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 Two (2) other block cipher algorithms were previously approved: DES and Skipjack; however, their approval has been withdrawn.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. 1, Transitions:...
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. At this stage, the Masked Circuits (MC) project is not considering actions toward standardization. However, there is a plan to create a library of masked circuits (specified at the...
Multi-Party Threshold Cryptography MPTC
The multi-party paradigm of threshold cryptography enables threshold schemes, for a secure distribution of trust in the operation of cryptographic primitives. New (2023-Jan-25): NIST IR 8214C ipd: NIST First Call for Multi-Party Threshold Schemes (initial public draft). DOI: 10.6028/NIST.IR.8214C.ipd. Public comments due 2023-Apr-10 (there is a suggested template). Upcoming (1st half of 2023): NIST IR 8214B (final) — Notes on Threshold EdDSA/Schnorr Signatures (To publish after revising its...
