Among the plethora of data security strategies, encryption has been rapidly making a name for itself as one of the best solutions. However, keep in mind that when it comes to encryption solutions, there is no one-size-fits-all strategy. If you are thinking of incorporating this technique into your security strategies, brush up on this basic knowledge.
Types of Encryption
The two most commonly used types of encryption solutions are symmetric and asymmetric. Symmetric encryption uses the same key for encryption and decryption. Asymmetric encryption, on the other hand, uses a public key to encrypt the data and a private key to decrypt it.
The keys in symmetric encryption are relatively short, making it faster and more efficient. Additionally, using the same key to encrypt and decrypt adds to its speed advantage. Because of these features, symmetric encryption can handle much more data at any given time.
What sort of data is your team working with? If you are dealing with large files, this method will work well for your team. Extensive processes and additional memory is not needed, thanks to the efficiency and ease of symmetric encryption.
On its downside, symmetric encryption works with the assumption that both parties will use the same key. In order to ensure this key is understood between each party, the key needs to somehow be communicated between them. If the key is intercepted by digital means, the symmetric encryption solution will fail.
Asymmetric encryption solutions are more complex, making additional processors and memory a necessary component. Only the user that generates the private and public key pair will have access to both. That user will then distribute the public key to anyone that wishes to send encrypted data to them.
One downside to this method is it is an entirely one-sided process. Only one sender is able to receive messages from others, but that one sender cannot send messages back using the same technique.
If you need to identify or authenticate sensitive documents, asymmetric encryption is the best solution. This method is great for authenticating data through digital signatures.
