ECFieldF2m(Int32)

Creates an elliptic curve characteristic 2 finite field which has 2^m elements with normal basis.

[Android.Runtime.Register(".ctor", "(I)V", "")]
public ECFieldF2m (int m);

[<Android.Runtime.Register(".ctor", "(I)V", "")>]
new Java.Security.Spec.ECFieldF2m : int -> Java.Security.Spec.ECFieldF2m

Parameters

m

Int32

with 2^m being the number of elements.

Attributes

RegisterAttribute

Exceptions

IllegalArgumentException

if m <= zero.

Remarks

Creates an elliptic curve characteristic 2 finite field which has 2^m elements with normal basis.

ECFieldF2m(Int32, BigInteger)

Creates an elliptic curve characteristic 2 finite field which has 2^m elements with polynomial basis.

[Android.Runtime.Register(".ctor", "(ILjava/math/BigInteger;)V", "")]
public ECFieldF2m (int m, Java.Math.BigInteger? rp);

[<Android.Runtime.Register(".ctor", "(ILjava/math/BigInteger;)V", "")>]
new Java.Security.Spec.ECFieldF2m : int * Java.Math.BigInteger -> Java.Security.Spec.ECFieldF2m

Parameters

m

Int32

with 2^m being the number of elements.

rp

BigInteger

the BigInteger whose i-th bit corresponds to the i-th coefficient of the reduction polynomial.

Attributes

RegisterAttribute

Exceptions

IllegalArgumentException

if m <= zero or the rp is invalid.

Remarks

Creates an elliptic curve characteristic 2 finite field which has 2^m elements with polynomial basis. The reduction polynomial for this field is based on rp whose i-th bit corresponds to the i-th coefficient of the reduction polynomial.

Note: A valid reduction polynomial is either a trinomial (X^m + X^k + 1 with m > k >= 1) or a pentanomial (X^m + X^k3 + X^k2 + X^k1 + 1 with m > k3 > k2 > k1 >= 1).

ECFieldF2m(Int32, Int32[])

Creates an elliptic curve characteristic 2 finite field which has 2^m elements with polynomial basis.

[Android.Runtime.Register(".ctor", "(I[I)V", "")]
public ECFieldF2m (int m, int[]? ks);

[<Android.Runtime.Register(".ctor", "(I[I)V", "")>]
new Java.Security.Spec.ECFieldF2m : int * int[] -> Java.Security.Spec.ECFieldF2m

Parameters

m

Int32

with 2^m being the number of elements.

ks

Int32[]

the order of the middle term(s) of the reduction polynomial. Contents of this array are copied to protect against subsequent modification.

Attributes

RegisterAttribute

Exceptions

IllegalArgumentException

if m <= zero or the reduction polynomial is not valid.

Remarks

Creates an elliptic curve characteristic 2 finite field which has 2^m elements with polynomial basis. The reduction polynomial for this field is based on ks whose content contains the order of the middle term(s) of the reduction polynomial. Note: A valid reduction polynomial is either a trinomial (X^m + X^k + 1 with m > k >= 1) or a pentanomial (X^m + X^k3 + X^k2 + X^k1 + 1 with m > k3 > k2 > k1 >= 1), so ks should have length 1 or 3.
