.

TWOFISH

Twofish is the successor of the older Blowfish, it was considered by the US government in finding its cryptographic standard. It is a very flexible algorithm that works really well with smaller sized computers and it comes with free licensing and copyright for all users.

AES

Advanced Encryption Standard (AES) is highly resilient against known attacks; it is used by the US government since its encryption is very useful for protecting classified information.

These kinds of encryption are indeed very important in protecting data privacy and consequently maintaining safety and security of a wide array of institutions and industries’ data, thus it will never hurt to research on these and employ the best program to enjoy all the perks and pleasures of encryption.

Protect your Data Using an Encrypted USB

Encryption is a very useful method to protect data stored on portable devices such as external hard drives and USB flash drives. These devices are very essential in storing memory and data, especially for individuals. With encryption, only the person or the owner who is in possession of the accurate encryption key can decode it. Thus, when the situation arises resulting in the loss of these devices when the user is able to encrypt data with a USB key, it cannot be accessed or used by unauthorized users.

There are many types of USB flash drive.

USB 1.1 is the earliest version which has the purpose of supporting devices at a lower speed such as mouse and keyboard. Depending on the devices, it can operate in two modes, the low-speed mode, and the full speed mode. The low-speed mode allows data transfer at 1.5 Mbps while the high-speed mode allows data transfer at 12 Mbps.

USB 2.0, on the other hand, is the newer version. It supports devices faster but the device has to be designed for USB 2.0 such as flash drives and hard disks. With the USB 2.0 data is transferred faster at 480 Mbps.

USB 3.0 is ever faster and newer, operating are super speed featuring data transfer modes that can reach up to 5 Gbps. Most devices today are eligible and ready with a system which supports USB 3.0

Using a USB Flash Drive has many advantages such as its convenience since it is extremely small and therefore can fit in the user’s pocket or purse, very convenient for transporting, it does not contain any moving parts thus it is very durable and long lasting, USB flash drives’ storage is ever increasing with its price also decreasing, it is widely supported by many computer systems and it uses considerably less power compared to external hard drives.

According to Symantec’s How Drive Encryption Works, there are various strategies when encrypting data and assuring that it’s privacy is maintained. With drive encryption, disks can be protected in cases of qualified theft or incidental loss as it encrypts the whole disk along with the system files, swap files, and hibernation files. If the encrypted disk has been lost or stolen and inserted into another computer, the encryption remains intact to assure that only the authorized owner or user can access the contents.

Nevertheless, drive encryption cannot protect the data when the user has logged in into a system during startup and has consequently left the computer unattended. During these cases, the encrypted system has been unlocked, thus unauthorized users now have the ability and capacity to access the system. File encryption is most useful in these situations as it provides an additional layer of security in cases when the drive encryption has been breached.

The steps in encrypting a USB can be done in just a few simple steps. First, the USB flash drive must be inserted, open My Computer of Windows Explorer, right click on the flash drive and select Turn on BitLocker from the menu. After the BitLocker has prepared the flash drive, the wizard will then prompt the user to choose how you want to unlock the device, passwords will allow the drive to be unlocked in any location and to be shared with certain people. The wizard will then prompt the user to store a recovery key in case the user forgets the password, the recovery key must not be saved on the flash drive you are encrypting. The user will then click on the save the recovery key to a file and in the save BitLocker recovery key as dialog, the user must then browse to a suitable location then click Save. Click next. Then click Start Encrypting. The user must not remove the USB flash drive until the encryption process is complete.

In the year 2013, the encryption algorithm has shown much development with features such as Advanced Encryption 256. AES 256 is used in order to meet the Federal Information Standard 140 which requires level 2. Encryption is continuously developing and improving throughout the years, coming out every year with new features and breakthrough innovations.

An encrypted flash drive is very essential in order to assure the protection of a USB flash drive especially if it is used to store very important and private data. Users should take steps to encrypt data with a USB key to avoid unauthorized use of information from flash drives.…
