Implementations

impl LWEKSK

pub fn zero(
    sk_before: &LWESecretKey,
    sk_after: &LWESecretKey,
    base_log: usize,
    level: usize
) -> LWEKSK

Generate an empty LWE key switching key

Argument

• sk_before - an LWE secret key (input for the key switch)
• sk_after - an LWE secret key (output for the key switch)
• base_log - the log2 of the decomposition base
• level - the number of levels of the decomposition

Output

• an LWEKSK

pub fn new(
    sk_before: &LWESecretKey,
    sk_after: &LWESecretKey,
    base_log: usize,
    level: usize
) -> LWEKSK

Generate a valid LWE key switching key

Argument

• sk_before - an LWE secret key (input for the key switch)
• sk_after - an LWE secret key (output for the key switch)
• base_log - the log2 of the decomposition base
• level - the number of levels of the decomposition

Output

• an LWEKSK

pub fn save(&self, path: &str)

pub fn load(path: &str) -> LWEKSK
