Cryptography and Encryption
Cryptography is the engagement of codes to protect information from unintended persons. Only the receiver can process and utilize the protected data. Computer science defines cryptography as the engagement of mathematical theories and algorithms to protect information and communication (Antonio et al., 2019). These concepts and algorithms change the information so that only the receiver can decipher it. These techniques are used for the confidential exchange of information and secure browsing of the internet-using public or private browsers. Cryptography entails authentication, non-repudiation, integrity, and confidentiality.
Cryptography is essential in security since it utilizes its codes to safeguard corporations’ communication and information systems from cyber-attacks by engaging the information security technique. Cryptography is vital in information security since it protects the information so that only the intended receiver can access it. Cryptography promotes privacy. It is also relevant to information security because it utilizes digital signatures to hold the sender and receiver accountable for the information. The sender cannot deny its origin, and the receiver cannot deny receiving it.
Implementing cryptography is costly and time-consuming. Conversely, it is essential in eschewing falling victim to cyber-attacks. Organizations employ centralized crypto services to facilitate their management and utilization of cryptography in information security. These organizations utilize cryptography as a service to achieve corporate objectives (Buchanan et al., 2017). Implementation of cryptography requires successful monitoring and logging skills for service usage assessment. Implementation of cryptography enables the company to implement its security policy and reduce the reliance on HSM hardware vendors.
Encryption utilizes scrambling techniques to mix up the data so that unauthorized receivers cannot use the information. Encryption can also be described as the changing user texts that humans understand to a ciphertext incomprehensible by humans. It employs a cryptographic key that is common to the sender and receiver (Ghadirli et al., 2019). Although it is a randomized process, the information follows a predictable pattern that the receiver possessing the cryptographic key can understand. Conversely, this random pattern cannot be understood by a third party since it utilizes complex texts.
Encryption is vital in the security of the information since it ensures there is privacy. It prevents interception and utilization of sensitive information by cyber-criminals or the government. It plays a role in information security by hindering data breaches in an organization or personal files. Encrypting a corporate device’s hard drive secures the data from being accessed even when the device falls into the wrong hands. Furthermore, encryption is essential as an information security technique since it is a requirement by the government, especially for a corporation that handles confidential user information. HIPPA is among the compliance standards that require encryption. Encryptions also maintain security when browsing the internet by securing the requests and responses in the HTTP.
Implementation of encryption involves selecting appropriate algorithms to ensure that the algorithms’ weaknesses do not facilitate a brute-force attack. Using a suitable algorithm will successfully protect the data when the encryption is implemented. Bolstering the information security by implementing encryptions is accomplished by selecting the correct key sizes to be utilized by the algorithms to process and read the encrypted information (Ghadirli et al., 2019). Appropriate software selection and keeping the key secure are the final steps for successfully implementing encryptions. Implementation of encryption is essential in corporations that handle confidential information like financial institutions.
