Tags: See more , See less 8 Answer Add Tags Answer Interview Answer 1 Answer ▲ 0 ▼ If the encryption is unique for each customer then the CDN will not be able to accelerate downloads as each bit delivered to the customer will be unique. However, if there is a trust relationship between the client and the CDN then you could use an encryption key that is shared by the client and the CDN to satisfy the encryption of files at rest, and the CDN edge can then use an SSL tunnel to deliver a unique encryption during transfer.
