“…OAEP is a generic transformation for constructing public-key encryption schemes from trapdoor permutations that was proposed by Bellare and Rogaway. Since then, it has become an important ingredient in many security protocols and security standards like TLS [DR08,Res02], SSH [Har06], S/MIME [RT10,Hou03], EAP [CA06], and Kerberos [NSF05,Rae05].…”

We show that two well-known and widely employed public-key encryption schemes-RSA Optimal Asymmetric Encryption Padding (RSA-OAEP) and Diffie-Hellman Integrated Encryption Scheme (DHIES), instantiated with a one-time pad,-are secure under (the strong, simulation-based security notion of) selective opening security against chosen-ciphertext attacks in the random oracle model. Both schemes are obtained via known generic transformations that transform relatively weak primitives (with security in the sense of one-wayness) to IND-CCA secure encryption schemes. We also show a similar result for the well-known Fujisaki-Okamoto transformation that can generically turn a one-way secure public key encryption system and a one-time pad into a INDCCA-secure public-key encryption system. We prove that selective opening security comes for free in these transformations. Both DHIES and RSA-OAEP are important building blocks in several standards for public key encryption and key exchange protocols. The Fujisaki-Okamoto transformation is very versatile and has successfully been utilised to build efficient lattice-based cryptosystems. The considered schemes are the first practical cryptosystems that meet the strong notion of simulation-based selective opening (SIM-SO-CCA) security.

Avoiding Equal Cost Multipath Treatment in MPLS Networks

This document describes the Equal Cost Multipath (ECMP) behavior of currently deployed MPLS networks. This document makes best practice recommendations for anyone defining an application to run over an MPLS network that wishes to avoid the reordering that can result from transmission of different packets from the same flow over multiple different equal cost paths. These recommendations rely on inspection of the IP version number field in packets. Despite the heuristic nature of the recommendations, they provide a relatively safe way to operate MPLS networks, even if future allocations of IP version numbers were made for some purpose.

“…For an up and running IP network, the IP traffic as seen by the operator for network design and planning purpose is dynamic. With the wide-spread adoption of multi-protocol label switching (MPLS) [10] protocol in the IP network, IP traffic will essentially be transmitted via a virtual-circuit-like label switched path (LSP) from an ingress label switching router (LSR) to an egress LSR. With the introduction of the generalized multi-protocol label switching (GMPLS)[ll] signaling framework, a lightpath can be regarded as a higher order LSP, which defines the logical topology of the IP layer and provides spare capacity for IP traffic.…”
