Toward securing untrusted storage without public-key operations
Adding security capabilities to shared, remote and untrusted storage file systems leads to performance degradation that limits their use. Public-key cryptographic primitives, wid...

A Low-Cost Solution for Frequent Symmetric Key Exchange in Ad-hoc Networks
: Next to authentication, secure key exchange is considered the most critical and complex issue regarding ad-hoc network security. We present a low-cost, (i.e. low hardware-complex...
