How secure is the data deposit form?

The transmission of files from your computer to ICPSR over the Hypertext Transfer Protocol (HTTP) is encrypted using Secure Socket Layer (SSL) Version 3 with CAMELLIA_256_CBC, SHA1 for message authentication, and DHE_RSA for the key exchange mechanism. Upon receipt, ICPSR encrypts the files using AES-256 encryption and writes them to a secure location on our web server. Once every minute, a process at ICPSR checks the web server for incoming files, moves them onto a server behind our firewall, and deletes the copy on the web server.
