| Quote: | How secure is EV-DO?
Over the years, wireless security has garnered an extremely bad rap—and rightfully so. As the technology developed, a good amount of vulnerabilities and security flaws surfaced.
802.11b, one of the first Wi-Fi standards to become popular almost six years ago, used the wired equivalent privacy (WEP) protocol. But war drivers and other intruders have been able to hack into wireless LANs—not only because of the flaws in WEP, but also because of the poor implementation of authentication and key management that are inherent in the 802.11 standard. (It doesn't help that vendors usually ship WLAN hardware with WEP disabled to make deployment easier.)
But EV-DO doesn't use WEP. Instead, encrypted CDMA transmissions use a 42-bit pseudo-noise (PN) sequence called a long code. The long code scrambles transmissions through the standardized Cellular Authentication and Voice Encryption (CAVE) algorithm to generate a 128-bit subkey called Shared Secret Data (SSD).
This key then feeds into an Advanced Encryption Standard (AES) algorithm to encrypt the transmissions. AES is a symmetric encryption algorithm used by governments to protect sensitive information. If governments use AES to encrypt their data, it should be good enough to protect your data as well. |

There are two modes of security in my view. Protecting monitoring of data transmissions and protecting unauthorized access to the network.
Hacking into access of the network is an issue for the carrier more than for users. For users, if they are concerned about monitoring of tranmissions, they should be doing VPN or some other solution and not depend on the carrier for data security. |

This is what Sprint says about security:
Security: Employs CDMA wireless technology authentication and identification system for top-notch security. The Mobile Identification Number (MIN) and Electronic Serial Number (ESN), together with CDMA spread spectrum technology, make it virtually impossible for unauthorized users to capture and decipher messages and other sensitive information.
