Authentication of iPhone OS

For Wireless Network WPA2 Enterprise

Encryption of iPhone OS

Hardware encryptionAES 256 bit encoding

Internet encryptionSSL v3TLS v1

Data encryption128-bit AES encryption

Strengths of iPhone OS

Objective-C, simple language to learn and use

Huge amount of apps Accessible by everyone (e.g.

VoiceOver) Multi-Touch interface

Weaknesses of iPhone OS

NOT support Flash

Safari NOT support Java

Only one carrier

Deleted data vulnerable to hacker

BlackBerry OS

Authentication of BlackBerry OS

BlackBerry devices are content servers directly

Most of the data are in the BlackBerry server but not device

BlackBerry MDS Connection Service authenticates to content servers on behalf of BlackBerry devices

Data will not leakage easily

Encryption of BlackBerry OS

Data and message will encrypt by using Enterprise Server Express before sent

AES / Triple Des data encryption method are used in the transmission process

Decryption will be done after arrive terminal device

Strengths of BlackBerry OS

Safety and convenience mail communication

classification of the five programs navigation bar are useful and better then old interface

WebKit browser engine improve the browsing efficiency

with more social networking tools, allowing you to combine email, Facebook and Twitter updates all in one place

Delete SurePress function to simply the usage

Weaknesses of BlackBerry OS

Number of Apps are still far behind user needs(BlackBerry: over 8000; Android: 70000; iPhone: 220000)

New OS have no outstanding function compare to other OS

Still do not support Flash

Android OS

Authentication & Encryption in Android OS

Most Android applications use self-signed certificates still does not support hardware-based encryption Open-source

Weakness Easier for hacker to take data off a Micro SD card Hacker can understand the underlying

architecture and source code Cybercriminals will be rushing to take advantage

Authentication & Encryption in Android OS

Strengths Developing enterprise encryption solutions for

data Enforcing standard security policies User administration for predefined Active

Directory and/or LDAP groups Remote application installation

remote lock remote wipe advanced password rules

More secure faster than a close OS

Strengths of Android

Lies in the future

Strengths of Android OS

Roadmap of Android OS cost of innovation is borne largely by

Google

Versatility

Gathered up a group of some like minded partners

Weaknesses of Android OS

Apps don’t look as sexy as the iPhone ones

Inability to download apps to your micro SD card

Competing against one another for shelf-space instead of the iPhone

Window Mobile OS

Authentication of Window Mobile

Windows Mobile 5.0uses ActiveSync desktop to connect

to the corporate CA to receive the required user certificate and associated key

Windows Mobile 6 implementing Transport Layer

Security (TLS) certificate-based authentication

Encryption of Window Mobile

Windows Mobile 6.1 supports AES 128 Encryption for On Device Encryption.There is no way to export the

Encryption KeyThe Encryption Key Changes on Hard

ResetDevice encryption can only be

enabled via a security policy there is no way a user can enable this feature in Windows Mobile.

Encryption of Window Mobile

Windows Mobile 6.0 onward supports AES 128 Encryption for files written to the SD card.There is no way to export the

Encryption KeyThe Encryption Key Changes on

Hard Resett

Strengths of Window Mobile

Available apps: bringing apps into one central location

User interface: turn into a user customizable dream

interface Computer desktop integration:

integrate with both Exchange Servers and with Outlook environments

Weaknesses of Window Mobile

There's no copy and paste functionality.

The OS doesn't support multitasking.

There's no Flash support.

The chosen platform

Reasons

Safety and convenience mail communication management of logistic need fast and secure

WebKit browser engine improve the browsing efficiency convenience to check the stock

With more social networking tools well communication

Recommendations

Invite more programmers to create more applications

Concentrate to develop in an unique function

Develop new technology to support more medias, such as Flash
