class SecureFloat(SecureNumber) |
| |
SecureFloat(value=None)
Base class for secure (secret-shared) floating-point numbers.
Basic arithmetic +,-,*,/ and comparisons <,<=,--,>,>=,!= are supported for secure floats,
as well as input()/output() and sorting operations like min()/argmax()/sorted().
Other operations like sum()/prod()/all()/any()/in_prod() are currently not supported for
secure floats.
Implementation is kept simple, representing a secure float as a pair consisting of
a secure fixed-point number for the significand and a secure integer for the exponent.
Note, however, that even basic arithmetic +,-,*,/ with secure floats is very
demanding performance-wise (due to dependence on secure bitwise operations).

Methods inherited from mpyc.asyncoro.SecureObject:
- __array_function__(self, func, types, args, kwargs)
- Redirect __array_function__ call to array class, if any.
To support calls like np.block([[secint(9), -1], [1, secint(7)]]).

class SecureIntegerArray(SecureArray) |

SecureIntegerArray(value=None, shape=None)
Base class for secure (secret-shared) integer arrays.

- Method resolution order:
- SecureIntegerArray
- SecureArray
- mpyc.asyncoro.SecureObject
- builtins.object
Methods defined here:
- __init__(self, value=None, shape=None)
- Initialize a secure integer array to the given value.
If value is None (default), shape must not be None.
The given value must be array of the appropriate type (int/finite field array).
The given shape must be a (possibly empty) tuple of nonnegative integers.

- argmax(self, *args, **kwargs)
- Returns the indices of the maximum values along an axis.
If no axis is given (default), array is flattened first.
By default, the indices are returned as unit vectors.
Also, by default, the maximum values are returned (next to the indices).
NB: Different defaults than for np_argmax(). Latter behaves like np.argmax()
for NumPy arrays, returning the indices as numbers and omitting the maximum values.
- argmin(self, *args, **kwargs)
- Returns the indices of the minimum values along an axis.
If no axis is given (default), array is flattened first.
By default, the indices are returned as unit vectors.
Also, by default, the minimum values are returned (next to the indices).
NB: Different defaults than for np_argmin(). Latter behaves like np.argmin()
for NumPy arrays, returning the indices as numbers and omitting the minimum values.
- copy(self, order='C')
- flatten(self, order='C')
- reshape(self, *shape, order='C')
- sort(self, *args, **kwargs)
