问题
I am working on a encryption algorithm and using cryptography for this. I want to make this portable, but didn't find any way to resolve this class.

You can also use the full managed Bouncy Castle Library. A Portable Class Library Patch is available here: http://www.bouncycastle.org/jira/browse/BMA-107
A pre-build of Bouncy Castle 1.7 with the PCL Patch is available here for example: https://github.com/dnauck/Portable.Licensing/tree/master/lib

You Didn't mention what profile you are looking for
In any case... RNGCryptoServiceProvider it seems to exist only in
.NET Framework Supported in: 4.5, 4, 3.5, 3.0, 2.0, 1.1, 1.0 .NET Framework Client Profile Supported in: 4, 3.5 SP1
As per documentation at RNGCryptoServiceProvider Class
I started dealing with cryptography, with pclContrib but I didn't find it complete enough, basic functionality I needed to calculate some hashes worked fine as far I stick to what pclcomtrib had,
But then it got a little messy with the references in the projects mostly with the Silverlight side because these are adapters PCLContrib FAQ .
I ended up abstracting all the security bits using interfaces within the pcl's where the implementations are platform specific
pretty much the same thing you might face with file access (depends how portable you want to go).
I'm afraid pclcontrib might not be your case too
Portable.Security.Cryptography
System.Security.Cryptography.AesManaged
System.Security.Cryptography.HMACSHA1
System.Security.Cryptography.HMACSHA256
System.Security.Cryptography.SHA1Managed
System.Security.Cryptography.SHA256Managed
System.Security.Cryptography.Rfc2898DeriveBytes
You might want to have a look at the following questions/answers that I think will (indirectly)answer your question.

You may want to check out http://pclcontrib.codeplex.com. It has support for cryptography.
