This definition does well to capture the importance of cryptography. I appreciate how you addressed the three fundamental security goals it provides—confidentiality, integrity, and authenticity. You also well identified its real-world applications, from password encryption to online transactions and digital signatures. I am glad you brought compliance and customer trust to the fore because cryptography is a key ingredient towards attaining data protection mandates and maintaining a company’s good reputation. Your abstract points out that cryptography is not a technological buzzword but, instead, is a cornerstone of modern data security that makes sensitive data trustworthy and safe from start to finish.
