PRF_128BitL(TUint, const TDesC8 &, const TDesC8 &)

HBufC8 *	PRF_128BitL	(	TUint	aBitLength,
			const TDesC8 &	aKey,
			const TDesC8 &	aIV
		)	[pure virtual]

This function is called by SRTP for key derivation operation (PRF_n) regardless of the algorithm, the default is AESCM-128 Produces key stream based on input key and IV value. PRF_n function is used to derive session key from desired master key.

Parameters

TUint aBitLength	Encryption key length
const TDesC8 & aKey	Input key.
const TDesC8 & aIV	Integer Value (IV). Returns HBufC8* keystream
