The INT-RUP Security of OCB with Intermediate (Parity) Checksum

OCB is neither integrity under releasing unvierified plaintext (INT-RUP) nor nonce-misuse resistant. The tag of OCB is generated by encrypting plaintext checksum, which is vulnerable in the INT-RUP security model. This paper focuses on the weakness of the checksum processing in OCB. We describe a new notion, called plaintext or ciphertext checksum (PCC), which is a generalization of plaintext c...

Secure & Lightweight Distance-Bounding

Distance-bounding is a practical solution aiming to prevent relay attacks. The main challenge when designing such protocols is maintaining their inexpensive cryptographic nature, whilst being able to protect against as many, if not all, of the classical threats posed in their context. Moreover, in distancebounding, some subtle security shortcomings related to the PRF (pseudorandom function) ass...

Lightweight Secure Group Communication

An advantage of today’s high speed networks is the ability to support group communication. Applications that support group communication allow the free exchange of ideas and data in real time, regardless of the physical distance between the participants. Unfortunately, support for additional protocol features such as reliability, secrecy, and total ordering in the multicast context requires mor...

Protocol Independent Lightweight Secure Communication

This paper introduces a new protocol independent security mechanism, called PILSC (Protocol Independent Lightweight Secure Communication). PILSC utilizes the security feature of IPv4, defined but not used yet, in order to have standardization in secure communication. We aim to increase the efficiency of the secure data transfer by means of examining the shortages of different security protocols...
