Bit Encryption

The invention of the internet brought to the technical world novel levels of security necessitation to safeguard data from unauthorized access. Encryption, one of the security techniques, refers to a process of hiding the contents of a message, text, or data in ways that cannot be understood unless the party accessing the information has the corresponding decryption capability. The first data encryption approach was the 1970, 56 bit Data Encryption Standard (DES). The innovation was responsible for making common the use of public keys between two or more hybrid systems. The internet in its dynamicity over the years led to the development of wireless network technologies that necessitate further advancements in encryption. Revolution shifted from 40, 56, and 128, 192 to 256-bit encryption standards. The 128-bit key is the most popular encryption model employed in online browsing in the current technology market.

The 128-bit key refers to a cipher that has 128 zeros and ones variables in its code. In cryptography, a key represents a long sequence of ones and zeros (bits) that are used by the decryption and encryption algorithms to hide and unhide text contents (Mitchell, 2013). For instance, a 40-bit key is a practical sequence of zeros and ones all summing up to forty numerals. In cryptography, the premise is that the bigger the numeral sequence, the less the probability of the message content to be accessed without authority. In encryption/decryption, a cipher understands that to modify or access an original message; all keys have to be tried or be compatible with the algorithm. Given that the key has 128 bits, it means that the key is of size 2¹²⁸ (Mitchell, 2013)^. The user has to try more than half of these keys, thus unauthorized access is impossible under contexts of luck. In terms of modern software security, 128-bit encryption is one of the strongest techniques, but not the best.

There is no concept of absolute security when it comes to information systems. Technology is a field characterized by short-term requirements and high levels of advancements. Novel innovations in E-Commerce put 128 key bits as not the most secure prompting the integration of 256-bit key algorithms. 256 bits offer stronger degrees of security in the protection of sockets. The technology offers an additional layer of encryption that not only enhances security but also improves the speed of the internet service provider (Chatterjee & Sarkar, 2011). Despite 256-bit key encryption offering greater safety, it is not yet the set cryptography standard in the current market. This means the 128 key bit algorithm still has some years of being the common security method.

Government agencies and corporations have higher levels of encryption security when compared to 128 key bit technologies. Private and public corporations have greater risks and liabilities in the event of unauthorized access given the nature and importance of their data (Chatterjee & Sarkar, 2011). Moreover, these companies integrate more complex information systems when compared to that of the average home or cyber users. The forms of attacks that attempt to access corporate files are also more complex meaning 128 key algorithms would be insufficient in safeguarding data. Effective security is dependent on the nature of the user, his requirements, operations, and integrated technology. In meaning, the higher the level of liability the user has, the stronger the security.
