Highlights A larger number of ACEs predict substantial higher levels of PTSS and anxiety. Experienced exposure and fear of exposure also predict more PTSS and anxiety. Childhood abuse and neglect may exacerbate the impact of exposure on mental health.

Generalized signcryption can adaptively work as an encryption scheme, a signature scheme, or a signcryption scheme with only one algorithm. The paper proposes an efficient certificateless generic signcryption scheme without utilizing bilinear pairing operations. It is proved to satisfy confidentiality and unforgeability against chosen ciphertext and message attacks in an adaptive manner, respectively, in the random oracle model. Due to the lower computational cost and communication overhead, the proposed scheme is suitable for low power and processor devices.
