Entropy as a Service EaaS
Cryptography is critical for securing data at rest or in transit over the IoT. But cryptography fails when a device uses easy-to-guess (weak) keys generated from low-entropy random data. Standard deterministic computers have trouble producing good randomness, especially resource-constrained IoT-class devices that have little opportunity to collect local entropy before they begin network communications. The best sources of true randomness are based on unpredictable physical phenomena, such as...
Masked Circuits for Block-Ciphers
A main goal of circuit masking is to make more difficult the illegitimate exfiltration of secrets from a circuit evaluation. Masking schemes use secret-sharing of the input bits of a circuit and recompile the circuit logic to ensure that important properties of the secret sharing remain across the circuit evaluation.

Multi-Party Threshold Cryptography MPTC
The multi-party paradigm of threshold cryptography enables a secure distribution of trust in the operation of cryptographic primitives. This can apply, for example, to the operations of key generation, signing, encryption and decryption. This project focuses on threshold schemes for cryptographic primitives: using a “secret sharing” mechanism, the secret key is split across multiple "parties"; if some (up to a threshold f out of n) of these parties are corrupted, the key secrecy remains...
Random Bit Generation RBG
Include revised/updated text from  http://csrc.nist.gov/groups/ST/toolkit/rng/index.html ??   --> Cryptography and security applications make extensive use of random numbers and random bits. However, constructing random bit generators and validating these generators are very challenging. The SP 800 90 series provides guidelines and recommendations for generating random numbers for cryptographic use, and has three parts: SP 800-90A, Recommendation for Random Number Generation Using...
