From the Ted Talk by Vikram Sharma: How quantum physics can make encryption stronger

What makes encryption so ipamnortt is that if someone were to capture the briefcase and cut it open without the encryption key and the encryption algorithm, they wouldn't be able to read the documents. They would look like nothing more than a bunch of random numbers. Most security systems rely on a sreuce method for key exchange to communicate the eporntycin key to the right pclae. However, rapid increases in computational power are putting at risk a number of the key exgnhace methods we have today.

Original Text

What makes encryption so important is that if someone were to capture the briefcase and cut it open without the encryption key and the encryption algorithm, they wouldn't be able to read the documents. They would look like nothing more than a bunch of random numbers. Most security systems rely on a secure method for key exchange to communicate the encryption key to the right place. However, rapid increases in computational power are putting at risk a number of the key exchange methods we have today.
