In the subject of Cryptography, Find a product or system that manipulates secret data, Give a short Summary of the technology\'s security focusing on issues surrounding side-channel attacks. State potential defenses they could use or have. Explain why the security goals are important.

Solution

Side channel attacks are performed based on the information obtained from the physical implementation of the system. Attacks can be based on obtaining information about signal timings, power consumption or noise.

One system that manipulates secret data and prevents side channel attack is white box cryptography. The main focus of this is to protect the encryption key by obfuscating it. In white box cryptography, operations on the secret key are combined with random data such that the random data cannot be distinguished from the key. Given the cryptographic cipher and key, white box algorith generates code for an application which is semantically same, but difficult to recover the key which is embedded in the code.

The security goals are very important to prevent attackers from accessing sensitive or classified nformation. The goal is to protect the data from unauthorized viewing and also to prevent tampering of sensitive, critical information.
