Provably secure and efficient proxy signature scheme
The size of proxy signature secret key in proxy signature scheme based on lattice basis delegation in fixed di-mension or bonsai tree is greater than that of original signature secret key.

Provably Secure Authenticated Encryption
Authenticated Encryption (AE) is a symmetric key cryptographic primitive that ensures confidentiality and authenticity of processed messages at the same time. The research of AE as a primitive in its own right started in 2000. The security goals of AE were captured in formal definitions in the tradition in the tradition of provable security (such as ...

Provably secure certificate less blind proxy re-signatures
Using bilinear groups,an efficient certificate less blind proxy re-signature scheme was proposed based on the proxy re-signature scheme and blind signature scheme.The scheme solves the using of certificate in certificate-based scheme and removes key ...

Provable Security Against a Differential Attack
The purpose of this paper is to show that there exist DES-like iterated ciphers, which are provably resistant against differential attacks. The main result on the security of a DES-like cipher with independent round keys is Theorem 1, which gives an upper bound to the probability of <em>s</em>-round differentials, as defined in <em> ...

Provably secure private-keyless encryption on ideal lattices
Private-keyless encryption (PKLE) addresses the cumbersome challenge of private key management by replacing traditional user private keys with one-time decryption credentials.

Another Look at Provable Security [PDF]
Many cryptographers believe that the only way to have confidence in the security of a cryptographic protocol is to have a mathematically rigorous proof that the protocol meets its stated goals under certain assumptions. However, it is often difficult to assess what such proofs really mean in practice especially if the proof is non-tight, the underlying
