HEQueryCountMaster {distcomp} | R Documentation |

## Create a homomorphic computation query count master object to employ worker objects generated by `HEQueryCountWorker()`

### Description

`HEQueryCountMaster`

objects instantiate and run a distributed homomorphic query count computation; they're instantiated by non-cooperating parties (NCPs)

### Super class

`distcomp::QueryCountMaster`

-> `HEQueryCountMaster`

### Public fields

`pubkey`

the master's public key visible to everyone

`pubkey_bits`

the number of bits in the public key (used for reconstructing public key remotely by serializing to character)

`pubkey_n`

the

`n`

for the public key used for reconstructing public key remotely`den`

the denominator for rational arithmetic

`den_bits`

the number of bits in the denominator used for reconstructing denominator remotely

### Methods

#### Public methods

## Inherited methods

#### Method `new()`

Create a new `HEQueryCountMaster`

object.

##### Usage

HEQueryCountMaster$new(defn, partyNumber, debug = FALSE)

##### Arguments

`defn`

the computation definition

`partyNumber`

the party number of the NCP that this object belongs to (1 or 2)

`debug`

a flag for debugging, default

`FALSE`

##### Returns

a new `HEQueryCountMaster`

object

#### Method `setParams()`

Set some parameters of the `HEQueryCountMaster`

object for homomorphic computations

##### Usage

HEQueryCountMaster$setParams(pubkey_bits, pubkey_n, den_bits)

##### Arguments

`pubkey_bits`

the number of bits in public key

`pubkey_n`

the

`n`

for the public key`den_bits`

the number of bits in the denominator (power of 2) used in rational approximations

#### Method `kosher()`

Check if inputs and state of object are sane. For future use

##### Usage

HEQueryCountMaster$kosher()

##### Returns

`TRUE`

or `FALSE`

#### Method `queryCount()`

Run the distributed query count, associate it with a token, and return the result

##### Usage

HEQueryCountMaster$queryCount(token)

##### Arguments

`token`

a token to use as key

##### Returns

the partial result as a list of encrypted items with components `int`

and `frac`

#### Method `cleanup()`

Cleanup the instance objects

##### Usage

HEQueryCountMaster$cleanup()

#### Method `run()`

Run the homomorphic encrypted distributed query count computation

##### Usage

HEQueryCountMaster$run(token)

##### Arguments

`token`

a token to use as key

##### Returns

the partial result as a list of encrypted items with components `int`

and `frac`

#### Method `clone()`

The objects of this class are cloneable with this method.

##### Usage

HEQueryCountMaster$clone(deep = FALSE)

##### Arguments

`deep`

Whether to make a deep clone.
