Cryptographic communications using pseudo-randomly generated cryptography keys

TL;DR: In this article, a key management scheme for distributed sensor networks is proposed, which assumes a revocation phase for removal of the key ring of the compromised sensor node from the network and re-keying phase for removing those keys with the expired lifetime.

TL;DR: In this paper, a method and apparatus for secured storage and communication of data using in situ cryptographic key generation facilities was proposed, whereby data to be stored in a data storage system (e.g., a Storage Area Network) can be encrypted using encryption keys that are generated by locally deployed cryptographic key generators, which generate encryption keys based upon setup configurations that include time or event memory data.

TL;DR: In this paper, the pseudorandom number generator generates a random number that is mapped by the mapping system to an output value that is selected from a set of predetermined output values.

TL;DR: In this article, the authors provided a highly secure cryptographic processing apparatus and method where an analysis difficulty is increased by increasing the minimum number (a robustness index against a differential attack in common key block encryption) of the active S box in the entire encryption function.

TL;DR: In this paper, a method and system for encryption services can be added to an existing wireless two-way alphanumeric pager network by providing a pager proxy which is arranged to receive an encrypted message from a sending pager and re-package it for re-transmission to the destination pager.

TL;DR: In this paper, a hierarchical cryptographic system has distributed authority among different classes of units in the system, and the system may comprise a trusted authority, a first unit authorized by the trusted authority to distribute public and private signature and encryption keys, and a second unit accepts for use one or more of the keys only after performing a verification program using the public signature key.

TL;DR: In this article, a storage apparatus includes a key management unit for managing an individual key unique to the apparatus and a common key shared with other storage apparatuses, and an encryption unit for performing an encrypting process or verifying data for performing the encryption process on electronic data stored in the apparatus to which the unit belongs using the individual key, and performing the encrypted data on the electronic data transmitted to or received from another apparatus using the common key.

TL;DR: In this paper, the authors describe a method for enabling users of a cryptosystem to agree on secret keys, and present a hardware and software key exchange protocol based on these two techniques.
