PQSDES cipher-hash

PQSDES is a software upgrade to the US NIST DES cipher intended to increase its security, performance and functionality. PQSDES will offer single-pass authenticated encryption and collision resistant hash functionality with security ratings from 10 to 100 years depending on operational parameters. PQSDES is a symbiotic cipher construction that takes advantage of the hardware DES circuitry in smart cards. PQSDES-512 is significantly faster than 3DES-168 for data privacy and message integrity operations on desktops.

PQSAES cipher-hash

PQSAES is a software upgrade to the US NIST AES cipher intended to increase its security and functionality. PQSAES will offer single-pass authenticated encryption and collision resistant hash functionality with security ratings from 10 to 100 years depending on operational parameters. PQSAES is structurally very similar to the PQSDES. Single pass authenticated encryption using PQSAES-512 is estimated to run at approximately the same speed as the weaker standards based combination of AES-256 for data privacy and AES-128-HMAC for message integrity.

Idigram

Idigrams are an innovative symmetric technique that can be applied in at least two different contexts.  In the first context Idigrams can be used to improve the performance and security characteristics of symmetric key exchange operations. In the second context Idigrams can be used to provide long term high assurance data integrity assurances more efficiently than Lamport-Diffe-Merkle digital signatures.

VEST cipher-hash

VEST is a family of hardware dedicated ciphers designed exclusively for FPGA and ASIC application. VEST offers security ratings ranging from 80-bit to 256-bit post quantum secure. VEST is a conservative hardware design capable of single-pass authenticated encryption and collision resistant hashing operations. First published in 2005, the full specifications to VEST v2.1 (2007) are available online.
