Constructing Practical Signcryption KEM from Standard Assumptions without Random Oraclesen-ciphertext security is proven in the standard model under the DBDH assumption, and unforgeability is proven in the standard model under the CDH assumption. The proof technique allows us to achieve strong unforgeability from the weakly unforgeable Waters signature. The validity of the ciphertext o

Sequential Aggregate Signatures Made Shorternature in sequential order. In this case, since many public keys are used and many signatures are employed and compressed, it is important to reduce the sizes of signatures and public keys. Recently, Lee et al. proposed an efficient SAS scheme with short public keys and proved its security without r

Toward Practical Group Encryption the encryptor is capable of proving that some (anonymous) group member is able to decrypt the ciphertext and, optionally, that the corresponding plaintext satisfies some . relation (to prevent sending bogus messages). Finally, in case of a dispute, the identity of the intended receiver can be recov

Experimental Analysis of Attacks on Next Generation Air Traffic CommunicationDS-B is already supported by a majority of international aircraft and will become mandatory in 2020 for most airspaces worldwide. While it is known that ADS-B might be susceptible to different spoofing attacks, the complexity and impact of launching these attacks has been debated controversially by

https://doi.org/10.1007/978-3-8348-9476-2ing with PDP and POR schemes, many cryptography and security researchers have addressed the problem. After the first solutions for static data, dynamic versions were developed (e.g., DPDP). Researchers also considered distributed versions of such schemes. Alas, in all such distributed schemes, the c
