A Reliable Technique for Data Encryption Using Symmetric Approach

Today almost sixty percent of the world is on internet, with online data exchange becoming the most common way of transferring information with each other, it brings with itself a number of security risks to the said data. As per the Identity Theft Resource Centre, up until October, the number of publicly documented data breaches has already exceeded the total for 2020, putting 2021 on track to be a record year. To combat this pressing issue and achieve data security in the most efficient manner our research paper has proposed a model to achieve the same using encryption. It is one of the most reliable approaches to prevent the interference from intruder using a key. The symmetric approach uses a single key which is encrypted by the sender and later decrypted by the receiver. The key is generated using some basic operation such as decimal to binary conversion and vice versa, one's compliment, swapping, concatenation etc. This method encrypts the data and transforms it efficiently, making it difficult to be decoded by an unauthorized user. As it is a very convenient technique, it can easily be used in a number of modern applications to safely store and transfer sensitive data.
