Relations among Privacy Notions for Signcryption and Key Invisible “Sign-then-Encrypt”tacks by combining the functionality of digital signatures and public-key encryption into a single operation. Libert and Quisquater (PKC 2004) extended this set of basic requirements with the notions of ciphertext anonymity (or key privacy) and key invisibility to protect the identities of signcrypt可行 发表于 2025-3-27 03:13:12
Injective Encodings to Elliptic Curvespoint on an elliptic curve in such a way that the message can be efficiently and uniquely recovered from the point. This is for example the case if one wants to instantiate CPA-secure ElGamal encryption directly in the group of points of an elliptic curve. More practically relevant settings include评论性 发表于 2025-3-27 06:17:57

Security Proofs for Hash Tree Time-Stamping Using Hash Functions with Small Output Sizeformula ., where . is the time-success ratio of a collision-finder, . is the ratio of a back-dating adversary and . is the size of the hash tree created in every time unit. Practical schemes use 256-bit hash functions that are just 2.-secure because of the birthday bound. For having a 2.-secure time热心 发表于 2025-3-27 15:51:50

Related-Key Boomerang Attacks on KATAN32/48/64le approach, the KATAN family are secure at present. In this paper, we investigate the KATAN family in the related-key boomerang framework with several techniques. By using an efficient differential characteristics search method, long boomerang distinguishers can be built. Furthermore, the key recovdiskitis 发表于 2025-3-28 02:56:28
