“…Jiang et al proposed an efficient proxy re-signature over lattice. 20 This scheme could re-sign the same message multiple times, but could not resist collusion attacks. In 2020, Fan et al solved the deficiencies of Tian et al's signature scheme and proposed a certificateless proxy re-signature scheme with higher efficiency and shorter private key.…”

“…Therefore, lattice ciphers have gradually attracted people's attention, and the design of lattice cipher schemes has attracted the attention of a large number of cryptographers 15,16 . So many signature schemes based on lattice were proposed 5,6,11,12,17‐23 . Micciancio et al had shown that the difficulty of lattice difficulties in random instances is equivalent to the difficulty of the worst case 24 .…”

As a kind of special digital signature, proxy re‐signature is becoming more and more important in transparent certification and management of group signatures. But most existing proxy re‐signature schemes cannot resist collusion attack. So we construct a scheme by using dual modulus technology and lattice structure. Dual modulus technology can ensure that our solution can resist various collusion attacks. Lattice structure can ensure that our scheme is secure in the postquantum era. Compared with the previous scheme, our scheme is unidirectional and certificateless, is secure in the post‐quantum era, does not require key escrow, can prevent man‐in‐the‐middle attacks, and can resist collusion attacks of proxy and delegatee as well as proxy and delegator. Moreover, our scheme is unidirectional and has better privacy. Furthermore, under the random oracle model, we prove that our scheme is strong nonforgeability against external attackers and the internal key generation center.

Recent Activity Daily Living (ADL) not only tackles simple activities, but also caters to a wide range of complex activities. Although the same activity has been carried out under the same environmental conditions, the acceleration signal obtained from each subject considerably differs. This happens due to the pattern of action generated for each subject is diverse based on several aspects such as subject age, gender, emotion and personality. This project therefore compares the accuracy of various machine learning models for ADL classification. On top of that, this research work also scrutinizes the effectiveness of various feature selection methods to identify the most relevant attribute for ADL classification. As a result, Random Forest was able to achieve the highest accuracy of 83.3% on subject independent matter in ADL classification. Meanwhile, CFS Subset Evaluator is considered to be a good feature selector as it successfully selected the 8 most relevant features compared with Correlation and Information Gain Evaluator.

Proxy Re-Signature (PRS) complements well-established digital signature service. Blaze-Bleumer-Strauss discussed PRS in 1998 for translating a signature on a message from Alice into a signature from Bob on the same message at semi-trusted proxy which does not learn any signing-key and cannot produce new valid signature on new message for Alice or Bob. PRS has been largely ignored since then but it has spurred considerable research interest recently for sharing web-certificates, forming weak-group signatures, and authenticating network path. This article provides a survey summarizing and organizing PRS-related research by developing eight-dimensional taxonomy reflecting the directional feature, re-transformation capability, re-signature key location, delegatee involvement, proxy re-signing rights, duration-based revocation rights, security model environment, and cryptographic approach. Even though multi-dimensional categorization is proposed here, we categorize the substantial published research work based on the eighth dimension. We give a clear perspective on this research from last two-decades since the first PRS-protocol was proposed.
