On the Tight Security of TLS 1.3: Theoretically Sound Cryptographic Parameters for Real-World Deployments

Denis Diemert, Tibor Jager
2021 Journal of Cryptology  
AbstractWe consider the theoretically sound selection of cryptographic parameters, such as the size of algebraic groups or RSA keys, for TLS 1.3 in practice.  ...  For some building blocks, such as the symmetric record layer encryption scheme, we can then rely on prior work to establish tight security.  ...  To view a copy of this licence, visit  ...

RP4 Between the MIHF PoS and an MIH non-PoS instance in different BSM network entities.  ...  A PoA is the network side of a layer 2 link that includes an MN as the other end point. Thus, the MIH framework supports both L2 and L3 transports for exchanging MIH information.  ...  The authors would also like to acknowledge the contributions of the whole ETSI BSM working group.  ...
