Security strength Sample Clauses

Security strength. We here explain that the scheme satisfies the requirements mentioned in Section 3, together with resistance against the most important attacks. – Confidentiality. In order to construct the session key, the hash function H1 should be evaluated, which requires knowledge of either the secret key DKi or the key DKm. The key DKi is only known by TTP and device, while the second DKm by TTP and MEC. – Mutual authentication. The session key is built using random values derived by device, MEC and TTP. Both MEC and IoT are ensured on the authentication when the calculated value d3 matches with the received one, because only the TTP is able to construct this legitimate construction. Also the TTP is ensured about the identities of the device and MEC, because only the legitimate entities are able to make a valid request. As a consequence, attacks exploiting the authentication like impersonation and man-in-the-middle attacks can not be applied. Since the random values are unique and the identities/keys are updated in each round, replay attacks are also infeasible. – Unlinkability. In order to reveal the relation between the different dynamic identities, the attacker should be able to evaluate the hash function H1 and thus know DKi or DKm. Consequently, only the TTP, which has a table storing the secret key material of the devices and MEC nodes, is able to make the link between different requests. – Forward privacy. If the IoT device is captured and the attacker is able to reveal the security material (XXXx, DKi), then the previous session keys cannot be computed, neither a link with previously sent requests can be made, due to the one-way property of the hash function. The same holds for the MEC. – Session state specific information attack. The session specific information in our system is limited to R1, R2, R3. The first two variables are sent in public in any case and do not directly support to the underlying security. The knowledge of the last value is also not critical for the security of the scheme, even for inside attackers like MEC node and device, since the session key still involves ci , cm,

  • Security Safeguards Contractor shall maintain a comprehensive security program that is reasonably designed to protect the security, privacy, confidentiality, and integrity of District Data. Contractor shall store and process District Data in accordance with industry standards and best practices, including implementing appropriate administrative, physical, and technical safeguards that are no less rigorous than those outlined in CIS Critical Security Controls (CIS Controls), as amended, to secure such data from unauthorized access, disclosure, alteration, and use. Contractor shall ensure that all such safeguards, including the manner in which District Data is collected, accessed, used, stored, processed, disposed of and disclosed, comply with all applicable federal and state data protection and privacy laws, regulations and directives, including without limitation the Act, as well as the terms and conditions of this Addendum. Without limiting the foregoing, and unless expressly agreed to the contrary in writing, Contractor warrants that all electronic District Data will be encrypted in transmission and at rest in accordance with NIST Special Publication 800-57, as amended, or such other standard as the District’s Chief Privacy Officer or designee may agree to in writing. Contractor shall also encrypt any backup, backup media, removable media, tape, or other copies. In addition, Contractor shall fully encrypt disks and storage for all laptops and mobile devices.

  • Security System The site and the Work area may be protected by limited access security systems. An initial access code number will be issued to the Contractor by the County. Thereafter, all costs for changing the access code due to changes in personnel or required substitution of contracts shall be paid by the Contractor and may be deducted from payments due or to become due to the Contractor. Furthermore, any alarms originating from the Contractor’s operations shall also be paid by the Contractor and may be deducted from payments due or to become due to the Contractor.

Security of the Contractor’s electronic media shall be in accordance with the above documents. Effective Program Security shall require the Contractor to address Information Security and Operations Security enabled by the Security Classification Guides. The Contractor’s facility must be able to handle and store material up to the Classification Level as referenced in Attachment J-01, DD Form 254.

You are responsible for contacting the alarm monitoring company to test the compatibility of any alarm monitoring or security system with the Service.

  • Security Standards The Provider shall implement and maintain commercially reasonable security procedures and practices that otherwise meet or exceed industry standards designed to protect Student Data from unauthorized access, destruction, use, modification, or disclosure, including but not limited to the unauthorized acquisition of computerized data that compromises the security, confidentiality, or integrity of the Student Data (a "Security Breach"). For purposes of the DPA and this Exhibit G, "Security Breach" does not include the good faith acquisition of Student Data by an employee or agent of the Provider or LEA for a legitimate educational or administrative purpose of the Provider or LEA, so long as the Student Data is used solely for purposes permitted by SOPPA and other applicable law, and so long as the Student Data is restricted from further unauthorized disclosure.
