Block Cipher Techniques
Approved Algorithms Currently, there are two (2) Approved* block cipher algorithms that can be used for both applying cryptographic protection (e.g., encryption) and removing or verifying the protection that was previously applied (e.g., decryption): AES and Triple DES. Two (2) other block cipher algorithms were previously approved: DES and Skipjack; however, their approval has been withdrawn. See the discussions below for further information; also see SP 800-131A Rev. 2, Transitioning the Use...
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. Masked Circuits (MC) can be produced by masking schemes, which use secret-sharing of the input bits and recompile the circuit logic to ensure that important properties of the secret sharing remain across the circuit evaluation. The MC project is on hold, but a future step will gather masked circuits. Updates will be announced via the MC-forum. After past exploratory...
Multi-Party Threshold Cryptography MPTC
The multi-party paradigm of threshold cryptography enables threshold schemes, which apply principles of secure multiparty computation (MPC) to achieve protocols that enable a secure distribution of trust in the operation of cryptographic primitives. Threshold schemes can be applied to NIST standardized primitives/schemes, and beyond. The technical scope of the MPTC-project includes threshold schemes (for signatures, public-key encryption/decryption, ciphers, hashing, fully-homomorphic encryption...
