With the rise in online money transactions worldwide from recharging your mobile balance to purchase or money transfer of thousands of rupees. We should aware of online ‘thugs’. Recent study shows that every online user owes 2.80 $ to the hackers so we should know that how different mobile apps, websites try to protect our transaction details from the hackers.
Ø ITS ALL ABOUT AES AND RSA.
These are nothing but the encryption techniques. The most commonly used is the AES ( Advanced Encryption Standards),AES-128,192, and 265 for governments, banks and other popular apps.
Encryption systems are of two types
2. Public –key
In symmetric –key encryption ,two communicating computers have a secret key which is used to encrypt the code . and believe me AES-128 bitkey for instance can have more than 300,000,000,000,000,000,000,000,000,000,000,000. Key combinations and cracking it with a state-of-the-art supercomputer would take longer than the presumed age of the universe i.e 4500 million years. And current systems uses AES-256 so its impossible to crack AES-256.
Ø IT’S Algorithm.
The algorithm is based on several substitutions, permutations and linear transformations which creates 16 byte block. Operations are repeated several timesand results into ‘rounds’. During each round a unique key is calculated out of the encryption key, and incorporated in the calculations.
