Abstract: Systems and methods for authentication and key agreement are provided and can utilize a scheme that uses dynamic key generation to achieve replay-attack resistance in zero round trip time (0-RTT). The hash-chain concept can be integrated with the Diffie-Hellman (DH) key exchange scheme. With this scheme, a device can securely determine the new shared key immediately (i.e., in 0-RTT) and start using it.

Abstract: A cost-effective and reliable digital forensics framework is provided by exploiting multiple blockchain networks in two levels. The selected data collected from sensors on a boat is sent to a remote company database and calculated hash of the data is saved in two blockchain platforms in the first level. Hash of each block is retrieved and inserted onto a Merkle tree on a periodic basis to be stored on another blockchain in the second level which is used to detect any error in the first level blockchains. A secure platform is created with the combination of several blockchains.

Abstract: Systems and methods for certificate revocation management for advanced metering infrastructure networks are provided. An accumulation manager can be used to accumulate certificate revocation list (CRL) information and determine an accumulator value and a proof value based on the accumulated CRL information using a plurality of functions. These values can be sent on to smart meters, which can then use them for authentication purposes.
