Analysis of Key Wrapping APIs: Generic Policies, Computational Security
key management key wrapping cryptographic APIs
2016/5/3
We present an analysis of key wrapping APIs with
generic policies. We prove that certain minimal conditions on
policies are sufficient for keys to be indistinguishable from
random in any execution ...
We present an efficient key wrapping scheme that uses a single wide permutation and does not rely on block ciphers. The scheme is capable of wrapping keys up to 1400 bits long and processing arbitrari...
Consider the task of asymmetric key-wrapping, where a key-management server encrypts a cryptographic key under the public key of a client. When used in storage and access-control systems, it is often ...
