I am trying to implement an IEEE Paper In Cryptography. I read many reference regarding an RSA key generation. But i am confused with above statement. Please someone explain me What it says with example.
EDIT *
I am trying to implement key generation from the paper Key-Aggregate Cryptosystem for Scalable Data Sharing in Cloud Storage. In the paper, the first step in key generation is a setup phase state as follows SETUP(1^λ) : Randomly pick a bilinear group G of prime order p where , a generator gϵG ...
In the definition I understand what is meant by bilinear, prime order and generator. But what is that parameter λ and what should its value be?
