Denial of Service Attack. When the attacker steals the user’s smart card, the attacker can obtain the user’s identity IDi through physically monitoring the power consumption [38]. Through using this, in the password change phase, the attacker can easily set a new password, since it is invalid for verification to simply compare an entered IDi and a stored IDi in smart card. The following is a detailed description: Step 1. The attacker inserts the Ui’s smart card into a terminal, and enters the IDi, PWa and PWa∗, where PWa and PWa∗ are the attacker’s arbitrary new passwords. Step 2. The smart card compares the entered value IDi with the IDi stored in the smart card. At this time, it is obvious that this verification process turns out to be successful, since the entered IDi is the same as the stored one in the smart card. Step 3. The smart card computes PWa = h(PWa b), PWa∗ = h(PWa∗ b) and Na = Ni PWa PWa∗. Step 4. The smart card successfully replaces Ni with the new value Na. If an attacker stole the Ui’s smart card and changed the password to an arbitrary new password as described above steps, then succeeding login requests by the legal user Ui will be rejected, unless they re-register with the GWN again. Therefore, Xxxx et al.’s scheme is vulnerable to a denial of service attack.

Denial of Service Attack. Assume that an attacker has got a legitimate Ui’s smart card. However, in the proposed scheme, the smart card computes C3*=h(C2⊕h(b* PWi*)⊕h(IDi*)) and compares it with the stored C3 in its memory to checks the validity of Ui’s identity IDi and password PWi before the password update procedure. It is not possible for the attacker to guess out Xx’s s identity IDi and password PWi correctly at the same time in polynomial time. Moreover, once the number of login failure exceeds a predefined system value, the smart card will be locked immediately. Therefore, the proposed scheme is secure against denial of service attack.

Denial of Service Attack. A Denial-of-Service Attack (DoS Attack) in computing is a cyber-attack in which the attacker seeks to make a computer or network resource inaccessible to its intended users by temporarily or permanently disabling a host's Internet connected services. This attack is overcome by restricting the size, i.e. not allowing more than a set number of requests from the same identifier. If it reaches the request cap the node is blocked and is unable to connect with the other nodes in the network any further.

Denial of Service Attack. Xxxxxxx et al.’s protocol uses a temporary ID for the patient, which provides message freshness based on session different timestamp T1. The usage of the temporary ID is for person anonymity of the patient, which claimed to be one of important factor of Xxxxxxx et al.’s protocol. TS should always reject any legal patient A’s request in Xxxxxxx et al.’s protocol. The reason is that TS requires to decipher CA to get (XA||PA||T1) at verification phase. However, to decipher the cipher text, TS should choose any pre-share key with the targeting patient after identifying the patient based on XXX∼X. However, TS could not know the real patient with XXX∼T, which is obtained by taking the hash operation of XA, PAand N1. Xxxxxxx, there is only possibility that TS rejects the legal patient’s authentication requests, which results in denial of service. The reason for the possibility of denial of service attack against Xxxxxxx et al.’s protocol is that the protocol provides no method that TS could distinguish the message owner.

  • Level of Service Complex case management with a provider focus is appropriate for members who either choose not to be actively involved or are unable to actively participate in their health care. Complex case management targets members with two (2) or more disease states who need assistance with care coordination, making preventive care appointments, or accessing care to address the members’ chronic health conditions or members who have had an inpatient hospital stay in the last ninety (90) days or members with high dollar claims of over fifty thousand dollars (>$50,000) in six (6) months. The focus is on working with the providers to meet the needs of the individual through communication with the PMP (if applicable), other providers, and the member’s natural support system. The goal is to help members gain optimum health or improved functional capability, in the right setting and in a cost-effective manner. Complex case management with provider focus is the active coordination by the Contractor of care and services between providers while navigating the extensive systems and resources required for the member. It involves comprehensive assessment, determination of available benefits, development and implementation of a complex case management plan directed at the chronic health conditions. At a minimum, the Contractor must provide complex case management services for members discharged from an inpatient psychiatric, drug overdose, or substance abuse hospitalization, for no fewer than ninety (90) calendar days following that inpatient hospitalization discharge. The Contractor must also provide complex case management services for any member at risk for inpatient psychiatric or substance abuse re -hospitalization. Care managers must contact members during an inpatient hospitalization or as soon as practicable upon receiving notification of a member’s inpatient behavioral health hospitalization. The care manager must work with the hospital discharge planner, provider case manager and/or natural supports (i.e. family) to ensure that an outpatient follow-up appointment is scheduled to occur no later than seven (7) calendar days following the inpatient behavioral health hospitalization discharge and transportation is not a barrier to attending the appointment. Complex case management with provider focus includes all of the services and benefits from disease management and care management. In addition,

Specifications for the Customer Facility and the location of the Point of Interconnection shall be set forth in an appendix to the Interconnection Service Agreement and shall conform to those stated in the Facilities Study.

  • Description of Service 2.9.1.1 BellSouth shall make available to <<customer_short_name>> LMU information with respect to Loops that are required to be unbundled under this Agreement so that <<customer_short_name>> can make an independent judgment about whether the Loop is capable of supporting the advanced services equipment <<customer_short_name>> intends to install and the services <<customer_short_name>> wishes to provide. LMU is a preordering transaction, distinct from <<customer_short_name>> ordering any other service(s). Loop Makeup Service Inquiries (LMUSI) and mechanized LMU queries for preordering LMU are likewise unique from other preordering functions with associated SIs as described in this Agreement. 2.9.1.2 BellSouth will provide <<customer_short_name>> LMU information consisting of the composition of the Loop material (copper/fiber); the existence, location and type of equipment on the Loop, including but not limited to digital loop carrier or other remote concentration devices, feeder/distribution interfaces, bridged taps, load coils, pair-gain devices; the Loop length; the wire gauge and electrical parameters. 2.9.1.3 BellSouth’s LMU information is provided to <<customer_short_name>> as it exists either in BellSouth's databases or in its hard copy facility records. BellSouth does not guarantee accuracy or reliability of the LMU information provided. 2.9.1.4 BellSouth’s provisioning of LMU information to the requesting CLEC for facilities is contingent upon either BellSouth or the requesting CLEC controlling the Loop(s) that serve the service location for which LMU information has been requested by the CLEC. The requesting CLEC is not authorized to receive LMU information on a facility used or controlled by another CLEC unless BellSouth receives a LOA from the voice CLEC (owner) or its authorized agent on the LMUSI submitted by the requesting CLEC. 2.9.1.5 <<customer_short_name>> may choose to use equipment that it deems will enable it to provide a certain type and level of service over a particular BellSouth Loop as long as that equipment does not disrupt other services on the BellSouth network. The determination shall be made solely by <<customer_short_name>> and BellSouth shall not be liable in any way for the performance of the advanced data services provisioned over said Loop. The specific Loop type (e.g., ADSL, HDSL, or otherwise) ordered on the LSR must match the LMU of the Loop reserved taking into consideration any requisite line conditioning. The LMU data is provided for informational purposes only and does not guarantee <<customer_short_name>>’s ability to provide advanced data services over the ordered Loop type. Furthermore, the LMU information for Loops other than copper-only Loops (e.g., ADSL, UCL-ND, etc.) that support xDSL services, is subject to change at any time due to modifications and/or upgrades to BellSouth’s network. Except as set forth in Section 2.9.1.6, copper-only Loops will not be subject to change due to modification and/or upgrades to BellSouth’s network and will remain on copper facilities until the Loop is disconnected by <<customer_short_name>> or the End User, or until BellSouth retires the copper facilities via the FCC’s and any applicable Commission’s requirements. <<customer_short_name>> is fully responsible for any of its service configurations that may differ from BellSouth’s technical standard for the Loop type ordered. 2.9.1.6 If BellSouth retires its copper facilities using 47 C.F.R § 52.325(a) requirements; or is required by a governmental agency or regulatory body to move or replace copper facilities as a maintenance procedure, BellSouth will notify <<customer_short_name>>, according to the applicable network disclosure requirements. It will be <<customer_short_name>>’s responsibility to move any service it may provide over such facilities to alternative facilities. If <<customer_short_name>> fails to move the service to alternative facilities by the date in the network disclosure notice, BellSouth may terminate the service to complete the network change.
