CowGear, more protocols with replicated secret sharing

• CowGear protocol (LowGear with covert security)
• Protocols that sacrifice after than before
• More protocols for replicated secret sharing over rings
• Fixed security bug: Some protocols with supposed malicious security wouldn't check players' inputs when generating random bits.

BMR, Use your Brain, Semi/Semi2k

• Complete BMR for all GF(2^n) protocols
• Use your Brain!
• Semi/Semi2k for semi-honest OT-based computation
• Branching on revealed values in garbled circuits
• Fixed security bug: Potentially revealing too much information when opening linear combinations of private inputs in MASCOT and SPDZ2k with more than two parties

MASCOT and SPDZ2k

• SPDZ2k
• Integration of MASCOT and SPDZ2k preprocessing
• Integer division

Matrix multiplication and quantization

• Optimized matrix multiplication
• Data type for quantization as in Tensorflow Lite
• Extended compatibility with macOS
