# What would be a typical value for the security parameter of the Fully Homomorphic Encryption over the Integers scheme?

The parameters of the Fully Homomorphic Encryption scheme by Dijk et.al are chosen according to the value of the security parameter ${\lambda}$, section 3 of the aforementioned article.

What is the security parameter for this scheme ? It represents the bits of security the scheme has ? If so, what would be a secure value right now ?

• You may like to have a look at the following paper: "Fully Homomophic Encryption over the Integers Revisited". It gives a reduction from AGCD to DLWE and discusses the possible values for parameters of AGCD on Section 2.
