Security analysis of a protocol is an important step toward the public trust on its security. Recently, in 2018, Moradi et al. considered the security of the Wei and Zhang RFID EPC-C1 G2 compliant authentication protocol and presented desynchronization attack and also server/reader impersonation attack against it. Then they proposed an improved version of the protocol. However, in this paper as the  rst third party analysis of this protocol to the best of our knowledge, we present an e cient secret disclosure attack with the complexity of only two runs of protocol and doing O(216) PRNG o ine evaluations. We also recommend that designing a secure protocol by using 16-bit CRCs and 16-bit PRNGs in the framework of EPC-C1 G2 may not be possible and changing this standard to allow the use of lightweight cryptographic functions should be inevitable. In this line, we present an improved version of the Moradi et al. protocol and also prove its security both informally and formally, through GNY logic.

These days, many researchers work on RFID EPC-C1 G2 authentication protocols designing with the use of 16-bit PRNGs. However, thanks to short input/output length of such PRNG functions that makes it feasible to convert it, most of such protocols are vulnerable against full secret disclosure attacks. Recently, Moradi et al. in [1] analyzed an EPC-C1 G2 authentication protocol named 𝑆 𝑆 𝑆 𝑆 𝑆 𝑆 + and presented a revised version of the 𝑆 𝑆 𝑆 𝑆 𝑆 𝑆 + protocol. In this paper, we show that unfortunately the revised version of 𝑆 𝑆 𝑅 𝑅 𝑅 𝑅 +protocol, same as its predecessor i. e. 𝑆 𝑆 𝑆 𝑆 𝑆 𝑆 + protocol, is still vulnerable against full secret disclosure attack. In the presented attack, adversary discloses all secrets of the protocol only by eavesdropping one run of the protocol, impersonating the reader in one run of the protocol and doing only 3 × 216 off-line PRNG function evaluations.

Among gnostic collections of poems, Gulshan raz enjoys particular fame and acceptance, but what is the reason behind it? What is the secret of this book? Those who have dealt with the literary aspects of Gulshan raz have hardly ever been able to justify its reputation and have failed in revealing the secret behind this collection of poems. The writer of this paper believes that in order to discover it, one must deal with the whatness of gnostic experience following a phenomenological approach and ignoring certain expressions involved in Gulshan raz. Accordingly, two types of experience can be distinguished from each other in this work: one is related to the knowledge of mysteries and ontological unity, which involves the secrets of the verses of Gulshan raz from its beginning to its middle, and the other is related to the knowledge of gnostic intuitions (dhawq) and loving states pertaining to the secrets of its final verses.

Background: Considering the high prevalence of psychiatric disorders among infertile women, it seems that gynecologists, psychiatrists, and psychologists should be more attentive to identify and treat these disorders. The aim of this study is to determine the effect of E-cognitive group therapy with emotional disclosure on mentwal health status of infertile women who are receiving assisted reproduction.Materials and Methods: In this randomized clinical trial study, 80 infertile women who were receiving hormonal therapy or other assisted reproductive technologies (ART) were randomly allocated to the cognitive-behavioral treatment (CBT) group or the control group. The CBT group had a weekly 12-hour meeting for a period of three months. They also participated in some painting sessions (art therapy) and written and verbal emotional disclosure (both individually and in group presentation). The Depression, Anxiety, Stress Scales (DASS) test and Penn State Worry Questionnaire (PSWQ) were used for data gathering.Results: Results showed the level of psychological distress decreased in the control group, but not significantly. Psychological intervention in the treatment group significantly lowered the level of psychological distress; the mean score of DASS in all aspects was significant. The difference between the mean score of the two groups after intervention was significant (p=0.001) and also according to ANCOVA (p=0.002). Differences were significant between the mean scores of both groups in the PSWQ (p=0.001), Inventory Test (p=0.001), which was confirmed by ANCOVA (p=0.009).Conclusion: These finding suggest that CBT with emotional self-disclosure promotes coping strategies among infertile women. Results also show that these approaches develop mental health and decrease stress in infertile women. Using a psychiatric approach in medical settings could help infertile women to promote their adjustment with mental health problems due to of in infertility. (Registration Number: IRCT201108247407N2).
