What is the goal of cryptosecurity?

• A. Providing technically sound cryptosystems and properly using them
• B. Increasing data rates
• C. Reducing power consumption
• D. Physical security of equipment

Answer: (A)

Cryptosecurity aims to protect information by applying cryptographic techniques and using them correctly. It isn’t enough to have strong algorithms; security also depends on proper key management, good randomness, correct implementation, and appropriate protocols so confidentiality, integrity, and authenticity are preserved. A robust cryptosystem used poorly or misconfigured can still be vulnerable, which is why the goal includes both sound design and proper deployment. The other options miss this core aim: they emphasize performance, power, or hardware protection, rather than the cryptographic protections and correct usage that truly safeguard data.
