LEE: Light‐Weight Energy‐Efficient encryption algorithm for sensor networks [PDF]
, 2007 Data confidentiality in wireless sensor networks is mainly achieved by RC5 and Skipjack encryption algorithms. However, both algorithms have their weaknesses, for example RC5 supports variable-bit rotations, which are computationally expensive operations

Enhancement of Secrecy of Block Ciphered Systems by Deliberate Noise
, 2012 This paper considers the problem of end-end security enhancement by resorting to deliberate noise injected in ciphertexts. The main goal is to generate a degraded wiretap channel in application layer over which Wyner-type secrecy encoding is invoked to ...

A note on some algebraic trapdoors for block ciphers
, 2018 We provide sufficient conditions to guarantee that a translation based cipher is not vulnerable with respect to the partition-based trapdoor. This trapdoor has been introduced, recently, by Bannier et al.
