An interesting article from HackersNewsBulletin.com:

According to Microsoft, they have earned a key government accreditation called FIPS 140-2—Which is an U.S. government security standard used to accredit the cryptographic algorithms that protect sensitive data inside products like smartphones.

All of the Windows 8 phones received accreditation for nine cryptographic certificates:

• Kernel Mode Cryptographic Primitives Library (CNG.SYS)
• Cryptographic Primitives Library (BCRYPTPRIMITIVES.DLL)
• Enhanced DSS and Diffie-Hellman Cryptographic Provider (DSSENH.DLL)
• Enhanced Cryptographic Provider (RSAENH.DLL)
• Boot Manager
• BitLocker Windows OS Loader (WINLOAD)
• Code Integrity (CI.DLL)
• BitLocker Windows Resume (WINRESUME)
• BitLocker Dump Filter (DUMPFVE.SYS)

This certificate is said to be ‘to protect sensitive data’ while Anonymous group of hackers think that this could be a step to spy, One of the famous Anonymous twitter account (@youranonnews) tweeted ‘Each unit comes with a free back door!!‘

Last year, a few of the Samsung devices have also received the same  FIPS 140-2 certificate and and BlackBerry earned it for the BlackBerry 10 platform back in November last year before it even launched.
