Categorical composable cryptography: extended version [PDF]
Logical Methods in Computer Science, 2023 We formalize the simulation paradigm of cryptography in terms of category theory and show that protocols secure against abstract attacks form a symmetric monoidal category, thus giving an abstract model of composable security definitions in cryptography.

Application Of Rectangular Matrices: Affine Cipher Using Asymmetric Keys
Cauchy: Jurnal Matematika Murni dan Aplikasi, 2019 In cryptography, we know the symmetric key algorithms and asymmetric key algorithms. We know that the asymmetric key algorithm is more secure than the symmetric key algorithm. Affine Cipher uses a symmetric key algorithm.

ID-based cryptography using symmetric primitives [PDF]
Designs, Codes and Cryptography, 2007 A general method for deriving an identity-based public key cryptosystem from a one-way function is described. We construct both ID-based signature schemes and ID-based encryption schemes. We use a general technique which is applied to multi-signature versions of the one-time signature scheme of Lamport and to a public key encryption scheme based on a ...
